A genetic algorithm high power density converter system packing method

Applications of power converters in electric cars and trains are demanding highly integrated systems with reduced size and high reliability. To increase the power density, many advanced power converter systems were developed utilizing the new wide-bandgap semiconductors or implementing high switching frequency. However, literatures rarely demonstrate any method to optimize the layout of the power converter system. In this paper, a genetic algorithm based method is proposed to design the converter system packing. Detailed procedures are introduced. The method has been examined at a three-phase inverter, which verifies its feasibility and efficiency. It could be a major step to improve the overall performance of the converter systems.
