摘要

本文介绍了在100千赫兹开关频率下采用推挽拓扑的10.6瓦EPC的设计与开发。该多输出EPC适用于70±2伏直流输入电压。本设计的突出特点是采用电流模式控制，在所有辅助输出线路中采用低差串联稳压器，以满足严格的线路和负载调节要求，输入EMI滤波器，接口电路用于ON/OFF命令，遥测和EPC频率同步信号。EPC是在两层FR4层压板上制作的，并集成了PLC子系统。最后给出了测试结果，验证了其良好的性能。EPC在-15°C至55°C的极端温度范围内进行了测试和评估，以使EPC符合空间使用要求。

Space grade multi-output 10.6 watt electronic power conditioner with high efficiency

This paper describes the design and development of a 10.6 watt EPC using pushpull topology at 100 kilo Hertz switching frequency. This multiple output EPC is designed for 70±2 volt DC input voltage. Salient features of this design are the use of current mode control, low dropout series regulator in all auxiliary output lines to meet stringent line and load regulation requirements, input EMI filter, interface circuits for ON/OFF command, telemetry and EPC frequency synchronization signal. The EPC is fabricated on two layer FR4 laminate PCB and integrated with PLC subsystem. The test results are shown at the end which shows excellent performance validation. The EPC has gone through test and evaluation sequences over temperature extremes from -15°C to 55°C to qualify the EPC for space usage.
