Abstract

In this portion, the BLDC motor drive is proposed with quasi Z-source inverter (qZSI) interfaced with separate DC supply. The closed loop system is performed with the back EMF estimation control with PI controller. The proposed Z- source converter is controlled and the gate switching signals are provided by the Pulse Width Modulation (PWM). The DC- AC inverter is Z- source inverter which performs both conversion and inversion operation of proposed system. The bridges of the inverter power switches are controlled by proposed control methods. The PI controller with the current regulator provides the gate signals to the inverter part which act as the input supply for the BLDC motor drive. The performance of the BLDC with proposed system is verified using MATLAB/Simulink.
