  "textContent": "A control device () for an inverter () which has a DC voltage input () and a power unit () with three half-bridges () each formed by two power switching elements (), the control device () being arranged to driving the power switching elements () in a normal operating mode for converting a DC voltage applied to the DC voltage input () into a polyphase AC current provided at an AC current output (), wherein the control means () is adapted to evaluate a signal state of a signal () indicating a disconnection of a DC voltage source () from the DC voltage input () and to control the power switching elements () in dependence on a result of the evaluation for alternately adopting a first switching pattern causing DC braking and a second switching pattern causing freewheeling.",
