摘要：A PWM power regulator device has a processor, an input interface circuit, a zerophase detecting circuit and a thyristor. The input interface circuit is connected to a PWMoutput terminal of an external digital control circuit and the processor. The processorcalculates a period and duty cycle of a PWM signal from the PWM output terminal and

then outputs a triggering signal to the thyristor. The thyristor is triggered at differentconduct angle according to the triggering signal and the triggering signal is determinedby the processor according to the PWM signal. Therefore, the power regulator device isdirectly connected to the PWM output terminal of the digital control circuit withoutdigital to analog converter.
