Abstract (en)
[origin: EP0128988A1] 1. A process for controlling a chopped power supply connected to a supply network and comprising a primary inductance (Lp) coupled through a common magnetic circuit to a secondary inductance (Ls) and supplying a load (X) to which a capacitor (C) is connected in parallel, said process consisting in completely demagnetizing the magnetic circuit for each period of the chopping, characterized in that, to this end, the value of the secondary inductance (Ls) is automatically adapted as a function of the value of the voltage (Us) at the terminals of the load (X).
