Patent ID: 6987676

Claim:
A power converter for use with an alternate current power source and a load, comprising a storage capacitive means for power factor correction, a first transformer and an output transformer, the first transformer comprising first windings, output windings and feedback windings, the second transformer comprising input windings and output windings, the first windings of the first transformer being connected intermediate the alternate power source and one end of the input windings of the second transformer, the output windings of the first transformer being connected to the input windings of the second transformer at an end which is not connected with the first windings of the first transformer, the feedback windings being connected to the output of the second transformer whereby output voltage of the second transformer is fed back to the first transformer, and wherein the storage capacitive means is connected intermediate the output windings of the first transformer and the input windings of the second transformer so that the voltage across the storage capacitive means is dependent on the output voltage of the second transformer.
