Abstract
A direct-current circuit breaker that includes: an interrupter; a resonance circuit including a capacitor, a reactor, and an activation switch; a voltage detection circuit; a charging circuit including a charging resistor and a charging switch; and a control circuit. The control circuit closes the charging switch to charge the capacitor, and thereafter, the control circuit opens the charging switch when the charging voltage exceeds a first voltage value, and closes the charging switch when the charging voltage falls below a second voltage value that is smaller than the first voltage value.
