Design and Development of SEPIC Converter Fed BLDC Motor Drive for Photovoltaic Application

Abstract

In this paper, a solar photo voltaic (SPV) array fed through SEPIC and VSI to BLDC motor. Even though BLDC driver design part is quite complicated, it’s mostly preferred because of its efficiency and High-Power density in now a day and it difficult to maintain PV voltage constant at all time. To maintain PV output voltage constant, Converter is required. Various converters are in practice, among all converters, SEPIC provides non-inverting output voltage and perform both buck as well as boost operation. Three phase VSI is used for achieve electronic Commutation in order to run BLDC motor. Finally, DC voltage from SEPIC that fed to BLDC through three phase VSI. This paper mainly proposes a PV cell integrated SEPIC converter feeding a rated voltage to BLDC motor. MATLAB/SIMULINK based model is developed and simulation results are presented.
