Abstract

The steady-state characteristics of an interior permanent-magnet (IPM) motor driven by a pulse-width-modulation (PWM) inverter with voltage booster are analyzed and the transient behavior is investigated. The PWM inverter with voltage booster consists of a conventional PWM inverter and a voltage booster to control the DC-link voltage. The current trajectory on the i_d-i_q plane is illustrated and the torque, voltage, and current versus speed characteristics are represented. Furthermore, the analytical and simulated results are compared to the experimental results for a 1.5 kW IPM motor and the validity of the analysis and simulation is confirmed by their agreement.
