Analysis of Four Switch BLDC Motor Drive for Industrial applications

Abstract

This paper presents the investigation of a practical sensor less control procedure for an ease four-switch, three-stage inverter brushless dc engine drive[1]. Sensor less strategy depends on the discovery of zero intersection purposes of three voltages. An immediate stage current control strategy[1] is utilized to control the stage flows in the four-switch inverter. In four switch brushless dc engine four switches were utilized and henceforth decrease of no of switches in the inverter which will diminish the expense and exchanging misfortunes. Rather than two switches, capacitors [2] utilized. The exhibition of the created sensor less strategy is shown by reproduction.
