基于单周期控制的机载三相高功率因数整流器研究

摘要

飞机对机载设备的用电特性要求越来越严格，特别是对三相电源的输入功率因数和电流谐波有着严格的要求，此外在电磁兼容试验中对输入电流谐波含量的要求也很高。研究了机载三相三开关三电平整流器，将其等效为三个单相功率因数校正（PFC）电路，分别采用英飞凌单周期PFC控制芯片ICE3PCS02实现了三相功率因数校正电路。仿真与实验结果表明该电路在三相功率因数校正方面有着良好的效果，在中小功率机载雷达电源上具有广泛应用前景。%This paper consider airborne three-phase three-switch three-IeveI rectifier which couId be the equivaIent of three singIe-phase Power-Factor-Correction (PFC) circuits and used the one-cycIe controI ed by ICE3PCS02 respectiveIy.
