Three-phase Motor Drive with Bidirectional BPCP Rectifier

摘要

A high power factor three-phase power supply three-phase motor driver with energy feedback is presented. Comparing with the common Blocked Phase Current Patching (BPCP) rectifier, six IGBT or other semiconductor switches, which are connected in a form of three-phase bridge way, are used to instead of the six diodes in the common three-phase bridge, six bi-direction semiconductor switches are used in the lower voltage inter-phase rectifier, and the DC-DC converter is a bidirectional one.
