Abstract :
Nowadays, low Power Factor (PF) is a serious problem that gained more importance in power electronics area. In this paper, single phase PFC using Buck-Boost circuit topology under linearization voltage control is realized. Here the nonlinear load considered is the diode bridge rectifier, and a Buck-Boost converter is connected to its back end for PFC. The switching of buck-boost converter is done by comparing the dc control signal with a saw tooth wave and its switching frequency is set to 100 kHz. The simulation analyses are carried out in Matlab/Simulink software. The effect of PFC Buck-Boost circuit on PF and the sinusoidal nature of line current are analyzed by the simulation results. Its effectiveness is experimentally validated by means of a self designed prototype. Experimental results show that, Buck-Boost circuit topology have an excellent ability for PFC. It makes the supply voltage and current in phase to each other and thus approximate the PF to unity.
