Abstract
A coupled inductor type boost DC to DC converter with a single multipurpose magnetic component. The invention includes a conventional switch for converting an input DC voltage to a signal having a time varying waveform. The switch Q1 has a pole terminal connected to a source of input voltage, a control terminal and first and second throw terminals. The single inductive element includes a first winding LN.sub.1 connected between an output terminal of the switch and an input terminal of the converter and a second winding LN.sub.2 connected between the second throw terminal of the switch and an output terminal of the converter. In a first embodiment, the invention further includes a winding LN.sub.3 of the inductive element connected at a first end to the control terminal of the switch which provides a level shifting circuit for shifting the level of a drive signal applied to the control terminal of the switch.
