Abstract:
A DC/DC voltage converter, comprising:an inductive storage element;a primary controlled switch between a primary source and said inductive storage element; anda secondary controlled switch between said inductive storage element and a secondary source;wherein said DC/DC voltage converter is configured to operate according to a cycle for transferring energy between a primary source and a secondary source,said cycle includes a phase of accumulation of magnetic energy in said inductive storage element from said primary source and a phase of restitution of the accumulated magnetic energy in said secondary source,said DC/DC voltage converter is configured to include an energetically neutral phase in said cycle during which said inductive storage element retains energy therein, said primary and secondary controlled switches are opened, and a zero voltage is maintained across terminals of said inductive storage element, andsaid DC/DC voltage converter is configured such that said energetically neutral phase has a duration within the energy transfer cycle such that said DC/DC voltage converter operates at a predetermined frequency.
