The circuit compris: a mutual inductance detector (T), a zero-crossing comparator (10), a voltage detection circuit (20) and a controller (30). A primary winding of the mutual inductance detector is connected between an inductor (L) and a first capacitor (C1) in ries. The zero-crossing comparator detects the zero-crossing voltage of the mutual inductance detector. The voltage detection circuit detects the output voltages at two ends of the first capacitor. The controller outputs a driving signal to control the working of a first switch tube (Q1) and a cond switch tube (Q2), wherein the controller is t as follows: after the first switch tube is controlled to be shut off, controlling the cond switch tube to be shut off when the zero-crossing comparator detects that the mutual inductance detector changes from a positive voltage to a zero voltage; and after a pre-t dead-zone time, controlling the first switch tube to conduct for a pre-t duration, and after the first switching tube is shut off, controlling the cond switch tube to conduct for a cond pre-t duration during the pre-t dead-zone time.
