Figure shows a thyristor with the standard terminations of anode $$(A),$$ cathode $$(K),$$ gate $$(G)$$ and the different junctions named $$J1, J2,$$ and $$J3$$. When the thyristor is turned on and conducting

The uncontrolled electronic switch employed in power electronic converters is

The $$MOSFET$$ switch in its on - state may be considered equivalent to

In a commutation circuit employed to turn off an $$SCR$$, Satisfactory turn-off is obtained when.
