In this paper, improving method of system efficiency in constant power region for interior permanent magnet (IPM) motor driven using pulse width modulation (PWM) inverter with voltage booster is examined. Proposed control method can adjust the ratio of flux weakening control and DC link voltage control. An effectiveness of proposed control is investigated by experiment. Furthermore, improvement of the system efficiency by using silicon-carbide metal-oxide-semiconductor field-effect transistor (SiC-MOSFET) instead of conventional insulated gate bipolar transistor (IGBT) is evaluated. Finally effectiveness of proposed control on different type motors such as "a small current and high voltage type motor" and "a large current and low voltage type motor" is clarified. The proposed control method can provide benefit to improve the system efficiency for IPM motor drive system in constant power region.
