The embodiment of the invention discloses a novel full-bridge DC converter based on a current doubling rectifier. A primary side comprises a full-bridge inverter circuit composed of first to fourth switching tubes, a first isolation transformer, a second isolation transformer and a voltage stabilizing capacitor. A secondary side comprises a current doubling rectifier composed of first to fourth rectifier diodes, a first filter inductor and a second filter inductor, and also comprises a DC power supply and an output filter capacitor. The novel full-bridge DC converter overcomes the problems ofnarrow zero-voltage switching range, large primary side circulation loss and the like of a traditional converter, and is simple in circuit structure and high in conversion efficiency.
