Power factor correction by PFC boost topology using average current control method

Different power converters like ac-dc or dc-dc are widely used for their flexible output voltage and high conversion efficiency. Mostly these converters are used in various electronic devices and they are designed to regulate the output voltage even in the variation of load current and input voltage. Presently, there is increasing demands of high power factor and low total harmonic distortion in the current drawn from the utility. There is a requirement of good power quality; significant efforts have been made for the developments of the PFC converters. The boost topology is widely used as PFC converter for its simplicity and efficiency. Conventional boost PFC converters are composed of a full bridge AC to DC diode rectifier followed by a boost converter. The bridge rectifier offers high conduction losses which lowers the system efficiency. A rectifier with the boost pfc topology has been analyzed in this paper to improve the power factor and power quality. Here, the open loop uncontrolled rectifier has been analyzed using Microsim Pspice software and later the controlled rectifier with pfc boost topology has been analyzed by using Matlab.
