| Abstract(in English) | Recently, a hybrid DC circuit breaker consisted of metal contacts, semiconductor devices and a varistor is intensely studied because of the large demand of DC power distribution. We are studying a hybrid DC circuit breaker for high voltage and high current operations. In the research, a simulation model of electric contacts is quite useful to evaluate the circuit parameters. this report shows the changing of contact resistance with and without current commutation by a semiconductor switch. As a result, the contact resistance in the experiment with commutation increased rapider than that without commutation. |
