摘要
介绍了一种正弦波功率信号源电路,该电路用高速双路PWM控制器UC3825为控制芯片,功率MOSFET为开关器件而构成的推挽逆变器,逆变器输出经高频LC滤波后输出I MHz/100W正弦波功率信号。实验证明电路产生的波形质量好,电路结构简单,控制方便,并具有体积小。
It is introduced the sinusoidal power message source circuit, in which high speed double channel FWM controller UC3825 and power MOSFET as power switching device are used to form a pull-push inverter. The output of the inverter is filtered through a high frequency LC circuit and 1 MHz/100 W sinusoidal power signal can he obtained. Kxperimnets show that good waveform can be generated by this circuit. Besides, it also has advantages of simple circuit structure, easy control. small size and high efficiency.
