Abstract
A method is described for the pulse-width-modulated control of switching elements of a pulse-controlled inverter, the impulses of successive signal periods of the control signal, in a first control mode, respectively having a uniform start or end time within the signal period, or being situated uniformly centered in the middle of the signal period, and the impulses of successive signal periods of the control signal, in a second control mode, being situated alternately at the beginning of the signal period and at the end of the signal period.
