REGULATION OF OUTPUT VOLTAGE IN BOOST POWER FACTOR CORRECTION CONVERTER WITH ELECTRO MAGNETIC INTERFERENCE FILTER

Abstract

This paper deals with the closed loop control of a Boost Power Factor Correction (PFC) Converter with Electro Magnetic Interference (EMI) Filter to regulate the output voltage for the source side and load side disturbances. Circuit model for closed loop controlled boost power factor correction converter is developed. A controller is used to regulate the output voltage. The converter is simulated for resistive load. Using the proposed control scheme, the improved power factor at the line side of the converter and regulated output voltage on the load side of the converter are obtained.
