Ron H said:Right click on the diodes and pick a real diode model. I think the problem is the simplified "D" model has no resistance, so the capacitor looks like a short to the voltage source.
Russlk said:Every node has to have a path to ground, the diode model is probably open at some point. If you put 10 meg in parallel with the diodes, it will most likely work ok.
Spice is both a blessing and a curse. It can lead the inexperienced person down the garden path, or completely confound him (garbage in, garbage out). Speaking of "more complicated designs", we would not be participating in this forum were it not for Spice and other simulators.Nigel Goodwin said:<snip>If it can't be trusted to accurately simulate an extremely simple circuit like a bridge rectifier - how can you trust it with more complicated designs?.
