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
