A single stage single switch power factor correction converter

چکیده
The flyback-flyback single stage converter operated in DCM+DCM is easy to control bus voltage, but it hard to control stress of switch. We propose a new converter having low voltage stress on its switch. The flyback converter is simplified into buck-boost form. Then the PFC flyback transformer is replaced by an inductor The switch of both PFC and DC/DC stages are merged, and a diode is used to force the direction of power flow. A 30W prototype is built to evaluate the performance.
