DBSRC变换器开关管开路故障检测策略研究
Research on Switch Tube Open-circuit Fault Detection Strategy of DBSRC Converter
摘要
Abstract
Taking the switch tube open-circuit fault of dual bridge series resonant DC-DC converter(DBSRC)as the research object.Firstly,the basic working principle of DBSRC was summarized,and the open circuit fault characteristics of DBSRC converter were introduced.On this basis,the fault characteristics that can be used for fault detection and localization after open circuit faults in DBSRC converters were analyzed.A fault detection strategy based on resonant capacitor voltage,resonant current,and bridge arm current was proposed for DBSRC converters after open circuit faults.Finally,a simulation model was constructed to verify the effectiveness of the open circuit fault detection strategy for switching devices.关键词
