Power Electronics The turn-on time of an SCR with inductive load is 20 µs. The puls train frequency is 2.5 KHz with a mark/space ratio of 1/10, then SCR will Turn on if pulse frequency us increased to two times. Not turn on. Turn on if inductance is removed. Turn on. Turn on if pulse frequency us increased to two times. Not turn on. Turn on if inductance is removed. Turn on. ANSWER DOWNLOAD EXAMIANS APP
