Abstract

The invention relates to a method for controlling phase currents (iU_WR1, iv_WR1, iw_WR1) of a three-phase inverter (WR1), the phase currents (iU_WR1, iv_WR1, iw_WR1) of the inverter (WR1) being controlled by way of a direct hysteresis current control and a selected phase of the inverter (WR1) being additionally switched depending on a zero system current (i0_WR1) of the inverter (WR1).
