Neutral Point Supply Scheme for PMSM Drive to Boost DC Voltage

Abstract

A novel scheme to supply AC motor drive with a boost function has been proposed. Different from the classic scheme for a three-phase two-level inverter, the main idea of this so-called Neutral Point Supply (NPS) scheme is to move the power supply to the neutral point of machine. It allows to have the capability of boosting DC-bus voltage without adding semiconductor components to inverter. The objective of this paper is to make an in-depth study of this scheme through a permanent magnet synchronous machine (PMSM) drive. Firstly, the principle of the NPS scheme is studied. Then the corresponding control strategy is presented. Meanwhile, the RMS phase currents and additional losses in machine are studied respectively. The effectiveness of a NPS scheme for PMSM drive is demonstrated by simulation.
