摘　　要：在军用电子系统中,传统辅助供电电路使系统体积偏大、成本偏高,无法满足某些低成本小型化系统场合。为了解决该问题,本文提出了一种小型化的辅助供电电路,采用自激振荡的方法,可以实现多路不同功能的辅助供电输出,在保证满足系统多路供电电压的需求情况下,有效地减小了系统体积,降低成本。通过对辅助供电电路参数设计、电路仿真及试验分析,验证了此小型化辅助供电电路设计是合理的,并已在航天产品得到应用。In the military electronic system,the traditional auxiliary power supply circuit makes the system larger in size and higher in cost,which can not meet the requirements of some low-cost miniaturization system.In order to solve the problem,this paper proposes a miniaturization of the auxiliary power supply circuit,adopt the method of self-excited oscillation,can realize multipath different function of auxiliary power supply output,under the condition of satisfying the system multipath supply voltage,effectively reduce the system volume,reduce the cost,and through to the auxiliary power supply circuit parameter design,circuit simulation and experimental analysis,it is verified that the design of the miniaturized auxiliary power supply circuit is reasonable,and has been applied in aerospace products.
