Abstract: A method and system manages a load supplied by a converter that is supplied by a battery including modules that can be switched, a capacitor being placed between the battery and the converter. The method includes detecting a switching command, supplying, via the converter, a lower power to the load when the switching command is detected, carrying out the switching, and supplying, via the converter, a normal power to the load when the switching is carried out.

Abstract: An electronic converter allows a power transfer from an AC voltage source, connected between an input terminal and a common terminal, to a load connected between an output terminal and a reference terminal, the AC voltage including positive alternations interspersed with negative alternations at a first frequency. The converter includes an input inductance connected to the input terminal; an output inductance connected to the output terminal; a storage capacitor between the inductances; a chopper circuit that: in a first state, charges the input inductance via the AC voltage source and discharges the storage capacitance in the output inductance by supplying the load; in a second state, discharges the input inductance in the storage capacitance and discharges the output inductance by supplying the load; and a device for controlling the chopper circuit to activate, during each alternations, consecutive operating cycles at a second frequency higher than the first frequency.
