Abstract
A switched mode DC-DC power converter of the flyback type includes a primary circuit and a secondary circuit capacitively coupled to one another. In a first aspect the primary includes circuitry for achieving a 2:1 current transfer gain over the input, in a second aspect the secondary includes circuitry for achieving a 2:1 current transfer gain over an input. Combined, a 4:1 current transfer gain may be realized.
