Description
Summary:This paper explains the advantages of using Wide Bandgap (WBG) semiconductor made of Silicon Carbide (SiC) by the characterization of power efficiency and losses of SiC inverter of 15kVA/540V and the analysis of EMI and overshoot of commutation at high switching frequency. The measured power efficiency of inverter can be higher 99%. This inverter also implemented in to electromechanical chain to drive an aeronautic motor (type PMSM). However, faster switching (higher di/dt and dv/dt) of SiC inverter, at higher frequencies, it is necessary to identify the electromagnetic impact (EMI) and the overshoot switching voltage. The experimental results will be shown the interesting of this technology and the impact at high switching frequency.
