Abstract
A control method for a DC/DC converter and a DC/DC converter are provided. The method includes: providing a primary side driving signal to drive one or more primary side switches of the primary side circuit; providing a sixth signal, a fifth signal, a seventh signal and an eighth signal, where a phase shift angle exists between the sixth signal and the primary side driving signal, and the sixth signal, the fifth signal, the seventh signal and the eighth signal in turn have a predetermined phase difference; driving a sixth switch, a fifth switch, a seventh switch and an eighth switch according to the sixth signal, the fifth signal, the seventh signal and the eighth signal, respectively; where the switching frequency of the sixth signal, the fifth signal, the seventh signal or the eighth signal is half of the switching frequency of the primary side driving signal.
