SOFT SWITCHING OF INTERLEAVED BOOST CONVERTER FED PMBLDC MOTOR USING PI AND FUZZY CONTROLLERS

Abstract

This paper proposes an improved interleaved boost converter topology for soft switching of VSI fed PMBLDC motor. Six switch and four switch converter configurations are employed for the proposed boost converter under Zero voltage switching and Zero current switching. The proposed boost converter for PMBLDC motor under various operating condition are implemented in MATLAB/SIMULINK environment. The feasibility of six switch and four switch converter by for PMBLDC motor is explored. A comparative evaluation of speed control of six switch and four switch inverter with fed PMBLDC motor PI and FUZZY controllers has been made discussed in this paper.
