Magna-Power Current-Fed Power Processing—Ride Through Robustness

Current-Fed Power Processing—Ride Through Robustness

This article was written by Magna-Power Electronics and originally appeared in the March 2019 issue of the IEEE Power Electronics Magazine.

Selecting the best power convert-er topology for a specific application can be somewhat over-whelming considering the advances made in the past 20 years. Many of these advances were accomplished with better semiconductor switches providing faster switching rates, lower on-state voltages, lower power loss, lower power driver requirements, and so on. Selecting the best power convert-er topology must balance the application’s demands with priorities of cost, size/packaging, efficiency, and robustness. Magna-Power Electronics (Magna-Power), a programmable dc power product manufacturer in Flemington, New Jersey, United States, prioritized robustness in its topology selection. The topology choice was driven by the customers’ need for high reliability in demanding industrial environments.
With Magna-Power products often being used in experimental, prototype validation applications, customer satisfaction required consistent power converter performance well beyond typical operating conditions. Having shipped tens of thousands of power supplies, the vast majority of field failures results from customer abuse, such as:

  • corrosion
  • abnormal input voltage such as lightning, power line transients, and power line harmonics
  • output abuse, such as back-fed volt-ages and excessive ac currents
  • susceptibility of electromagnetic interference in abnormal environments
  • poor packaging of power supplies in equipment racks resulting in restrictive air flow and excessive heating.

Typical methods to improve reliability are the implementation of n + 1 redundancy and lowering the mean time between failure. These techniques can only partially improve long-term reliability if the cause of failure is a result of external conditions. For example, a power supply placed in an industrial environment, which is subjected to high incoming voltage transients, will be more reliable at utilizing input rectifiers with a higher blocking voltage rating. In this case, improving reliability with higher-voltage devices can be more beneficial than having redundant power supplies with lower component ratings, which will all fail from the same external environmental condition. Surviving an abnormal external influence, even if operation is temporally aborted, is far better than the product failing and relying on a spare.

One of Magna-Power’s key objectives has been to develop power circuits capable of riding through potentially damaging conditions. Strong ride-through capability, or fault resistance, lowers field returns, reduces cost-ly repairs, and, most importantly, preserves customer satisfaction. Fault protection cannot be achieved under all conditions, but knowing the weak points in a design can give a better understanding to possible improvements.
Most power supply designs in the 1-kW and up power range use a volt-age-fed topology or a similar derivative. As illustrated in Figure 1, the input stage is a dc source feeding a capacitor, bridge inverter, a trans-former for ohmic isolation, an output rectifier, and inductor-capacitor low-pass filter. The weak point of the design is the bridge inverter. If one of the devices should fail or erroneously turn on, the resulting effects can be quite dramatic: failure of other bridge inverter devices, flames, and damage to surrounding circuitry. If the bridge inverter circuit does not switch with a near-perfect volt-second balance, the transformer core will saturate, possibly resulting in similar fail-ure conditions.

Figure 1. A voltage-fed converter

There have been considerable advances in the fault detection of voltage-fed converters. However, protection schemes must still operate on the order of microseconds. Such failures are thermal and device dependent. Protection advances include detection of on-state conduction with antisaturation-sensing circuitry and current-mode controllers that limit peak current through transformers to prevent core saturation. Any external influence causing a wrong switching state can result in a potential failure with little time to take corrective action.

Current-Fed Converter

Figure 2 shows the electrical dual of the voltage-fed converter, i.e., a current-fed converter. The current-fed topology has been around for a long time, but it is rarely commercially deployed because of the need and added cost for creating a current source input plus the demand for a low-leakage transformer [1]. The differences between volt-age-fed and current-fed converters are very subtle. The voltage-fed bridge devices should never short the input dc bus, as opposed to the current-fed bridge devices, which should never open the input dc bus. Second, output inductor L1 in a voltage-fed converter is on the output side of the converter, but it is on the input side of the current-fed converter.

Figure 2. A current-fed converter

As illustrated in Figure 3, the requirement for a current source input can be achieved with a buck converter or chopper operated as a voltage-to-current converter. While this is indeed a negative point of the topology, this added stage can be utilized for protection between the two converter stages.

The inverter stage, which has the primary function of ohmic isolation and voltage transformation, should operate at a near 50% duty cycle. This stage can be operated at a lower switching frequency with virtually no degradation in dynamic performance. All of the converter control is governed by the buck converter stage. A low-leakage impedance for transformer T1 ensures high converter efficiency and low output voltage ripple. During com-mutation of the two inverter poles, the dc bus across the inverter shorts, and current is blocked from flowing through the output stage.

