摘要：The present application discloses a power converter and a controlling methodthereof. The power converter at least comprises an inductor, a parasitic capacitor, an
energy storage switch and a free-wheeling switch, and the controlling method is used forenabling the energy storage switch to maintain zero-voltage turn-on during the normaloperation of the power converter. The controlling method comprising: within a switchingperiod, the free-wheeling switch is turned on again for a preset time after the free-wheeling switch is turned on and turned off for the first time and after the inductor andthe parasitic capacitor resonate, so that a voltage between two terminals of the energystorage switch can decline to zero, and when the voltage between two terminals of theenergy storage switch declines to zero, the energy storage switch is turned on, therebyentering the next switching period of the power converter.
