This paper presents a study on two converter topologies suitable for driving high-speed three-phase electrical machines. In such applications the use of standard inverters with Si-based IGBTs may lead to high switching losses due to the elevated fundamental frequencies of high-speed machines. The use of wide bandgap devices allows reducing losses at high switching frequencies but problems related...
Due to size and weight limitations, possible integrations of power electronics devices with electrical machines and propulsion engines are welcome in More-Electric-Aircrafts (MEA). Consequently, power converters are required to operate in harsh environments with high temperatures. SiC power devices are preferable in this context since they can tolerate high junction temperature and contribute reducing...
