Design and Analysis of Zeta Converter for Automotive Mechatronics Applications

Abstract

This study deals with power factor correction converter based bridgeless zeta converter for brushless DC (BLDC) motor drive for medium and low power applications. In brushless motors are used to pick and place robot, object to assign particular positioning and actuation applications. The voltage source inverter (VSI) used for obtaining the electronic commutation of BLDC motor for reducing conduction losses and switching losses. The zeta converter operates in discontinuous mode of operation. The proposed zeta converter to provide regulated DC voltage for BLDC motor and to reduce source current total harmonic distortion (THD) at AC mains. The speed of BLDC motor has been controlled by varying the DC-link voltage of VSI and compare between both diode bridge Rectifier (DBR) and bridgeless converter of the BLDC motor drive.
