ABSTRACT:
The continuous conduction mode (CCM) boost voltage power factor correction apparatus with an average-current control mode of the present invention uses resettable integrators to integrate the difference voltage signal outputted from the voltage error amplifier and the input current signal obtained from detection. The integration results are then compared to control the duty cycle of the switch. Thereby, the input current and the input voltage in the AC/DC electrical power converter have a proportion relation and their phases are the same as each other. The components used in this control method are simpler than the PFC circuit of the prior art. It is easy to integrate in one chip with fewer pins. The apparatus of the present invention has a high power factor and a low total harmonic distortion (THD).
