Abstract
A power conversion circuit and a power conversion circuit control method. The power conversion circuit determines polarity of an alternating current voltage by using a PFC circuit controller, determines, based on a current of an inductor, a signal for controlling a secondary switch to be turned off, determines, based on a voltage at a midpoint of a series connection between a switching transistor Sand a switching transistor S, a signal for controlling the secondary switch to be turned on again and a signal for controlling a primary switch to be turned off, and performs PWM control on the switching transistor Sand the switching transistor S
