Wanting to build a higher powered SE.

Here's a schematic of what I'm thinking about.

I can't make this in PSU designer II. But it should give me ~300 and ~600VDC from a 250-0-250.
It would almost be cheaper to use 2 Anteks, but then I have to enclose them into something.

The schematic above is a Full Wave Bridge, not a doubler.

The Antek transformer has 2 HV windings. It is a 200Vac, not a 200-0-200. (Do not use a 250-0-250, or you will fry the caps or worse.) You need to parallel the Antek's HV windings to get 500ma. There will be no center tap, but you can tap off of the middle junction of the electro-caps to extract the lower voltage, like so:



Here is another example. The transformer has a secondary of 400Vac. It produces 950Vdc. The lower voltage (465Vdc) is taken off of the junction where the electro-caps meet. There is no center tap.

OK now I know where I went wrong.

I've got it now, just that I have 150 pounds of power transformers and I can't use any of them.

I have 150 pounds of power transformers and I can't use any of them.

If you have a 400Vac or a 200-0-200 (allowing the center tap to float), you could use it with a Full Wave Bridge to get 563Vdc. You would need to drop the voltage to 300Vdc for the driver, but FWBs do not require a transformer with the massive current capacity needed with a doubler.

In our hobby, that's what, 5... 6?
