一、概述普通铁路客车照明电源是48伏直流电源，照明大部分采用15瓦荧光灯。15瓦荧光灯正常工作电压为交流50伏。由于荧光灯是具有负阻特性的气体放电光源，开始通电工作时需要较高的启辉电压，进入正常工作时。需要把灯电压与灯电流控制在正常范围，因此需要专用消荧光灯逆变
First, an overview Common rail passenger car lighting power supply is 48 volts DC power supply, lighting most of the 15-watt fluorescent lamp. The normal operating voltage of a 15-watt fluorescent lamp is 50 volts AC. Because the fluorescent lamp is a gas discharge light source with a negative resistance characteristic, a high starting voltage is required when starting the energization work, and when entering the normal working time. Need to control the lamp voltage and lamp current within the normal range, so the need for dedicated anti-fluorescent lamp inverter
