Abstract
4H-SiC JBS diodes have been used in an inverter circuit, driving an actual three-phase ac induction motor at power levels up to 2.2 HP. Switching wave forms were measured and compared between inverters based on Si PIN diodes a nd 4H-SiC MPS diodes. The results clearly show a significant reduction in p ower dissipation, in both the diode and the IGBT switch, when SiC diodes re place the Si diodes. The reduction is most evident at the higher temperatur es.
