Power Quality Improvement in BLDC Motor Drive using Fuzzy Controlled Zeta Converter

Jisha Chandran, Jaison Cherian.

This paper presents a power factor corrected (PFC) fuzzy controlled zeta converter-fed brushless direct current (BLDC) motor drive as a cost-effective solution for low-power applications. In this work, by adjusting the dc link voltage of the voltage source inverter (VSI) feeding a BLDC motor, the speed of the BLDC motor is controlled . This paper deals with the implementation of pulse width modulated Zeta converter with power factor correction, lower total harmonic distortion factor and better efficiency. The proposed zeta converter based BLDC Motor drive is implemented to improve the power quality and to obtain unity power factor at ac mains for a wide range of speed control. A MATLAB/ Simulink environment is used to simulate the model to achieve a wide range of speed control with improved PQ (Power Quality) at the supply.
