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.

A method for a pulse-width-modulated control of switching elements of a pulse-controlled inverter, comprising:
- in a first control mode, providing impulses for successive signal periods of a control signal, wherein the impulses one of:
- respectively have one of a uniform start time and an end time within each signal period, and
- are uniformly centered in a middle of at least one signal period;
- and
- in a second control mode, alternately situating the impulses of the successive signal periods of the control signal at a beginning of the signal period and at an end of the signal period.
A control unit for a pulse-width-modulated control of switching elements of a pulse-controlled inverter, comprising:
- an arrangement for, in a first control mode, providing impulses for successive signal periods of a control signal, wherein the impulses one of:
- respectively have one of a uniform start time and an end time within each signal period, and
- are uniformly centered in a middle of at least one signal period;
- and
- an arrangement for, in a second control mode, alternately situating the impulses of the successive signal periods of the control signal at a beginning of the signal period and at an end of the signal period.
