Abstract In this paper, a digital controlled 400Hz three-phase four-wire PWM rectifier with high power factor is designed for an aeronautical AC-DC converter. Static error exists in direct current control strategy due to sinusoidal reference. So space vector control strategy is used in this paper to realize zero-static-error and high input power factor. In three-phase four-wire topology, the output voltage of the series capacitors may imbalance. So the output voltage balancing outer loop in series with neutral current inner loop control strategy is proposed in this paper to realize voltage balance of series capacitors. At last, both Saber simulation results and experimental results verify the validity and feasibility of the control scheme.

Key words： 400Hz three-phase four-wire high power factor zero static error control voltage sharing control
