During operation, the input power is routed through the single-pass path of the buffer device, and is switched on and off several times in each half cycle through the bidirectional switch of the pulse width modulation control device, and the voltage on the excitation side of the transformer is adjusted into several segments. The variable voltage is filtered by the smoothing inductor to make the excitation current waveform of the transformer smoother, and then the voltage on the output side is adjusted through the transformer, and the distortion of the output voltage waveform is improved by the low-pass filter device. [0006] The present invention improves the existing AC voltage stabilizing equipment, the regulation time of the voltage regulation is not fast enough, and the harmonic current causes the power factor on the input side of the power source to be low.
