摘要
通过仿真和试验分析了DC 600 V客车空调逆变电源某相滤波电容容值衰减或电容失效对输出电压谐波的影响,为检修维护过程中电容故障的识别提供了参考。
The effect of attenuation or failure of filter capacitance a certain phase of the inverting power supply for the air-conditioning on DC 600 V passenger cars,on the output voltage harmonics is analyzed via simulation and test,providing reference for the identification of troubles in capacitors during inspection,repair and maintenance.
