Power electronics - Rectifier Problem Help!

[Kenny_2009]

Hello forum members,

I am trying to prepare for my final exam, and I am confused about one of the rectifier problem which might be asked in the final. I would really appreciate if anyone can help me on this!

Here is the problem

Schematic:
I have attched it below


Vs = Vm Sin(wt+ a) (i.e. V3 in the pic)

a = Commencement angle; a>0
β = Conduction angle; β<2 pi

a = the angle in radians at which the source current begins to flow
β = is the angle at which the source current ceases

1. Find i(t) - ( i(t) is the current through tte inductor)

2.At what time does D1 current falls to 0?

3.At what time does inductor current falls to 0?

4. What is the DC current flowing through the source?

5. How much power is delivered to the battery?

6. What is the power factor of the source?

Thanks in advance!
Kenny

Any thoughts?

I have Final exam tomorrow, I would appreciate of anyone could help me here.

I guess...
2. D1 current is zero during negative excursion of the source
4. There is no DC current, both diodes block that dc source

...ah the rest, been too long ago, sorry

Yes it definatley looks like its been a long time for you. lol

Would you like to share your thoughts? what is it that you find difficult about it?
Assuming all the components are ideal there isn't much to learn from this problem (except for the fact that it is highly counter-intuitive).

I may be way off, but I think there are better questions for an exam, this one isn't "educational".

Good Luck with your exam!
