This paper proposes a power compensation control for open-end winding interior permanent magnet synchronous motors (OEW-IPMSMs) driven by electrolytic capacitor-less dual inverters with single-phase power supplies. The dual inverter operates with both high-power factor of a single-phase source and a constant torque of the motor. In addition, the additional inverter compensates for a reactive power of the motor, which allows the original inverter to operate at unity power factor condition, thus extending the motor operating region. Simulations and experimental results verify the effectiveness of the proposed power compensation control and extending the motor operating region.
