摘　　要：随着卫星的功率需求越来越大,电推进等高压大功率设备在卫星上广泛应用,传统的100 V母线架构难以满足卫星日益增长的需求。提出了一种适用于直驱霍尔电推进设备的高压母线变换模块,采用两级式架构,前级采用交错Boost电路,后级采用全桥升压电路,可以提供300 V的高压母线,同时实现最大功率点跟踪(MPPT)、电流恒流充电和母线稳压等功能。With the increasing power demand of satellites,high-voltage and high-power equipment such as electric propulsion is widely used on satellites,which makes it difficult for the traditional 100 V bus electrical architecture to meet the increasing demand of satellites.This paper proposes a novel high-voltage conversion module for direct-driving Hall electric propulsion equipment.It adopts a two-stage circuit which can realize the functions of Maximum Power Point Tracking(MPPT),constant current charging for battery and bus voltage stabilization.
