Power Electronics A thyristor string is made of a no. of SCR connected in series and parallel. The string have volume and current of 11 KV and 4 KA. The voltage and current rating of available SCRs are 1800 V and 1000 A. For a string efficiency of 90 % let the number of SCRs in series and parallel are a and b respectively. Then the value of a and b will be 6, 4. 4, 6. 7, 5. 5, 7. 6, 4. 4, 6. 7, 5. 5, 7. ANSWER DOWNLOAD EXAMIANS APP
