Description
Summary:This paper presents a new configuration of a dc power supply with power factor correction using integration of flyback and forward topology in parallel connection. Flyback converter is used for power factor corrector and it operates in discontinuous conduction mode so that it becomes as a natural resistance. Forward converter is used as a dc regulator and operates in continuous conduction mode. A prototype circuit, which has 20 Volt of output voltage and 5 A of output current is designed and tested by a simulation and experiment. According to the simulation and experiment results, the power factor of this circuit can be achieved up to 0.96 and the input current meets the international harmonics standard of IEC61000-3-2 class A and class D so it can be used as power supply for computer, monitor and television.
