Development of a Resonant Auxiliary Power Supply Control Algorithm and Resonant Destruction Detecting for Railway Vehicles

In this paper, the method and a control algorithm for detecting resonant destruction of auxiliary power supply railway vehicle are proposed. It is essential to reduce weight electric equipment attached lower part because it greatly affects life vehicle, such as wheel bearing. order volume supply, in case windings, high-speed switching should be performed by lowering input voltage. Therefore, using an LLC converter proposed, due device failure The proposed steps down wire voltage buck switching, inverter controlled through converter. addition, ZVS (Zero Voltage Switching) operated minimize loss converter, optimal design tank also detect destruction, detection formulated analyzing current peak value load capacity paper verified simulation experiment.
