Abstract

A power control strategy based on PRN (Proportional Resonant and Inertia) is proposed in this paper. In the motor drive without dc-link electrolytic capacitor, the traditional PI controller is difficult to track the power which contains both ac and dc components. This characteristic cannot meet the system requirement of high input power factor. Therefore, PRN is used in power control. With higher open loop gain in both low frequency and specified resonant frequency, the PRN controller can provide an accurate tracking of the ac and dc power components. Then the input power factor and the phase error between the input current and the voltage can be improved obviously in the drive system. The simulation results verified the high power factor and low THD (total harmonic distortion) of the proposed method.
