What is Class A commutation of Thyristors?

Class A is one of the frequently used thyristor commutation techniques. If thyristor is triggered or turned on, then anode current will flow by charging capacitor C with dot as positive. The second-order under-damped circuit is formed by the inductor or AC resistor, capacitor, and resistor. If the current builds up through SCR and completes the half-cycle, then the inductor current will flow through the SCR in the reverse direction which will turn off the thyristor.
After the thyristor commutation or turning off the thyristor, the capacitor will start discharging from its peak value through the resistor in an exponential manner. The thyristor will be in reverse bias condition until the capacitor voltage returns to the supply voltage level.
