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?
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
