1 Answer
written 4.9 years ago by |
(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 …
