Earlier this week, Californian company Pre-Switch claimed 99.3% efficiency for a 100kHz electric vehicle traction inverter running at 100kW. It credits this impressive figure to the use of a resonant ...

Sunways has developed new three-phase inverters for residential and small-sized commercial rooftop PV projects. The China-based inverter manufacturer said its new STT-15-30KTL-SE(-S) inverters support ...

High-electron-mobility transistor (HEMT) devices based on gallium nitride (GaN) offer superior electrical characteristics and are a valid alternative to MOSFETs and IGBTs in high-voltage and ...

For cost reasons, kW level inverters deploy Insulated Gate Bipolar Transistors (IGBTs). However for high efficiency and high reliability applications, it is worth considering the use of Super-Junction ...

For IGBTs, the on-state voltage drop is a critical specification to consider. This drop includes both the diode drop across ...

The internet is full of such schematics, so this project is nothing special. I try to make it special by providing more explanations and oscilloscope pictures than usually given. The aim of all such ...
