Abstract
The invention relates to a method for actuating inverter stages () switched in parallel, wherein each inverter stage () comprises several switching elements () with two switching states each. In accordance with the invention, the actuation of the inverter stages () occurs via a central control unit () which is connected to each inverter stage () via a serial data transmission path (). Measures are proposed for transmitting the selected switching states from the central control unit () to the respective inverter stage () in order to ensure secure operation of the inverter stages () over a plurality of switching processes on the one hand and to reliably prevent functional impairments of the switching elements () by erroneous actuation, but to also carry out the actuation of the switching elements () of the inverter stages () in a sufficiently rapid way on the other hand in order to avoid impairing the quality of the output current formed by the inverter stage ().
