Patent ID: 7079403

Claim:
An isolated DC-DC converter for use with a DC power source having a DC voltage across a first voltage source output and a second voltage source output and with a load, the converter comprising: a. an input for accepting the DC voltage, the input having a first voltage input and a second voltage input, b. an output electrically isolated from the input for outputting a converted DC voltage, the output having a first voltage output and a second voltage output, c. a primary side circuit connected between the first voltage input and the second voltage input including a first primary winding of a first transformer and an auxiliary section, d. a plurality of rectifier circuits, each rectifier circuit having a separate secondary winding of the first transformer, the rectifier circuits connected in parallel with one another and with the output, and e. an output capacitor connected between the first voltage output and the second voltage output and across the rectifier circuit wherein an output converted DC voltage between the first voltage output and the second voltage output has the same polarity as a DC voltage input between the first voltage input and the second voltage input, wherein the auxiliary section is for causing the first transformer to transfer power from the first primary winding to the secondary winding and to operate without saturation, wherein the rectifier circuit is for converting output of the secondary windings into a one-direction waveform and convening the one-direction waveform into a DC voltage, and wherein the output capacitor is for filtering the converted DC voltage.
