Efficiency analysis of pumps drives for Space Vector PWM and Hysteresis Band PWM with on operation transaction of the control method


An increasing number of electrical motors are driven from frequency inverters. The losses in motor are increased because the produced nonsinusoidal stator voltages, supplied from IGBTs, contain significant harmonic components. Different PWM Methods cause different voltage harmonics. Depending on the control method, the motor characteristics and the partial… (More)
