Abstract
A non-resonant voltage converter includes an inductive element, a primary circuit including a first chopping switch and a first diode in parallel, a secondary circuit including a second chopping switch and a second diode in parallel, at least a smooth switching capacitor of one of said switches, which can form, with a spurious inductance of the inductive element, an oscillating circuit which generates a spurious current. The smooth switching capacitor of the converter is connected in parallel to the terminals of the inductive element, and forms with this element a loop having a reduced length in which is contained the spurious oscillating current.
