Abstract:
1. A control device for an electromechanical power converter with two converter terminals, between which in a first operating mode an operating voltage is applied and which in a second operating mode are connected together, the control device comprising: an operating voltage source for providing the operating voltage between a first supply connection and a second supply connection, controllable switches, by means of which the converter terminals are switched to the first supply connection and to the second supply connection, respectively, a control unit for controlling the switches, wherein the control unit is configured such that a switching load generated by the initiation of the second operating mode of the switches is at least approximately evenly distributed to the switches, and a memory device for storing information including the accumulated switching load of the switches and/or other information, wherein the control unit is further configured to select, if necessary, and based on the stored information, a switch to be switched on for initiating the second operating mode.
