Fuel Cell Fed BLDC Motor Drive

Abstract

Fuel cell provides ultra clean, high efficient electric energy rather than other energy resources. It is suitable for hybrid electric vehicle application since it does not emit any pollutant. Hence the fuel cell is used as source in this paper. A non isolated resonant PWM ZVZCS high step up DC-DC converter is used to boost the voltage level obtained from the full cell. This converter reduces the switching loss, eliminates the diode reverse recovery problem thereby increases the step up ratio and efficiency. The boosted voltage is given to the three phase inverter circuit to supply the stator current of BLDC motor. This model is simulated using MATLAB software and performance parameters were analyzed. Keywords - Resonant PWM, ZVZCS, high step up, step up ratio