Figure 3. A current-fed converter with a buck converter

With the current-fed converter, the time to protect any semiconductor device is dependent on the switching period of the buck converter and the design of inductor L1; both of these parameters govern the time needed to prevent core saturation of inductor L1. For a buck converter operating at 20 kHz, a typical 10-μs period can easily be deployed to protect controlled semiconductor devices within the normal operating limits. This protection can be applied to the inverter or buck semiconductor switches in the event of erroneous switching states, trans-former shorts, or output diode shorts. During a fault condition, the dc bus across the bridge inverter collapses, protecting the remaining devices from catastrophic failure. With the dc bus cur-rent being limited to a current level set and maintained by the buck converter, core saturation of trans-former T1 is virtually impossible.

With sufficient time, fault protection circuitry can be devised to protect the inverter stage with the buck converter stage and the buck converter stage with the inverter stage. Also, failure of a controlled semiconductor switch is current limited by the buck converter, which prevents catastrophic failures. Because of the extended time for protection, special anti-saturation circuitry is not required.

One additional attribute of current-fed topologies is scalability to higher-power, physically larger systems. Adding a little extra inductance in series with inductor L1 has virtually no effect on system performance. Stages can be easily paralleled without major concern for lead inductances.

Despite the advantages of a current-fed design, voltage-fed designs are far more prevalent in industry. Voltage-fed topologies do require one fewer power conversion stage and have fewer magnetic components. Both of these requirements have an impact on cost and efficiency. Manufacturing a single-board power supply can be more cost-effective when power levels are lower—in the 1-kW and lower range. Many manufacturers gang multiple assemblies of the same design to achieve higher power levels, but such designs can have a negative effect on system reliability by additional parts count.

The Challenges of the Current-Fed Converter

Manufacturing current-fed converters have their challenges in a competitive market. There is an extra power conversion stage taking up physical volume along with the materials cost associated with it. Conventional control circuits cannot be used be- cause of the duality of the design, and these circuits have to be designed from fewer integrated devices. Transformers designed for extremely low leakage inductance require unique core geometries. The demands of tighter packaging and specialized magnetic circuits have required Magna-Power Electronics to vertically integrate its manufacturing operations to minimize outsourcing and to optimize its designs.

Today, Magna-Power Electronics manufactures all its assemblies in house. This decision has helped keep the company competitive in a global market, allowing it to realize the cur-rent-fed topology plus improving quality and delivery times. Manufacturing operations include sheet metal fabrication, powder coating, robotic heat sink and fastener assembly, automated surface mount and through-hole printed circuit board assembly, magnetics winding and core fabrication, computer numerical control machining, wire harness fabrication, final assembly, and testing.

Dranetz HDPQ Family VFD Output Measurements




Dranetz HDPQ Family VFD Output Measurements


Most power monitoring instruments synchronize their
measurements to a stable 50/60Hz voltage source.
The reason is to get accurate readings between the
voltage and current phases.This is fine for the
majority of applications, including when measuring
the input of a Variable Frequency Drive (VFD), but
poses a problem when attempting to measure the
output of a VFD – by design, the VFD output voltage
frequency varies, making it difficult for the power
monitor to synchronize.

Unlike most power monitors, the Dranetz HDPQ
product family can also synchronize to the current
which is very beneficial for use in VFD and other
applications. The instruments default to synchronizing
to the voltage, but can be easily changed to synchronize to
the current. Doing so involves a simplesetup change, and this Application Note describes the required setting.

WHY MEASURE THE POWER AND POWER OF A VFD?  Many VFD monitoring applications are at the VFD’s input to measure the power consumption, harmonics, and power line fluctuations. Being at the VFD input, a

stable 50/60Hz voltage source is available for power  monitor synchronization. However, when evaluating VFD efficiency, susceptibility to PQ issues, and troubleshooting issues with the controlled outputs, it is necessary to measure at the VFD’s output, which does not have a stable 50/60Hz voltage output. Significant errors will result when using most power monitors.

It turns out that the VFD output current has a stable

50/60Hz frequency. See the snapshots below – the top is the voltage and the bottom is the current.


The required current synchronization setting
is located in the Nominal & Frequency tab of the
Dranetz HDPQ Wizard setup. The Sync Channel setting defaults to Channel A Volts, but as shown below, when measuring the output of a VFD, select Channel A Amps as the sync channel instead. This is the only setting change that is required, and all other settings are as usual.

