摘要： A DC constant voltage circuit comprises a rectifier and a boosting chopper circuit controlled by a general purpose PWM control IC. The general purpose PWM control IC receives a reference voltage Vref which regulates the output voltage by pulse width modulation and produces a voltage having the same waveform and phase as the input current to improve the power factor of the output voltage. An AC constant voltage circuit comprises a common line connecting an AC input terminal and an output terminal, positive and negative boosting chopper circuits for boosting and chopping a half-wave rectified respectively in both positive and negative sides into a DC voltage and a DC-AC inverter for inverting the DC voltage into the AC output voltage. The positive and negative boosting chopper circuits are used as a filter for improving the power factor and adjusting the waveform and phase of the output voltage to be the same as the sine full waveform of the input voltage.
