Description

technical field

[0001] The invention relates to an AC power voltage regulating driver, in particular to an energy-saving AC voltage regulating driver without output waveform distortion, in particular to a sine wave AC power voltage regulating driver. Background technique

[0002] The current sine wave AC power voltage regulating device is mainly composed of thyristors, and the thyristors generally have the problems of voltage regulation output waveform distortion and serious harmonic interference in the process of AC voltage regulation. The reason is: thyristors The control electrode of the control pole can only be triggered to turn on, but not to be turned off. After the thyristor is turned on, it can only be turned off when the current of the thyristor is less than the minimum value for maintaining the conduction (automatically shut off when zero crossing in the AC power supply). Due to the working characteristics of the thyristor, it is difficult to technically process th...
