ABSTRACT:
A process for eliminating the disturbances related to fluctuations of the load in chopped power supplies comprising a magnetic circuit with a primary inductance (Lp) coupled to a secondary inductance (Ls), characterized in that it consists in automatically adapting the value of the secondary inductance (Ls) as a function of the voltage (Us) at the terminals of the load (X), so as to ensure total transfer of the magnetic energy for each period of the chopping frequency.
