Problem 62-6
Source: Problem elaborated by the author of the site.
A half-wave rectifier has a rectified voltage VCmax = 30 V. The ripple factor counts r = 5%. Calculate the value of the maximum load that the circuit can supply
using C = 2 000 µF.
(It's the same problem as before, but now let's use RMS ripple, to analyze the difference between
the two types of ripple)
Solution of the Problem 62-6
With the values provided we can calculate the value of Vr (rms), using the eq. 62-11 , reproduced below:
Using the eq. 62-15, and rearranging the terms, we can calculate the value of RL, that is, the value of the load that the circuit supports for the ripple (rms) is not greater than
0.05. Recalling the eq. 62-15, we have
Then, rearranging the terms, we obtain:
