Hi. Unfortunately, my old transfomer burned ( shouldn't do that hobby...I'm easily distracted). I have to deal with a new one and would like to know if I can use a bridge with a CT the way it's shown on the diagram.
I first thought of a full wave for 300V and voltage doubler for 600V.
I also thought using a bridge to get 600V and start from there with a second line filter in a more "traditional way" with R-C-R-C...
Thanks
Pierre

Merci de ta réponse Yves. J'ai 550V CT en fait.

So, expect 550 * 1.414 = 777V DC off load with a CLC filter.
Try a LC or RC configuration.

Using choke inputs, you can get two supplies, the one off the ct at 1/2 the value of the one from the bridge. The GEC book says you need chokes on both. The 'back' line from the bridge becomes your ground.
Ok... The negative side of the bridge is grounded. Its positive side is used for the 600V supply and the CT becomes the "+" of the 300V supply...Since I intend to use a regulator, I'm not sure it will like that...
Thanks anyway.

You can even get a choke input supply (at 90% of RMS) and a capacitor input supply (at 141% of RMS) from each of them - by adding an extra diode to the cap input path. Four voltages from one CT secondary winding!
Yes, you're probably right but since it's a 21st Century Maida Regulator, I'd ask to Tom before to wire that way.
