When a high current is needed, SCRs are connected in parallel.
The problem with paralleled SCRs is, when they are not perfectly matched, one will conduct first before the other and carries the full-load current that is for sure greater than its maximum rating.
To avoid this situation, both SCRs should be turned ON at the same time.
How can we do this?
A. by using high triggering gate voltage
B. by using a gate-triggering transformer
C. by using reactors
D. all of the above are possible
