摘要：
An AC signal producer comprises a controlling unit, a Class-D switch circuit, and a low-pass filter. The control unit receives a DC signal and produces a PWM control signal via checking reference tables. The Class-D switch circuit receives the PWM control signal and outputs a square-wave signal. The low-pass filter transforms the square-wave signal into the AC signal. Thereby, the defect of using an oscillator and a transformer to perform the DC to an AC function in the DC system is solved by the present invention.
