SHORT-CIRCUIT-PROOF INVERTER HAVING A DIRECT CURRENT CONTROL

The invention relates to a converter (2) that applies a high and a low potential (U+, U-) respectively alternately for a number of phases to phase lines (5) via phase units (3) and, as a result, feedsphase currents (I1, I2, I3) into the phase lines (5). The phase currents (I1, I2, I3) are led via a filter device (6) which is arranged downstream of the converter (2), which taps off filter occurrents (IC1, IC2, IC3) via filter capacitors (8) connected to the phase lines, and feeds the remaining parts of the phase currents (I1, I2, I3) to an electric load (9) as load currents (IL1, IL2, IL3). The control device (12) accepts the phase currents (I1, I2, I3). A regulating device (15) of the control device (12) determines the activation signals (S) for the phase units (3) of the converter (2) bymeans of direct current regulation, to which currents (e.g. I1, IC1) flowing at the output side of the converter (2) are fed as actual values, and the associated target currents (e.g. I1*, IC*) are fed as target values.
