A method for controlling at least one switch in a power converter, wherein the switching speed of the switch dynamically varies according to a measurement of a quantity representative of the efficiency of the converter.

Control of a switch in a power converter

A method and a circuit for controlling a power recovery stage of a plasma display panel including a resonant circuit of at least one inductive element and one capacitive element, wherein the capacitive element is precharged to half a supply voltage of the display panel.

Controlling an energy recovery stage of a plasma screen

An isolated circuit of low-voltage supply of a control circuit of a high-voltage load, in or upstream of a fullwave three-phase rectifying bridge, comprising a first low-voltage capacitor having a first electrode connected to one of the rectified output terminals of the bridge, and at least one second capacitor providing said low voltage, a first electrode of the second capacitor being connected to one of the A.C. input terminals of the bridge, the respective second electrodes of the capacitors being connected by a high-voltage diode having its cathode connected to the second capacitor.
