Advances in safety features, comfort and infotainment systems in automobiles are escalating power requirements, challenging power systems engineers to meet the growing power demands with restrictions in weight and space. Over the last decade, the typical 12V power requirements have increased from 1.2kW to 4kW co

The power-semiconductor switches used in power supplies and inverters are based on two technologies, namely MOSFETs and IGBTs. MOSFETs can operate at relatively high switching frequencies significantly above 30 kHz but, unlike IGBTs, they have a very large chip surface area.
A new generation of IGBT modules f
