摘要

提出了面向机载低频脉冲负载供电的三相双输出整流器及其控制策略。针对大功率机载雷达等高峰值脉冲功率负载对飞机有限容量电源系统造成的影响,设计了能够同时提供2路独立受控直流输出的双输出整流器。整流器2个直流输出分别用作常规负载和低频脉冲负载的直流供电母线,解决了传统单直流母线供电架构下低频脉冲负载干扰常规负载稳定运行的问题。通过允许低频脉冲负载直流母线电压宽幅波动,有效减小了母线解耦电容的容量和体积质量。给出了双输出整流器的电路实现方式,分析了其工作原理,提出并详细研究了适应2路输出功率分配与调控需求的PWM调制策略及其控制方法。最后,通过实验验证了所提方法的可行性和有效性。

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.
