A full-wave diode rectifier is fed from a 50-Hz, 220-V rms source whose series inductance is 12

Question:

A full-wave diode rectifier is fed from a 50-Hz, 220-V rms source whose series inductance is 12 mH. It drives a load with a resistance 8.4Ω which is sufficiently inductive that the load current can be considered to be essentially dc.

a. Calculate the dc load current I_dc and the commutation time t _c.

b. Compare the dc current of part (a) with the dc current which would result if the commutating inductance could be eliminated from the system.
