A circuit is provided for charging a battery and for driving an electrical machine. The circuit includes at least three static inductors in Wye configuration having a first charging terminal connected to the center point. The circuit also includes a three-phase inverter having switches and rectifying elements, two DC terminals for connecting the battery to the circuit, and three phase terminals for connecting the circuit to the inductors. The circuit also includes a first rectifying element and a second rectifying element connected in series, with a second charging terminal between the first rectifying element and the second rectifying element. The series of the first rectifying element and the second rectifying element is connected to the inverter parallel to the DC terminals and the first rectifying element and the second rectifying element have the same orientation as the rectifying elements of the inverter as to form a full-bridge rectifier.
