Which type of SCR AC voltage regulator circuit and Buck AC voltage regulator circuit is more efficient? Thyristor voltage regulation is to achieve voltage regulation by adjusting the conduction angle of the thyristor. Is this method similar to adding a stepless adjustable resistor in front of the load, which will not dynamically adjust the power according to the voltage change; 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 variable resistance value for voltage regulation. It is a primary circuit. The advanced thyristor voltage regulator circuit can accurately adjust the average function. The thyristor voltage regulator Belong to power frequency.
The switch circuit belongs to high frequency, and the control accuracy is naturally very good.

To put it simply, is the SCR more like a resistive transformer or a variable power transformer such as a buck buck circuit.

The thyristor controls the triangle wave input of the trigger set to trigger the thyristor conduction, so the voltage waveform of the output changes. You can use digital circuits for ac and dc trigger control. Generally, the buck is more efficient.
