One-stage power factor correction (PFC) with output electrical isolation. The Converter has a configuration of combining a boost circuit and a forward circuit in one power stage. To relieve the voltage spike caused by the leakage inductance of the power transformer, two bulk storage capacitors are used. The same power switch is shared by the PFC circuit and the power conversion circuit. Due to its simplified power stage and control circuit, this converter presents a better efficiency (87%), lower cost and higher reliability. Detailed steady state analysis results show this novel converter has both good power factor correction and excellent regulation capabilities. With PSPICE simulation and experimental results, a measured power factor of 0.99 was obtained by this single switch converter.
