In this paper, electrical and thermal comparison analyses are performed in Multichannel Voltage Source DC/AC converter in charge of supplying several loads with AC sinusoidal waveforms, as required by oncoming latest power applications. A comparison with silicon device’s state of art is made: electrical and thermal performances of main 650V transistors families (2nd Generation 650V SiC MOSFET devices and MDmesh M5 650V Silicon MOSFETs) are evaluated where the new 650V SiC MOSFET device is in used as switch in the inverter high frequency leg and the 650V silicon MOSFETs are used as switches in the inverter line frequency leg. The right combination of SiC and Silicon MOSFETs switches will be proposed increasing the system efficiency giving to the market a super green energy saving solution
