Magnetic-integrated zero-voltage zero-current soft switch full bridge circuit

The present invention relates to a magnetically integrated zero voltage zero current soft-switching full-bridge circuit. The circuit is characterized in that the circuit comprises an inverter, a magnetically integrated network, a rectifier, and an output filter capacitor (Co).The magnetically integrated network integrates a transformer function, an energy storage inductor function and an auxiliary inductor function for realizing soft-switching in a magnetic element. The magnetically integrated network also has various topology variation types to meet the requirements of different application occasions. The whole converter has only one magnetic element so that the number of the magnetic elements is largely reduced and the power density is improved. Furthermore, the zero voltage cutover of all primary switch tubes is realized by using exciting current without an additional auxiliary soft-switching network. A commutation diode at the secondary side can realize the zero current switching. The switching loss is largely reduced, and the switching frequency is improved. The circuit can adopt the phase-shifting control, and also can adopt the unsymmetrical PUM control, thereby having good theoretical research value and use value.
