[SOLVED] Thevenin equivalent of a half-wave rectifier Hello folks, I'm trying to wrap my head around the process of reducing a half-wave rectifier (w/ filter) with an AC input into a simple Thevenin circuit with a DC equivalent voltage. My brain seems to be stuck in "but the input is not DC!" mode. What would the equivalent voltage be? I'm thinking it's the mean voltage across the load (assuming an ideal diode, with 0 resistance), but I don't see why it can't be RMS. The output impedance is not as tricky a concept, as it's simply the impedance of the capacitor, but the Thevenin voltage is giving me grief. Thanks.
