The devices such as diode and thyristor are generally used in industrial, commercial and residential applications hence need to undergo rectification for their proper functioning and operation. They are connected to the grid comprising of non-linear loads and thus have non-linear input characteristics, which results in production of non-sinusoidal line current. Due to the increasing demand of these devices, the line current harmonics pose a major problem by degrading the power factor of the system thus affecting the performance of the devices. Hence there is a need to reduce the line current harmonics so as to improve the power factor of the system. This has led to designing of Power Factor Correction circuits. A single-stage AC/DC converter achieving power factor correction PFC, intermediate bus voltage regulation, and output voltage regulation is simulated and implemented in open loop. The converter is formed by a boost PFC converter with a two-switch clamped flyback converter into a single power stage circuit. The current stress of the main power switch is reduced due to separated conduction period of the two source currents flowing through the power switch. A dual-loop current mode controller is simulated to achieve PFC, and ensure independent bus voltage and output voltage regulations. This paper aims to achieve simulations results of 24-V/100-W in PSIM to confirm the theoretical analysis of the S2PFC converter

Keywords: PFC, S2PFC, Bus Voltage regulation, Output Voltage regulation, Dual Loop Current control mode, Psim.
