Abstract
A voltage converter is provided comprising a primary circuit which, with an input voltage, is connected through at least one primary winding to at least one respective secondary winding of at least one secondary circuit. The primary circuit and the at least one secondary circuit are tuned individually so that each comprises an oscillatory circuit with coinciding resonance frequencies.
