<p>5 The present invention provides a synchronous regulation circuit forturn-on and turn-off phase angle of the AC voltage, wherein a solid switch unit is installed between an AC power source and a load, and a phase angle regulation circuit is utilized to synchronously regulate both of the turn-on phase angle and turn-off phase angle of the solid switch unit, so10 that the sine waveform voltage of the AC power source can be kept to output in symmetrical waveforms within the range in which the turn-on and turn-off phase angles being synchronously regulated.
