<p>An electronic ballast for a fluorescent lamp with low voltage power supply is composed of a wave filter circuit, a rectifier circuit, a generation and control circuit of high frequency and an ignition circuit of the lamp tube. The output end of the wave filter circuit is connected to the input end of the rectifier circuit. The output end of the rectifier circuit is connected to the generation and control circuit of high frequency and the ignition circuit of the lamp tube. The feedback transformer is put into the output circuit of the generation and control circuit of high frequency <IMAGE></p> |
