Cover Story
SiC Based Totem Pole PFC for Industrial Power Supplies

For industrial power supplies, energy efficiency is a key product feature since any energy, which is not delivered to the load but is converted to waste heat, is a direct cost factor in system operation. In addition, any waste heat from inefficient energy conversion results in additional demands on the air conditioning system.

Design and Simulation
The Power of Dowell's Equations and Curves

The standardized curves of Dowell's equations are a superb tool for designing better high-frequency magnetics. It is not sufficient to simply use a wire or foil of one skin depth or less. Excessive losses can continue at high frequencies. A careful balance of layer count and wire or foil count is needed to reach an optimum design. Using the numerical curves, instead of the original equations, provides a shortcut path to better understanding of winding design.

Hybrid Converter Simplifies 48 V/54 V Step-Down Conversion in Data Centers and Telecom Systems

There has been a shift in data center and telecom power system design. Key applications manufacturers are replacing complex, expensive isolated 48 V/54 V step-down converters with more efficient, nonisolated, high density step-down regulators (Figure 1). Isolation is not necessary in the regulators' bus converter since the upstream 48 V or 54 V input is already isolated from hazardous ac mains.

Wide Bandgap
Layout Considerations for GaN Transistor Circuits

Gallium nitride (GaN) transistors have been in mass production for over 10 years. In their first few years of availability, the fast switching speed of the new devices - up to 10 times faster than the venerable Si MOSFET - was the main reason for designers to use GaN FETs.
By Alex Lidow Ph.D., CEO and Co-founder, Efficient Power Conversion

MOSFET
1200 V Discrete MOSFETs in a Comparison with the HighSpeed 3 IGBTs for Servo-Drive Systems

For applications like servo drives, size and weight are very important, however, cooling capability is limited. For this reason, discrete CoolSiC MOSFETs are the ideal solution for fulfilling these requirements and improving performance. In addition, the reduced losses allow for the implementation of a zero-maintenance fanless design. In addition, the motor and drive can be integrated, and therefore reduce the control cabinet size, and simplify cabling.

Power Management
Bidirectional Wireless EV Charging - Smart Grid Integration at Highest Comfort Level

The rate of electrification of the mobility in industries or transportation depends upon the deployment of the charging infrastructure. The existing solution, namely conductive charging, has several concerns in safety, robustness and comfort due to plugging-in of huge cables, especially for higher power. Wireless charging is touted to provide a safe, clean, and autonomous solution.

Design and Simulation
3D Bond Wire Modelling and Electro-Magnetic Simulation Accelerates IGBT Module Development

Speeding up the electro-magnetic module design for maximum Chip performance utilization and highest robustness with latest tools for bond wire routing and electromagnetic simulations.
By Raffael Schnell, SwissSEM Technologies AG and Samuel Hartmann, MFis GmbH

EMC
GaN Transistor Eliminates EMC at Source

EMI problems are often the last major bottleneck at the end of product development. Modelling and first measurements help to reduce the risk, but especially when a compact design is required, there is little space for last-minute changes. As time scales slip, the prices of the components used increases in proportion to the desperation and pressure to get the unit to market.
By Nigel Springett, Ing B?ro Springett

Technology
Innovative Manufacturing Approach Reduces Costs and Optimizes Electrification Time to Market

Manufacturers looking to enter or expand their electrification business often find themselves balancing key production requirements with the unpredictability of an emerging market where best-practice standards are still evolving. To meet these challenges, Comau is rethinking electrical motor and transmission assembly by fully integrating design validation, resin verification, rotor preparation/winding, and multi-model manufacturing flexibility as part of a functional, efficient and versatile operational philosophy.

Cover Story
BCMs Transform High Voltage Batteries into SELV Systems

The power architectures of pure electric (EV) and hybrid vehicles store and distribute power at a mix of voltages to power a wide variety of sensing, control, safety and infotainment subsystems. This presents a cost, space, and weight challenge for the power storage and power delivery network, which hybrid vehicles solve with a 48V battery and 48V distribution system, but EVs solve with high voltage batteries (800V, 400V) and a 48V distribution system.

Converter
"This Is Not Your Father''s Active Clamp Flyback (ACF)"

Conventional flyback converters have a disadvantage due to the ringing caused by the transformer leakage inductance and the main switch parasitic capacitance resonance; this causes a high voltage stress on the switch. In addition, the leakage inductance energy is wasted in a passive clamp, such as most commonly used RCD snubbers, limiting converter efficiency and resulting in thermal dissipation.

Design and Simulation
Designing a Double-Pulse Test (DPT) System to Enable Correlation of Dynamic Characteristics

When evaluating power transistors for your power converter design, it is important to choose the right device for your application. Ideally, datasheets from power semiconductor suppliers would provide consistent results enabling engineers to compare dynamic parameters. For dynamic switching characteristics, this is easier said than done. A standard test system designed to characterize wide-bandgap (WBG) power transistors must keep parasitics small and consistent from system to system. This article discusses important considerations when designing a standard DPT system used to correlate results between multiple test systems.

Capacitors
Vibration-Proof Capacitor Technology

Many of us will have seen the effects of excessive vibration on equipment, ranging from abnormal wear and loosened fixings to actual breakage of components. Mechanical equipment can be made immune by traditional methods such as locking components down with extra fixings or by deliberate isolation of sensitive areas using anti-vibration mountings. However, when electronics is introduced, there can be thousands of small components that may be susceptible to damage.
