Vienna Rectifier

[John626]

I am working on designing a Vienna power supply and am having a lot of difficulty figuring out how to do this. I am an experienced power supply designer. Does anyone have a link or any comprehensive content on how to design a Vienna?

Thanks
John

So I give up; what's a Vienna power supply/rectifier? one approved by Sigmund Freud?

I find it interesting that the only Google hits I find are your questions on the subject, asked on several other forums ...

Is it related to a vienna sausage i.e., just a bunch of baloney?

 

[carbonzit]

Nah, that's more related to Marconi (bologna, dontcha know ...)

Mmmm, Macaroni.

Actually there is such a bridge configuration used apparently in high power designs of power supplies.

I found this snippet. Reads in part:

The Vienna Rectifier is shown in figure 2.

It can also provide sinusoidal input currents and controlled DC-voltage. The control is of comparable effort, and the DC-side neutral point can be stabilized easily (this had been a main concern of engineers).

· Semiconductor blocking voltages reduces by factor 2

· Just three power switches

· Higher efficiency

· You cannot short-circuit the DC by control-failure

· No energy-feedback into the mains possible

Image attached.

I have never seen the design used but then too I don't design high power supplies.
