Claim Text:
1. A circuit for charging a battery and for driving a three-phase electrical machine comprising at least three static inductors in wye configuration having a first charging terminal connected to a center point, the circuit comprising: a three-phase DC to AC converter comprising a plurality of 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; a first rectifying element and a second rectifying element connected in series to one another; and a second charging terminal provided between the first rectifying element and the second rectifying element; wherein the series of the first rectifying element and the second rectifying element is connected to the DC to AC converter parallel to the DC terminals, and the first rectifying element and the second rectifying element have the same orientation as at least two of the rectifying elements of the DC to AC converter so as to form a full-bridge rectifier with the rectifying elements of the DC to AC converter for rectifying an alternating voltage applied over the first charging terminal and the second charging terminal to provide a rectified voltage between the two DC terminals; wherein the circuit during charging of the battery is configured such that a first, a third and a fifth of the switches operate simultaneously, and a second, a fourth and a sixth of the switches operate simultaneously to ensure that the current through each of the three static inductors is substantially the same at each moment in time.
