Abstract:
The invention relates to a method (40) for controlling an inverter (10) using space-vector pulse width modulation, in particular to control an electric machine (14), said inverter (10) being equipped with a plurality of controllable switches (S) and a corresponding plurality of freewheeling diodes (D) and being designed to provide a polyphase electric current (IU, IV, IW) and a polyphase voltage in the form of current space vectors (I*, U*), in particular to supply polyphase electric current (IU, IV, IW) to the electric machine (14). In said method, the inverter (10) is controlled to establish a plurality of different successive switching states (V0-V7) for the switches (S), and the inverter (10) is switched to an off-load switching state (V0, V7) by means of two switching states (V0, V7), a switch-on time (t0-t7) of the switching states (V0-V7) being varied according to a desired load value (m) for the switches (S) and/or for the freewheeling diodes (D), the desired load value (m) being set according to a temperature (Ts, TD) of at least one of the switches (S) and/or one of the freewheeling diodes (D).
