Switching energy converter with reduction of the static bias introduced by a stabilizing ramp

A switching energy converter, including a controllable switch and a control device for generating a control signal for controlling opening and closing instants of the controllable switch, the control device being a control device of type in current mode requiring a current stabilization signal to be applied, the control device including:

• a component delivering a stabilization signal intermittently, by applying said stabilization signal at a predetermined instant which precedes a reference instant;
• and,
• a comparing unit for generating the control signal of the controllable switch from the comparison between a set value signal and a measurement signal, which corresponds to a current flowing in an impedance of the switching energy converter, the intermittent stabilization signal being subtracted from the set value signal or added to the measurement signal before application to the comparing unit,
• wherein the control device further includes a summation unit for adding an average value of the stabilization signal to the set value current before application to the comparing unit.
