I have a predicament. I'm trying figure out the P-P ripple voltage of a Half-Wave rectifier filter, but the only equation I have is: I / (f * C) yet to find the current I need the DC voltage which I don't have yet. The same goes for the DC voltage. I have the equation: VDC = VOUT P – (VR P-P /2) yet I do not have the ripple voltage yet. So my question is, are there any alternate equations that will allow me to find the ripple voltage without the DC voltage, or the DC voltage without the ripple voltage.
