How many thyristors does we need in half wave converter?(a) 1(b) 2(c)

1.	How many thyristors does we need in half wave converter?(a) 1(b) 2(c) 3(d) ManyI got this question during an interview.My query is from DC Motor Control Through Converters in division Motor Control by Static Power Converters of DC Machines
Answer» Right choice is (a) 1 To elaborate: Only ONE thyristor is sufficient for the half WAVE converter purpose, this is employed for small MOTORS only. This thyristor is connected to the single-phase AC supply and with PARALLEL COMBINATION of free-wheeling diode with motor armature.
