Abstract(in English) | A hybrid circuit breaker consists of power semiconductor devices and a varistor connected in parallel with an electrical contact. In this study, we use SiC-MOSFET and contacts made from tungsten and carbon, which have high melting and boiling temperatures, to commute the contact current to MOSFET by the molten metal bridge voltage formed between contacts without arc discharge Arc formation processes and current commutation characteristics of each contact at the condition of DC 50 V, 150 A were investigated. As a result, arcless commutation was successfully demonstrated when using each contact. |
