Abstract (en)

[origin: WO2020058445A1] The invention relates to a control device (2) for an inverter (1) which comprises three half-bridges (9u, 9v, 9w) each having a first power switching element (11u, 11v, 11w) connected to a first DC voltage potential (10) and having a second power switching element (13u 13v, 13w) connected to a second DC voltage potential (12), wherein the control device (2) is designed to control the power switching elements (11u, 11v, 11w, 13u, 13v, 13w) for converting a DC voltage between the DC voltage potentials (10, 11v, 11w, 13u, 13v, 13w) into a multiphase alternating current in a normal operating mode and for converting the inverter (1) from the normal operating mode into a safe operating mode, wherein the control device (2) is also designed to control the power switching elements (11u, 11v, 11w, 13u, 13v, 13w) alternately for switching single-phase active short circuits and for switching two-phase active short circuits in the safe operating mode.
