AC DRIVES - Rockwell Automation

A modern AC drive power structure consists of three basic stages. It is ironic that while most DC drives run on AC, most AC drives run on DC. This is because the inverter section shown in the "IGBT Inverter Bridge" in Figure 1 requires a stable DC source to operate. Therefore, the first stage of the drive must convert threephase AC to DC.
