Abstract

An electric energy converter generates a first output signal (S1) and a second output signal (S2) and includes switching elements (10), the converter including at least two bridge arms (10a, 10b, 10c) adapted to generate the first output signal (S1), with a transformer generating the second output signal (S2) simultaneously with the first output signal. The bridge arms (10a, 10b, 10c) are controlled such as to generate the second output signal (S2), the second output signal (S2) being a function of a midpoint voltage equivalent to the sum of the output voltages (E₁, E₂, E₃) of the bridge arms (10a, 10b, 10c) in relation to a midpoint of the input voltage at the switching elements (10). The use thereof in a train is also described.
