Abstract
The invention relates to a method for controlling phase currents (iU_WR, iv_WR, iw_WR) of a three-phase inverter (WR), the phase currents (iU_WR, iv_WR, iw_WR) of the inverter (WR) being controlled by way of a direct hysteresis current control and a selected phase of the inverter (WR) being additionally switched depending on a zero system current (i_WR) of the inverter (WR).
