Abstract
The AC line current to a fully loaded, three-phase pulse-width modulation (PWM) drive varies with the AC line impedance. The PWM drive consists of a three-phase diode bridge supplying DC power to a bus capacitor and an inverter. The lower the per-phase line inductance, the greater the RMS AC line input current. AC line current peak, and harmonic currents. Results from a computer study that tabulated the RMS current and harmonics are presented. The study considers the effect of reduced line current due to diode current commutation with higher line inductance. Data from a laboratory test set-up are tabulated and confirm the results.<>
