MoP-41 Analysis and Compare of Si and SiC MOSFET on Bidirectional Grid-Connected Inverter with PSIM

抄録

This paper compare with Si and SiC MOSFET on bidirectional inverter with. Bidirectional DC-AC inverter can allow energy from the grid to DC bus and DC bus energy injection to the ac grid. SiC MOSFET has significant performance improvement compared to traditional Si devices, such as lower device loss and higher reliability. Finally, a bidirectional converter is simulated to verify the precision of control strategy and analysis the device loss.
