Design on the power system of EMC hardware-in-loop experiment platform

Nowadays, EMC has become a serious problem of modern aircraft. In order to simulate and analyze complex EMC phenomenon on aircraft, we chose HILS method to build an EMC test platform. In this paper, we discussed the power system of this platform. Based on requirement analysis, we indicated that the power system should achieve following functions: supplying power for all the devices on the platform, imitating stoppages and EMC problems of real aircraft power supply system. Then we designed details for each component of the proposed system. We also carried out some functional simulation to verify the feasibility of this system.
