In recent years, the demand for energy is increasing rapidly, leading to an expanded use of power electronic systems across various applications including residential, industrial, commercial, and aerospace sectors. This paper presents an effective active wave shaping control scheme designed to improve power quality by enhancing power factor and reducing total harmonic distortion (THD) in pulsed input currents from uncontrolled diode bridge rectifiers, while also regulating the output DC bus voltage. The proposed method employs a continuous conduction mode (CCM) boost converter with constant frequency operation, which minimizes inductor current ripple and results in lower RMS currents, thereby reducing electromagnetic interference. The primary objective of this work is to develop an active power factor correction (PFC) control circuit utilizing variable duty cycle control, which eliminates the need for inductor current sensing while maintaining satisfactory performance in power quality. Simulation results demonstrating the effectiveness of the proposed scheme under varying load conditions are presented, emphasizing its capability to achieve near-unity power factor and meet THD specifications.
