摘要
针对航空400 Hz三相四线的高功率因数整流器系统进行分析,应用d-q旋转坐标变换控制策略实现输入电流基波与输入电压相位的严格一致,从而达到了输入电流零静差的控制目的,同时通过调整0轴的参考值来实现对输出串联电容的均压控制。最后通过实验验证了理论分析的可行性。
A 400 Hz three-phase four-wire high power factor rectifier is proposed.The input currents are in phase with their respective line voltage,using d-q transformation control.With this strategy,zero static error is achieved.The voltages of the DC-link capacitors are balanced by modulating the reference of 0-axis in the synchronous rotating frame.Both simulation and experimental results verify the validity of the theory.
