Power Factor Improvement in Switched Reluctance Motor Drive

Abstract

This paper presents Switched Reluctance Motor (SRM) has inherent mechanical strength without rotor winding and permanent magnet. The high speed drive systems are much interested in the field of industrial applications due to the compact size, reliability and high efficiency. A new single-phase power factor corrected converter is proposed to improve the input power factor for an efficient Switched Reluctance (SR) motor drive. The power factor correction has been done on the basis of phase current waveform, fourier analysis and Total Harmonic Distortion (THD). In order to improve the power quality in terms of Power Factor Correction (PFC), reduce the THD at the input AC side. The need for PFC in SRM systems supplied from single-phase mains. It is shown that for certain applications, a PFC circuit has to be implemented. The developed PFC circuit is connected with input side of SRM. The power factor increases and almost negligible input current THD of 2.62% is achieved. The simulation of switched reluctance motor drive has been done using MATLAB.
