  1200V SiC Hybrid IGBT Modules for High Frequency Applications

  The switching frequency in those applications is usually higher than 20kHz, thus exceeding the range for which standard industrial IGBTmodules are optimized for. Since several years Mitsubishi Electric is offering a dedicated IGBT-series for those high frequency applications, called NFH-series. For reducing the switching loss it is using IGBT-chips with an optimized trade-off between Vce(sat) and Eoff. As next innovation step Mitsubishi Electric now is introducing it’s Silicon Carbide Chip...

  LV100 - a Dual Power Module for the Next Generation Railway Inverters

  The power module topology is half bridge. The main intention for creating such dual power module is reducing the module’s internal stray inductance. In order to minimize the internal voltage spike – one of the bottlenecks for keeping the RBSOA at maximum inverter output current. Each new chip generation shows increased current switching slope di/dt causing higher overvoltage spikes inside the package if the power module’s stray inductance would be kept constant. The issue becomes even more...
