In order to improve the power quality in terms of Power Factor Correction (PFC), reduce the total harmonic distortion (THD) at the input ac side and output the regulated dc several converter topologies have been introduced such as buck, boost, and buck-boost dc-dc converters. This paper presents PFC with boost converter which improves the PFC along with high output regulated dc using PI controller. The high speed drive systems are much interested in the field of industrial applications due to the compact size, reliability and high efficiency. In recent, the demands of high speed drives are much increased due to the mechanical advantages of high speed system. SRMs (Switched Reluctance Motors) have simple structure and inherent mechanical strength without rotor winding and permanent magnet. This paper also presents a new controller design for switched reluctance motor drive system. The proposed converter consists of one switch for each phase is the least number of switches among the converters used in the switch reluctance motor drive and also this converter performs phase current commutation faster. The simulation results based on Matlab/Simulink software are discussed in detail in this paper.
