<p>The device (40) has a current generator for generating and injecting current to an input of a converter (28) according to an intensity of a harmonic current measured by an alternative current sensor (44), where the current is greater than the harmonic current measured by the senor. The sensor measures alternate components of the current except for principal component of direct current (DC) current. An independent claim is also included for a traction chain comprising an electric motor.</p> |
