Abstract
Disclosed is a three phase Vienna converter for converting three phase AC to DC, with active power factor control. Further the control electronics is galvanically isolated from the neutral of the input three phase supply and also from the center terminal of the two series connected output DC filter capacitors. The control circuit is built completely with analog devices to meet stringent electromagnetic interference standards. The converter is capable of operating over a wide range of voltages and frequencies of the input supply voltage.
