(a) Design of commutating capacitor : The magnitude of the commutating capacitor is dependent on the following circuit parameters:

(i) Maximum load current to be commutated

(ii) Turn-off time of SCR, $t_{off}$

(iii) The battery voltage $E_{\mathrm{dc}}$

The turn-off time $t_{\text { off }}$ of SCR $T_{1}$ is known from …
