A dc circuit breaker must use
-
In a single phase full wave regulator feeding R-L load, the minimum firing angle can be zero.
-
An RC snubber circuit is used to protect a thyristor against :
-
A single phase semiconverter has a freewheeling diode. If the firing angle is a and the load is purely resistive, the periods of conduction and freewheeling respectively are
-
A dc separately excited motor has a constant field current. The armature is fed from a single phase supply through a semi-converter. When a = 0, speed is 600 rpm. If a = 90°, the speed is likely to be
-
A static induction thyristor
-
A single phase step up cycloconverter changes 50 Hz to 100 Hz. Then one half wave of input will give rise to
