    • The invention relates to a method for determining phase currents (Iu, Iv, Iw) in an electrical multi-phase system, comprising the following steps: generating pulse-width-modulated switching signals (S1...S6) for switching elements (T1...T6) of half-bridges (H1, H2, H3), wherein the half-bridges (H1...H3) are formed by connecting respective first switching elements (T1, T3, T5) and respective second switching elements (T2, T4, T6), wherein second switching elements (T2, T4, T6) of each half-bridge (H1, H2, H3) are controlled in a manner complementary to first switching elements (T1, T3, T5) of each half-bridge (H1...H3), wherein in the case that rising or falling edges of at least two switching signals (S1...S3) of the first switching elements (T1, T3, T5) are substantially identical, at least one switching signal (S1...S3) of the first switching elements (T1, T3, T5) is shifted to an extent in relation to a substantially identically formed further switching signal (S1...S3) of the first switching elements (T1, T3, T5) in such a way that the edges of the switching signals (S1...S3) of the first switching elements (T1, T3, T5) are not generated simultaneously, wherein a ratio of switch-on duration to switch-off duration of the shifted switching signal (S1...S3) remains substantially constant; measuring a total electrical current (I) at least twice, at defined times (t1, t2) at which at least one switching signal (S1...S3) of a first switching element (T1, T3, T5) has an electrical potential different from at least one further switching signal (S1...S3) of a further first switching element (T1, T3, T5); and determining the phase currents (Iu, Iv, Iw) from the measured total current (I).
