I am building a simple PSU with a torroidal transformer and bridge rectifier. I'd like to know the output DC voltage from the rectifier while under load. e.g. charging a battery. I see that the formula is in here but these things do my head in (sometimes) so if I quote the numbers some kind souuratingl may help.
The transformer is labelled as being 22 VAC at 16.9 amps but at a less than constant duty cycle I fear. It is centre tapped and grounded. At least there's a green etc. ground wire along with the red and yellow secondaries. However, my DVM is registering 28 VAC and the DVM if not Fluke, isn't rubbish no worse than 2-5% I'd say.
Connected to a bridge rectifier rated at 1000 V and current rating > 20 A, what DC voltage should I expect to see with/without a resistive load?
