Enhanced Performance of Solar PV Array-Based Machine Drives Using Zeta Converter

Application of renewable energy fed machine drives in various applications curtails the plant energy demand in day to day life. This suggests the design of renewable energy-based machine drives for medium to high rated applications is inveterate. Concentration on socio-economic type machine drives such as BLDC motor drives fed through solar PV array offers an efficient performance of the operation. This paper presents the design and performance of solar PV array fed brushless DC motor drive using the Zeta converter control technique. The Zeta converter technique extort the highest energy from solar PV array to obtain the effective performance of the BLDC motor. This technique avoids the additional detecting sensors and reading the fundamental switching frequency instead of the high switching frequency of voltage source inverter (VSI). This results in reduced switching power losses. Also, the proposed zeta converter control technique allows smooth starting and speed control of the BLDC motor. The design of solar PV array fed through BLDC motor is performed using the MATLAB/Simulink and simulation results are presented.
