Q.1. (A) Determine whether each statement is true or false. 1. Commutation circuitry is simply a class of switching devices connected in series with the SCR. 2. The gate voltage can be set to fire the SCR at two points only in the AC cycle. 3. The SCS has a much lower power capability compared to the SCR. 4. GTO is a very high power device. 5. The switching rate for turning the GTO off is much faster than the SCR. 6. The switching circuitry can also apply a reverse bias voltage across the SCR, which also will turn off the SCR. 7. The SCR is a switching device for high voltage and low current operations. 8. The JFET is a unipolar and a voltage-controlled device. 9. There is direct electrical connection between the gate terminal and the channel of a MOSFET. 10. GTO conducts only in one direction.
