摘要
选用压电陶瓷变压器升压,PWM开关IC控制,VMOS功率放大电路构成的一种新型霓虹灯电源,效率高,工作性能稳定,工作频率46kHz±5%,输出正弦波电压.
The power supply of new neon lamp is Constitued by a piezoelectric ceramics transformer, a PWM switch IGTL 494 as controling and a VMOS power field effect tube as switch apparatus. The effeciency of transformation is high and the working performance is stable. The operating frequency is 46kHz±5 % and the output Voltage is sine-wave.
