航空用三次谐波电流注入有源滤波电路的分析与设计

Third-harmonic current injection (3rd-HCI) active filter circuit could be utilized to eliminate low-frequency harmonics generated by the three-phase uncontrolled rectifier. However, some problems exist when the circuit operates in the 115 Vrms/400 Hz aircraft power system. The inductor in the 3rd-HCI active filter circuit is not strictly volt-second balance in one switching period, resulting in in...
