Power Factor Correction Using New Dc-Dc Converter Fed Dc Motor Drive

Abstract

Thestrategyusually used in manufacturing, commercial and residential applications need to go throughadaptationdesigned for their suitableimplementation and operation. They are coupled to the grid comprising of non-linear loads and thus have non-linear input characteristics, which results in production of non-sinusoidal line current. Also, current comprising of frequency components at multiples of line frequency is observed which direct to line harmonics. Due to the increasing insist of these strategies, the line current harmonics create a keydifficulty by degrading the power factor of the system thus disturbing the performance of the strategy. Hence there is a require to reduce the line current harmonics so as to get better the power factor of the system. This has lead to designing of Power Factor Correction circuits.Power Factor Correction (PFC) involves two techniques, Active PFC and Passive PFC. In our systemexertion we contain designed an active power factor circuit using Buck Converter for improving the power factor. Average Current Mode Control method has been implemented with buck converter to check the effect of the active power factor corrector on the power factor. The assistance of using Buck Converter in power factor correction circuits is that enhanced line regulation is obtained with substantial power factor. The proposed concept can be implemented to DC motor drive Applications for two switch buck boost converter by using mat lab/Simulink software.