Yokogawa Meters & Instruments Releases AQ6374 Optical Spectrum Analyzer

Yokogawa Meters & Instruments Releases AQ6374 Optical Spectrum Analyzer
-The only instrument able to evaluate both visible and optical communications wavelengths –

Yokogawa Meters & Instruments Corporation announces that it has developed the AQ6374 optical spectrum analyzer and will release it on January 11. The AQ6374 features a wide dynamic range and high wavelength resolution and is capable of precisely measuring the optical spectrum of laser light in the 350 to 1750 nm wavelength range.


Optical spectrum analyzers are used to resolve the wavelength components of optical devices such as semiconductor lasers and fiber lasers in order to assess their characteristics. The AQ6374 will be the only optical spectrum analyzer on offer in the market today*1 that is capable of covering both the visible light wavelengths and the wavelengths used in optical communications.


Development Background

In recent years, optical technology has entered wide use in applications as varied as communications, medical care, home appliances, and material processing. The expansion of these markets has stimulated the research and development of products that use optical technology, and so there is a growing need for high-performance optical spectrum analyzers that can evaluate and analyze the characteristics of laser light.


Conventional optical spectrum analyzers can measure a limited range of optical wavelengths. Commercially-available analyzers are divided into two types: those that can measure the wavelengths used for optical communications (1260 to 1675 nm*2), and those that can measure the visible light wavelengths (380 to 780 nm*3) used in medical care, home appliance, material processing, and other applications. Consequently, institutes that conduct basic optical technology research, manufacturers of broadband light sources, and manufacturers of optical devices used in a variety of fields have had to use more than one optical spectrum analyzer or construct their own measurement system from a spectroscope and other components.


To satisfy such needs, Yokogawa has developed the AQ6374.


Product Features

  1. Wide wavelength range (350 to 1750 nm)

The AQ6374 will be the only analyzer on the market that is capable of evaluating and analyzing both the visible light wavelengths and the wavelengths used in optical communications. With a maximum resolution of 2 pm and the ability to sample power levels at up to 100,000 wavelength points, the AQ6374 can precisely evaluate and analyze a wide range of wavelengths with a single scan. The AQ6374 also features a wide close-in dynamic range of 60 dB, which is sufficient for measuring the side mode characteristics of a semiconductor laser*4. This instrument can thus be used to develop distributed semiconductor devices such as feedback laser diodes (DFB-LD) that emit only one wavelength as well as optical fibers that necessitate measurements over a wide range of wavelengths.


  1. Accurate measurement of the optical spectrum of light

The AQ6374 comes with two additional enhancements. The first is a function that purges the water vapor trapped in its monochromator that can suppress the absorption of light at certain wavelengths. The second is a function that reduces the effect of high-order diffracted light whose wavelengths are 2–3 times that of incident light, a characteristic that all monochromators have due to their design principle.


Main Target Users

Universities and institutes that conduct optical research,and manufacturers of active and passive optical devices


Main Applications

– Emission spectrum measurement for semiconductor and fiber lasers

– Measurement of wavelength transmission characteristics for optical fiber and optical filters


Through its U.S. subsidiary, Yokogawa will exhibit the AQ6374 at Photonics West, a major optical technology trade fair. Photonics West 2017 will be held at the Moscone Center in San Francisco, California, from January 31 to February 2.


*1 Based on a January 2017 Yokogawa market survey

*2 As defined by the International Telecommunication Union Telecommunications Standardization Sector (ITU-T)

*3 As defined by the International Organization for Standardization (ISO) in ISO 20473:2007

*4 Side mode is the spectrum adjacent to the peak of the light being measured; wide close-in dynamic range is the ability to resolve and measure this.


Yokogawa’s commitment to the optical measurement field

Yokogawa entered the optical measuring instrument market in the 1980s and since then has developed this business by focusing on visible-range light sources and optical power meters. In April 2004, Yokogawa acquired Ando Electric, one of the world’s top optical communications measuring instrument manufacturers, and since then has developed products based on this company’s technologies as well as its own.


Yokogawa’s AQ6315, which was available until 2006, was well received as an optical spectrum analyzer that could measure a wide range of wavelengths, from visible light to the wavelengths used for communications. The AQ6374 greatly improves upon the basic performance of this popular model.


In addition to optical spectrum analyzers, Yokogawa offers a wide range of products that meet the needs of its customers. These include our market-leading optical time domain reflectometers (OTDR), optical power meters, and laser light sources.


About Yokogawa

Yokogawa’s global network of 92 companies spans 59 countries. Founded in 1915, the US$3.7 billion company engages in cutting-edge research and innovation. Yokogawa is active in the industrial automation and control (IA), test and measurement, and aviation and other businesses segments.
