Abstract
A process for controlling a DC/DC voltage converter and a DC/DC voltage converter with inductive storage, operating according to cycles for transferring energy between a primary source and a secondary source. Each cycle includes a period of accumulation of magnetic energy in an inductive element from the primary source, followed by a period of restitution of this energy in the secondary source, wherein an energetically neutral phase of a duration such that the DC/DC voltage converter operates at a predetermined frequency is introduced into the operating cycles.

A DC/DC voltage converter, comprising:
- an inductive storage element;
- a primary controlled switch between a primary source and said inductive storage element;
- and
- a 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, and
- said 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.
