Analysis and Design of Signal Stage AC/DC Converter with Resonant Model PFC

A single stage AC/DC converter with resonant model PFC has been deeply studied in this paper by mathematic analysis. The following results have been revealed: (1).The working conditions for the circuit have been derived and can be expressed by the formulas, which can be used to select the parameters of the circuit; (2). It has been proved that the bus voltage decreases if output power increases and the turn-on time is kept constant; (3). The optimal controlling strategy for regulating the output voltage has been put forward. In order to verify the theoretic analysis conclusions, the simulation results and experimental results have been given out. The theoretic analysis conclusions and math formulas have provide a new tool for designing the circuit
