$d_v / d_t$ Protection Circuit of SCR
1 Answer
| written 7.8 years ago by |

When forward voltage is applied across anode and cathode of an SCR, Junction $J_1 $, $J_2$ are forward biased but junction $J_3$ is reverse biased and act as a capacitor. Then the charging current is given by
$$i = \frac{d_q}{d_t}$$
Where q is the charge and it is given by …
