Abstract
A totem-pole bridgeless power factor corrector and a power factor correction method are provided. The totem-pole bridgeless power factor corrector obtains a duty cycle of next state by a predictive valley-peak current control method, and uses an OR gate element to combine PWM signals generated by an average current control method and the predictive valley-peak current control method, thereby enabling a digital signal processor to update the duty cycle.
