What is the difference between an SCR and a GTO?

To determine

Write the difference between silicon-controlled rectifier (SCR) and gate turn-off thyristor (GTO) devices.

Explanation of Solution

Discussion:

The differences between silicon-controlled rectifier and gate turn-off thyristor devices are given as follows:

SCR	GTO
1. Only the ON function is controllable with SCR.	1. Both ON and OFF functions are controllable with GTO.
2. SCR uses only positive pulse.	2. GTO uses both positive and negative pulses...
