Abstract In order to enhance the operation performance of the pulse width modulation (PWM) rectifier under the grid voltage imbalance, the paper proposes an improved direct power control strategy with the resonant regulators to achieve the three selective control targets, including the sinusoidal current, constant active and reactive power, constant DC link voltage and reactive power. Two closed loop controllers are employed in the proposed control strategy to implement the control of the average power and pulsation components under the different control targets respectively for PWM rectifier. And the stable operation capability and anti-disturbance capability of the proposed DPC strategy is also analyzed. Finally, the experiment system of a 1kW PWM rectifier system is developed to validate the availability of the proposed control strategy.

Key words： Direct power control(DPC) PWM rectifier resonant regulator unbalanced grid voltage
