In this proposed configuration, traditional leg composed of two power switches 0 引言 was replaced by the novel bridge composed of one power switch and one diode. The annoying shoot-through 现代航空领域中，以电能部分或全部取代其他 phenomenon was eliminated by using this configuration. 二次能源，已经成为现代飞机能源系统的主要发展 Meanwhile, the better efficiency and better performance 趋势[1-3] 。然而，电网系统结构也更为复杂、容量更 brought by this novel configuration benefit the improvement of 高，同时电网中机载设备和电能变换装置也更多， the compensation performance. Moreover, operation principle of the APF was analyzed in detail; current control strategy and 导致飞机电网系统的谐波来源更趋多样化，加剧了 the voltage balance control strategy for the split-capacitor 供电质量和可靠性问题的严重性。为了满足航空领 topology were studied as well. Finally, a prototype with
