Research on an Electro-Mechanical Hybrid Power Controller

Abstract:

Electro-mechanical hybrid power controller (EMHPC) is a kind of switch with a breaker as mechanical switch and an insulated gate bipolar transistor (IGBT) as solid-state switch. It is a key element of electrical load management center (ELMC) of the more electric aircraft (MEA). On the condition of high voltage (270VDC) and large current (200A), the proposed EMHPC in this paper features great simplicity and reliability. It has no contact chatter when the controller is turned on or off, main circuit will be shut down when contactor fault happens, it also has the feature of over-current protection for solid state switching device when large current occurs in the working circuit. The proposed controller is supported by experimental results.
