To eliminate the adverse effects of the low-frequency pulse load with a high peak-to-average power ratio on the periodic impact of the limited-capacity airborne AC power supply system, this paper proposes a three-port power decoupling rectifier which can provide both power decoupling ports and DC output ports through the integration and multiplexing of switching devices. By combining a three-port rectifier with a DC/DC converter, we construct an airborne power supply system integrating low-frequency pulse power decoupling ports, realizing the decoupling of the periodic pulsating power on the DC side and the power on the AC source side, and guaranteeing the normal power demand of the low-frequency pulse load. The working principle of the three-port rectifier is analyzed, and the corresponding power control method and modulation strategy are proposed. Based on the principle of time-division multiplexing of the switching devices, the power transmission and distribution from the AC port to the two DC ports is realized. A smooth transition of the power switching process between the two DC ports is realized. The experimental results verify the effectiveness and feasibility of the proposed three-port pulse power decoupling rectifier.
