  • Patent number: 11545906
    Abstract: A phase-shifted full-bridge converter and a control method thereof are disclosed. The proposed control method of a phase-shifted full-bridge converter, wherein the phase-shifted full-bridge converter includes a full-bridge switching circuit having a first and a second output terminals, a main transformer having a primary winding and coupled to the switching circuit, and an autotransformer having a primary winding and coupled to the main transformer, includes providing an induced common current flowing through the primary winding of the autotransformer; and causing the induced common current being reflected to the primary winding of the main transformer to cause a primary side current flowing through the primary winding of the main transformer to increase both slopes of a valid duty cycle and a dead-zone period such that the primary side current has a relatively lower transition level and a relatively shorter transition time.
