In a 3 phase bridge inverter, the gating signals for the three phases have a phase difference of
Assertion (A): The circuit of figure thyristor will conduct for 180° during positive half cycle if it is continuously fired.
Reason (R): A thyristor can conduct only when it is forward biased.
The total number of leads in SCR, DIAC and TRIAC respectively are
A single phase semiconverter is feeding a highly inductive load and has a freewheeling diode across the load. The waveshape of input current is
In the below figure, the load is highly inductive. The firing angle is a for each of the thyristors. The periods of conduction of Th1 and Th2 respectively are
