Method for managing a load supplied by a converter that is itself supplied by a battery, and corresponding system
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.
1. A method for managing a load supplied by a converter that is supplied by a battery comprising modules that can be switched, a capacitor being placed between the battery and the converter, comprising:
detecting a switching command;
supplying, via the converter, a lower power to the load when the switching command is detected;
carrying out the switching;
supplying, via the converter, a normal power to the load when the switching is carried out,
in which the converter supplied by the battery is the only converter supplying the load, and
in which a switch placed between the capacitor and the converter is opened so as to supply a zero power to the load.
2. The method as claimed in claim 1 , in which a plurality of switches of said converter are opened so as to supply a zero power to the load.
3. The method as claimed in claim 1 , in which the load is an electric machine of an automobile vehicle powertrain with electric or hybrid drive.
4. A system for managing a load supplied by a converter that is supplied by a battery comprising modules that can be switched, a capacitor placed between the battery and the converter, comprising:
means for detecting a switching command; and
means for supplying a low power to the load which are controlled by said means for detecting a switching command, said means for supplying a low power to the load being configured for supplying a zero power to the load; and
a switch placed between the capacitor and the converter.
5. The system as claimed in claim 4 , in which said means for supplying a low power to the load comprise means for opening a plurality of switches of said converter.
6. An automobile vehicle, comprising:
an electric or hybrid drive comprising an electric machine of a powertrain forming a load; and
the system as claimed in claim 4 .
7. A method for managing a load supplied by a converter that is supplied by a battery comprising modules that can be switched, a capacitor being paced between the battery and the converter, comprising:
detecting a switching command;
supplying, via the converter, a lower power to the load when the switching command is detected;
carrying out the switching;
supplying, via the converter, a normal power to the load when the switching is carried out,
in which the converter supplies a zero power to the load, and
in which a switch placed between the capacitor and the converter is opened so as to supply a zero power to the load.
