A full-bridge module, a hybrid direct current circuit breaker of a full-bridge module and an application method, the full-bridge module comprising: two power electronic units (1, 2, 3, 4), two diodes (5, 6), a resistor (R₁) and a capacitor (C); the two power electronic units (1, 2, 3, 4) are in reverse series connection to form an upper bridge arm; the two diodes (5, 6) are in common anode series connection or common cathode series connection to form a lower bridge arm; and once the resistor (R₁) and the capacitor (C) are in parallel connection, same are connected between the upper bridge arm and the lower bridge arm.
