Abstract (in Japanese) (See Japanese page) 
(in English) In recent years, with the increase in demand for DC power distribution, hybrid DC circuit breakers in which electrical contacts and semiconductor elements are connected in parallel have attracted attention. When SiC-MOSFET with low on-resistance is used as a semiconductor element, it is possible to realize arc-less interruption in which direct current is commutated from the contact to the semiconductor by the molten bridge voltage formed between the contacts when opening. In this paper, we investigate the commutation characteristics by varying the contact opening speed and the gap length, and investigate and discuss the stability of the molten bridge.
