Abstract

A three-phase dual-output rectifier and its control strategy are proposed for powering airborne low-frequency pulsed load. To address the impact of high peak pulsed power load such as high-power airborne radar on the limited-capacity power supply system of aircraft， a rectifier is designed to simultaneously provide two independently controlled DC outputs. The two DC outputs are used to power the DC bus for the conventional loads and low-frequency pulsed load， respectively， solving the problem of low-frequency pulsed load interfering with the stable operation of conventional loads under the traditional single DC bus power supply architecture. By allowing the DC bus voltage for the low-frequency pulsed load to fluctuate over a wide range， the volume， capacity， and weight of the bus decoupling capacitors are significantly reduced. The paper presents the circuit implementation of the dual-output rectifier， provides a detailed analysis of its operating principles， and proposes a PWM modulation strategy and control method tailored to meet the power distribution and regulation requirements of the two outputs. Finally， experimental results are provided to validate the feasibility and effectiveness of the proposed method.

Key words： airborne power systems; pulsed power supply system; AC-DC converter; dual DC bus; pulsed power decoupling
