Power Factor Correction and Speed Control of BLDC Motor Drive Fed by Zeta Converter
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 12
Abstract
This paper proposes a brushless dc (BLDC) motor fed by zeta converter for power factor correction (PFC). A single phase supply followed by an uncontrolled bridge rectifier and a Zeta DC-DC converter is used to control the voltage of a DC link capacitor .The PFC-based zeta converter is designed to operate in discontinuous inductor current mode thus utilizing a voltage follower approach which requires a single voltage sensor for DC link voltage control and PFC operation. The speed variation in the BLDC motor is achieved by varying the DC link voltage. The DC link voltage is calculated corresponding to the duty cycle of the converter switch. The proposed drive with zeta converter is realized as an efficient method for power factor correction in low-power applications also. A MATLAB/Simulink is used to simulate the developed model to achieve the range of speed control with high power factor and improved Power Quality at the supply.
