摘　　要：为适应未来雷达天线阵面向轻量化、高效率方向发展的需求,研制了一种为T/R组件供电的高密度、高效率、三路输出的电源模块。文中提出一种结合变压器辅助绕组的供电方式,解决了模块内部的所有控制电路的供电问题;采用同步整流技术,有效提高转换效率;介绍了多路输出互锁保护的设计方法,有效提高模块的可靠性。最后给出了样机的实验数据和波形,验证了该设计方案的正确性和有效性。To fulfill the lightweight and high-efficiency for the future radar antenna array , a kind of three-outputs power supply mod- ule with high-density and efficiency is developed for T/R module. Combining with transformer auxiliary winding, a self-startup power supply scheme is presented. It can supply all the power demand of control function in the power module. Synchronous recti- fication technology is applied to improve the conversion efficiency. A multi-output interlock protection design scheme is introduced which can enhance the power supply reliability. The design strategy is verified through the experimental data and waveforms of the prototype.
