SCR AC voltage regulator circuit and Buck AC voltage regulator circuit which are more efficient? Thyristor voltage regulation is achieved by adjusting the conduction angle of the thyristor. Is this method similar to adding an infinitely adjustable resistor in front of the load, which does not dynamically adjust the power according to voltage changes; this method of voltage regulation Is it just by adjusting the "resistance value" and using different resistance values to adjust the dispersed power?

From the description, it only describes a simple circuit that adjusts the value of the variable resistance to adjust the voltage. It is a primary circuit. The more advanced thyristor voltage regulation circuit can accurately adjust the average function. The thyristor voltage regulation Belongs to power frequency.
The switching circuit belongs to high frequency, and the control accuracy is naturally very good.

The thyristor controls the triangular wave input by the trigger set to trigger the thyristor conduction flux, so the output voltage waveform changes. Digital circuits can be used for ac and dc trigger control. Generally, BUCK is more efficient.
