In this study, the control algorithm for the power distribution units of the high-power devices mounted on the vehicle. High-power system is applied EV / HEV / FCV vehicles with motors, inverters, LDC, HDC, BESS representative. Things about how to manage interoperability between each system has a sequence control, communications, power, etc., the necessary elements for the core components. In particular, this study is intended to supply voltage, current, power, through the observation of the appropriate element in the stabilization. When the system is unstable occurs fault , through the connection of the key components in high-power systems, and that is required to respond to the situation, and present a sequence of algorithms and for appropriate controls and verification through simulation was performed.

Rig test that test the performance of mechanical and electrical devices are applied to shorten the aircraft development period, reduce costs, and ensure quality. This study proposed a method of verifying the power design using rig test to develop an aircraft electrical system. The power design is divided into four modes : normal mode in which power is supplied under normal interfaces with all components, abnormal mode in which power is normally supplied to all power buses from another normally operating component if one component fails, emergency mode in which battery power is supplied to the essential power bus for flight safety if all generators fail, fault isolation and reset mode for fault isolation in case of overloading of components. To verify the power design for each operating mode, it was verified through rig test that the aircraft power requirements specified in MIL-STD-704F, the military standard of the Ministry of National Defense applied during aircraft system development. The rig system was constructed by electrical system components such as power supply, power distribution, power conversion, battery, and various test devices such as DC/AC loaders. By identifying test items for each operation mode and conducting comprehensive system interface tests, it was possible to verify whether the power requirements were met under normal, abnormal, and emergency operating conditions and the interface stability between components through fault isolation and reset tests.
