Hi all,
I'm kind of stuck for this question, it's asking me to compute the Vav of a half wave rectified sinusoidal AC signal. I am aware that for an ideal diode (with no voltage drop), that would be Vpk / pi, however, the answers I get are not quite correct. For example, I get 2.99 v instead of 2.89 v, or 5.18 v instead of 5.06 v. Where is this extra voltage drop coming from? I assume that it has something to do with the fact that the diode voltage drop causes the conduction period to take slightly less time that the non-conduction period, and that causes the period to drop to just below pi, and then that causes the average voltage to be lower than what it would be in an ideal situation.
Thanks
