Fault Prediction of Power Electronic Devices in Mobile UPS System

As a source of emergency power supply, the safety and reliability of mobile UPS system has an important impact on the quality of the power supply. Power electronics are the core components of UPS system, and the failure of power electronic device will have a serious impact on the safe operation of the system. Therefore, to improve the reliability of UPS system and reduce the losses caused by component failure and module failure, failure prediction of power electronic device has an important theoretical research significance and practical value. Hence, power electronic device fault prediction of UPS system is studied based on support vector machine.
