states the following:

The ripple current from the main and from the load has to be known. First

calculate the capacitor voltage charge time.

tc = [arccos (Umin / UMax)] / [2 x 3.14 x fmain]

Then it give an example:

tc = [arccos (359 / 361)] / [2 x 3.14 x 50] = .000335

I have to be missing something, because I can't get the same answer as they

do in the example. I get tc = 0.0192, which is not right. Can someone tell

be what I am doing wrong?

Thanks,

Brian
