DC-DC Converter

DC-DC converters are normally built as 2- or 4-quadrants circuits resonating across a medium frequency galvanic insulation transformer. In terms of control, they can be regulated, to stabilize the output voltage, or non regulated, where the output voltage is directly proportional to the input voltage mutiplied the transformer ratio.
