This paper investigates a converter topology for driving high-speed electrical machines. Such solution is meant to be an alternative to SiC MOSFET based inverters which have been considered a profitable choice especially in the aeronautical field. It allows a reduced number of SiC devices and a good tradeoff between EMI, insulation stress and reduced switching losses. To this purpose a modified version...
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...
