Abstract
An electronic converter having an input circuit and an output circuit which, in addition to the converter function, carries out power-factor correction. A control circuit opens and closes an electronic switch as a function of the output voltage from the converter circuit and the voltage which is dropped across a current measurement sensor. The circuit has a logic ground LM and a power ground PM at different electrical potentials.
