Abstract: A control circuit for a switching DC/DC Converter comprising: an input for an indicator signal indicative of an output current level from said converter; a peak detector for detecting and storing a maximum value of said indicator signal; a comparator element for comparing an instantaneous value of said indicator signal with said stored maximum value, and for generating a switching signal when said instantaneous value becomes less than a predetermined fraction of said stored value; reinitializer means for reinitializing said peak detector in response to said switching signal; and means for generating a control signal that switches between a state in which it increases over time and a state in which it decreases over time in response to said switching signal. A control module for photovoltaic generator, the module including such a control circuit, and a photovoltaic generator system comprising a plurality of such modules, each controlling a respective photovoltaic generator.

Abstract: A switching type converter comprising an input stage and an output stage, the input stage comprising an input inductor to which an input DC voltage to be regulated is applied, switching means for directing the current passing through the input inductor either to the ground or to the output stage, and a capacitor mounted in parallel between the output from the switching means and the ground, the output stage comprising an output inductor mounted in series, an output capacitor mounted in parallel, the terminals of which carry the output voltage from the regulator, and an additional inductor connecting the output of the switching means to the output stage and magnetically coupled to the input inductor.
