一款宇航用高压正激变换器设计

Design of a Aerospace High-voltage Forward Converter

通过一个设计实例,介绍了宇航用高压双管正激拓扑的结构特点及磁隔离反馈设计,提出了一种变压器高效设计流程,同时设计了欠压保护线路,最后采用该方案设计了一款实验电路,满足设计指标要求,验证了设计思路和方案的可行性。

This paper describes the structural features of aerospace high-voltage double-barreled forward topology and the corresponding design of magnetic isolation feedback.It proposes an efficient design process of transformer along with the design of an under-voltage protection circuit.It also reports the verification on a specifically designed demo board,showing the feasibility of the scheme.
