A voltage commutated chopper circuit, operated at 500 Hz, is shown below.

If the maximum value of load current is 10 A, then the maximum current through the main (M) and auxiliary (A) thyristors will be

1. i _{M max} = 12 A and i_{A max} = 10 A
2. i _{M max} = 12 A and i_{A max} = 2 A
3. i _{M max} = 10 A and i_{A max} = 12 A
4. i _{M max} = 10 A and i_{A max} = 8 A

Correct Option: A

i_Amax = I_o = 10 A
