  • Converter for an electrical circuit designed to supply electrical propulsion power on board a motor vehicle
    Patent number: 9248747
    Abstract: An electrical circuit for supplying electrical propulsion power on board a motor vehicle is disclosed. The electrical power is obtained from power delivered to the electrical circuit by a battery of the vehicle and converted by at least two cells. The circuit includes inductive elements connected to transistors for managing the current flowing in the inductive elements, and the inductive elements are coupled to form a magnetic circuit. The magnetic circuit is alternatively controlled according to a common mode in which an apparent inductance of the said magnetic circuit 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 is of the order of magnitude of the leakage inductance of the coupling between the said coupled inductive elements.
