摘　　要：机电混合功率控制器是集断路器线路保护功能和固态继电器可靠性于一体的智能开关装置,是飞机负载管理中心的一个组成部分。采用IGBT作为开关器件,设计了一种机电混合式大电流功率控制器,该控制器在高压(270VDC)、大电流(200A)情况下,具有开通关断无触点抖动、接触器故障时关断主回路、出现过电流时对固态开关器件保护等特性。最后给出了实验结果,验证了设计的可行性与正确性。Because electro-mechanical hybrid power controller （EMHPC） a key element of Electrical Load Management Center （ELMC） of the More Electric Aircraft （MEA） is a kind of intelligent switches which incorporate the wire protection function of circuit breaker with the reliability of solid-state relay, this paper designs a new kind of Hybrid Electrical Power Controller with IGBT. On the condition of high voltage （270VDC） and large current （200A）, it has the characteristics of great simplicity and reliability, that is, it has no contact chatter when the controller is turned on or off; main circuit will be shut down when contactor fault happened, it also has the feature of over-current protection for solid state switching device when large current occurred in the working circuit. The proposed controller is supported by experimental results.
