Why are MOSFETs mostly preferred than IGBTs in DC DC converters?
The design of DC DC converter generally requires small size and high operating frequency. Compared with IGBTs, MOSFETs have the characteristics of small size and high switching frequency (up to several hundred KHZ ~ several MHZ), so they are preferred in DC DC design. Use MOSFETs as power switches. At the same time, MOSFETs are mainly used in several watts to hundreds of watts, and IGBTs are mainly used in several hundred watts to several kW.
