The invention relates to a method for stipulating actuating periods (44) for an inverter (2) having at least two half-bridges (14) comprising two half-bridge switches (16, 17) that are connected to one another via a centre tap (22) and the connections (18, 20) of which have a voltage (10) applied to them with reference to the centre tap (22), wherein in each half-bridge (14) a first (16) of the half-bridge switches (16, 17) can be actuated with a first actuating period (44) from the actuating periods (44) and the second (17) of the half-bridge switches (16, 17) can be actuated with a second actuating period from the actuating periods (44) as part of pulse-width modulation (36), comprising - determination of the actuating periods (44) for both half-bridge switches (16, 17) of both half-bridges (14) during a period (40, 42) of the pulse-width modulation (36), and - alteration of the first actuating period (44) of the first half-bridge (14) in comparison with the second actuating period in the first half-bridge (14) if, within the period (40, 42) of the pulse-width modulation (36), the first actuating period (44) of the first half-bridge (14) and the first actuating period (44) of the second half-bridge (14) are congruent within a predetermined tolerance. |
