This converter includes a controllable switch (M) and a control device () for generating a signal for controlling the opening and closing instants of the switching switch, the control device being of the control device type in a current mode requiring the application of a current stabilization signal. The control device includes a component () delivering a stabilization signal (RC) intermittently, by applying the stabilization signal (RC) at a predetermined instant which precedes a reference instant; and a comparator () for generating a control signal (CM) of the controllable switch (M) from the comparison of a set value signal (&#xce;L) and of a measurement signal corresponding to the current (IL) flowing in an impedance (L) of the converter, the intermittent stabilization signal (RC) being subtracted from the set value signal (&#xce;L) or added to the measurement signal before applying the comparator.

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

A converter comprising a switch and a control device in 'peak charge' mode for generating a command of the switch, and which comprises an error corrector between an output voltage and a reference voltage, a comparison means between a reference charge and a measured charge resulting from the time integration of the current circulating in the switch to develop the command signal, the error signal at the output of the error corrector being a reference power, the control device comprising a conversion unit comprising a divider dividing the reference power by the input voltage to obtain the reference charge.

Switching power converter with a maximum current mode control

An electric power supply system, comprising: The auxiliary switching cell () comprises at least two switching capacitors (C, C) positioned parallel to one of the secondary switches (T, T) for one of them and parallel to one of the main switches (T, T) for the other one. An aircraft comprising at least such a power supply system.
