Abstract:
1. A 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 point and a second voltage input point, b. an output for outputting a converted DC voltage, the output having a first voltage output point and a second voltage output point, c. a high side circuit including a first primary winding of a first transformer and an auxiliary section, the high side circuit directly connected between the first voltage input point and the first voltage output point, d. a rectifier circuit having a first secondary winding of the first transformer, the rectifier circuit connected between the first voltage output point and the second voltage output point, and e. an output capacitor connected between the first voltage output point and the second voltage output point and across the rectifier circuit, wherein an output converted DC voltage between the first voltage output point and the second voltage output point has the same polarity as a DC voltage input between the first voltage input point and the second voltage input point, wherein the auxiliary section is for causing the first transformer to transfer power from the first primary winding to the first secondary winding and to operate without saturation, wherein the high side circuit has one and only one high side circuit output point connected such that current flowing through the first primary winding is directed between the high side circuit output point and the first voltage output point, wherein the rectifier circuit is for converting output of the first secondary winding into a one-direction waveform and converting the one-direction waveform into a DC voltage, and wherein the output capacitor is for filtering the converted DC voltage.
