要約(日本語): Contact erosion due to an arc discharge is a critical problem particularly for a DC switch or a DC circuit breaker. This work presents influence the arc on contact erosion and resistance in opening and closing contacts in the hybrid DC switch. In opening or closing contacts, a short-duration arc occurred between the contacts and commutated the circuit current from the contacts to the SiC-MOSFET until it extinguished. The arc voltage and current waveforms together with spectrum from the arc were measured. The contact erosion and resistance were examined to clarify the effect of the short-duration arc.
