When three-phase current rectifiers are used in the active front end of the aviation power supply system, the wide input AC frequency (up to 800 Hz) causes a surge of reactive power in the AC filter capacitor, which leads to the reduction of the system power factor. To effectively reduce the filter capacitor current, a mathematical model in the synchronous rotating coordinate system is formulated, which is based on the feed-forward decoupling control strategy. The capacitor current is compensated by the phase quantity method. In addition, to further improve the power factor, a power factor current vector coordinated control strategy is proposed to realize the control of reactive current. The control loop and parameter sensitivity are analyzed by using MATLAB, and the zero-pole configuration and gain design scheme of the control loop are given. The model-based development and automatic code generation are adopted to realize the high efficiency of the software part development. Finally, the proposed control method is evaluated by simulation and experiment for its correctness and effectiveness. Experimental results show that the total harmonic distortion rate of the grid-side current is less than 5% and the power factor of the system is always above 0.99 throughout the very wide input frequency.
