Abstract
The use of semiconductor devices as a component of eco-friendly motor vehicles has increased and their widespread use as high voltage switches is expected. On the other hand, in the case of high-voltage switches, reliability test equipment is not localized. To test high voltage switches, this paper analyzed the relevant test standards for developing power supplies. In particular, for the automotive semiconductor reliability test, the AEC (Automotive Electronic Council) Q101 was analyzed. Based on that, the standard specifications of the power supply were determined. For the main power circuit, the pull bridge converter was adopted and based on the specification, the circuit parameters were determined and verified by simulation. The interface for the parallel and pattern operation was designed. The characteristics of the power supply were tested.
