Abstract：This paper presents a dual-loop control method which is applied to high-power active power factor correction circuit on the research of conventional power factor correction control circuit. The method adopt dual-loop control which is include voltage loop and current loop to achieve the control of the power factor correction circuit. This paper establish the small-signal model and simulation model to analysis and research working principle and mode of the control method.Finally, build the actual circuit to verify this control method.
