The BiDirectional Field-Effect Transistor (BiDFET) can enable circuit topologies requiring four-quadrant switches, that were earlier designed using discrete combinations of MOSFETs, IGBTs, GaN HEMTs, and PiN diodes. The monolithic nature of the BiDFET allows lower device count, smaller switch volume, lower inductance, and simpler packaging, and hence more reliable and … [Read more...] about Power Conversion Systems Enabled by SiC BiDFET Device

Totem-Pole PFC Reliability and Performance Improvement With Advanced Controls
Totem-pole power factor correction (PFC) is a simple and highly efficient topology. It is being widely used in high-density and high-efficiency power supply design. However, engineers still face many design challenges, including PFC current reversing prevention at input voltage drop, lightning surge protection, current harmonic reduction, and ac crossover current spike … [Read more...] about Totem-Pole PFC Reliability and Performance Improvement With Advanced Controls
Heterogeneous Integration: A Promising Technology to Future Integrated Power Conversion Electronics
Since its renaissance, heterogeneous integration (HI) where unique merits of different silicon or III-V technologies, has been widely explored in many power electronics and achieved remark- able success. It is known that the success of power conversion electronics is mostly attributed to the low-power, fast-response, and accurate mixed-signal control circuitry and the low-loss, … [Read more...] about Heterogeneous Integration: A Promising Technology to Future Integrated Power Conversion Electronics
Flexible and Efficient MMC Digital Twin Realized With Small-Scale Real-Time Simulators
The decreasing trend in the price of computational power has led to the evolution of various tools intended to support development processes in power electronics.
