Abstract
Within a direct current hybrid circuit breaker (DC HCB), a capacitance is provided in a semiconductor switch path in series with a semiconductor switch and the semiconductor switch is in parallel with a surge arrestor to facilitate opening the DC HCB. The semiconductor switch path is connected in parallel with a mechanical switch path that includes a mechanical switch. The circuit causes the current through the mechanical switch to ramp down while the current through the semiconductor switch ramps up to a supply current. The mechanical switch can open without current and against no recovery voltage.
