摘要：
A new simplified control scheme is proposed for AC-DC electrolytic capacitor-less converters operating in continuous conduction mode (CCM). The proposed method has a single-loop controller responsible for both regulation and power factor correction (PFC). In comparison with the two-loop conventional CCM current mode controller, the proposed scheme does not need a multiplier or extra sensors hence simplifying the control circuitry and its design procedures. Modelling of the closed-loop converter is addressed and experimental results are provided to show the feasibility of the control scheme.
