The invention provides a fully-controlled rectifier circuit comprising an alternating-current power supply, an energy storage and resonant inductor L1, and a fully-controlled rectifier bridge. The fully-controlled rectifier bridge consists of four IGBTs. An emitter of the T1 is connected to a collector of the T2 and serves as a first input terminal; an emitter of the T3 is connected to a collectorof the T4 and serves as a second input terminal; a collector of the T1 is connected to a collector of the T3 and serves as a positive output terminal; and an emitter of the T2 is connected to an emitter of the T4 and serves as a negative output terminal. One end of the alternating-current power supply, the energy storage and resonant inductor L1, and a first input terminal of the fully-controlledrectifier bridge are connected successively and electrically; the other end of the alternating-current power supply is connected with a second input terminal of the fully-controlled rectifier bridge;and a positive output terminal and a negative output terminal of the fully-controlled rectifier bridge are connected with a positive electrode and a negative electrode of a load respectively. Same-phase operation of the current and voltage of the alternating-current input terminal is realized by controlling driving parameters of the IGBTs and using the energy storage and resonant inductor L1; thepower factor of the input terminal is increased; and the harmonic pollution on the grid by the train power supply device is reduced.
