In a full wave converter (M - 2 connection) feeding an RLE load, the peak thyristor current is 15 A. For fully controlled bridge circuit and same load current, the peak thyristor current will be
Options
A. 30 A
B. 152 A
C. 15 A
D.
Correct Answer
15 A
Explanation
In both the connections the output voltage and peak thyristor current are the same. Both are full wave rectifiers.
Once SCR has been triggered the gate has no control. Only external resistance controls the anode current.
10. A single phase half wave controlled rectifier circuit has an R-L load. A freewheeling diode is also in the circuit. When freewheeling diode is conducting the SCR
Options
A. is forward biased
B. is reverse biased
C. may be forward biased or reverse biased
D. forward biased initially but reverse biased afterwards
