CONVERTER FOR AN ELECTRICAL CIRCUIT DESIGNED TO SUPPLY ELECTRICAL PROPULSION POWER ON BOARD A MOTOR VEHICLE

摘要

The present invention relates to an electrical circuit (900, 900") designed to supply electrical propulsion power on board a motor vehicle, this electrical power being obtained from power delivered to the said electrical circuit (900, 900") by a battery of the said vehicle and converted by at least two cells (901, 903; 901", 903"), comprising inductive elements (902, 904; 902", 904") connected to transistors managing the current flowing in the said inductive elements (902, 904; 902", 904"), characterized in that the inductive elements (902, 904; 902", 904") are coupled so that they form a magnetic circuit (1400) that can be alternatively controlled: - according to a common mode in which an apparent inductance of the said magnetic circuit (1400) is of the order of magnitude of the sum of the inductances specific to each inductive element, or - according to a differential mode in which the apparent inductance of the said magnetic circuit (1400) is of the order of magnitude of the leakage inductance of the coupling between the said coupled inductive elements.
