Abstract

A control apparatus of a power factor corrector is presented to simultaneously control a plurality of power transformer operated under the critical conduction mode, so that the totally transforming efficiency and transforming power of the power factor corrector can be promoted. The apparatus comprises: a control circuit of the primary power transformer for feedback of an input voltage signal, an output voltage signal and a primary current signal, and to output a primary gate control signal to control the primary power switch; at least a control circuit of the secondary power transformer, for receiving the primary gate control signal and outputting a secondary control signal to control the secondary power switch; and a phase separation circuit, for receiving the primary gate control signal to control a gate output driving circuit, so that the gate output driving circuit outputs the secondary gate control signal.
