Abstract :
The proliferation of power electronics has introduced several incompatibilities between electronic equipment and typical variations of utility electric power. One of the most common is disruption of operation of pulsewidth-modulated (PWM) adjustable speed drives due to the transient caused by closing utility capacitors. This article explores the impact on PWM drives of the utility capacitor switching transient. The primary focus is determination of the drive response mechanism by simulation and comparison to actual results. Although only the impact of the transient on PWM drives is investigated, the results also apply to other types of power electronic equipment
