  "textContent": "A direct-current breaking device includes a main circuit breaker inserted on a DC line, a resonant circuit connected in parallel with the main circuit breaker, and a MOSA connected in parallel with the main circuit breaker via the resonant circuit. The resonant circuit includes first, second, third, and fourth switching elements, a capacitor, and a reactor. A first circuit unit including the first switching element and the second switching element connected in series with each other, and a second circuit unit including the third switching element and the fourth switching element connected in series with each other are connected in parallel. The capacitor is connected between a connection point of the first switching element and the second switching element and a connection point of the third switching element and the fourth switching element to constitute a bridge circuit. The bridge circuit and the reactor are in series with each other.",
