Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for a pulse-width-modulated control of switching elements of a pulse-controlled inverter, comprising: in a first control mode, providing respective pulses for successive signal periods of a control signal, wherein each of the pulses at least one of: has a uniform start time and a uniform end time within the respective signal period, and is centered within the respective signal period; and in a second control mode, providing a pulse which one of: (a) has a start time at a beginning of a first of the successive signal periods and an end time at an end of a second of the successive signal periods, and (b) has a start time at an end of the first of the successive signal periods and an end time at a beginning of the second of the successive signal periods; wherein, during the second control mode, each of the first and second successive signal periods has either the start time of the pulse or the end time of the pulse. 2. The method as recited in claim 1 , wherein a duty factor of the impulses of the successive signal periods of the control signal is variable. 3. The method as recited in claim 1 , further comprising: switching between the first control mode and the second control mode while the pulse-controlled inverter is in operation. 4. 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 respective pulses for successive signal periods of a control signal, wherein each of the pulses at least one of: has a uniform start time and a uniform end time within the respective signal period, and is centered within the respective signal period; and an arrangement for, in a second control mode, providing a pulse which one of: (a) has a start time at a beginning of a first of the successive signal periods and an end time at an end of a second of the successive signal periods, and (b) has a start time at an end of the first of the successive signal periods and an end time at a beginning of the second of the successive signal periods; wherein, during the second control mode, each of the first and second successive signal periods has either the start time of the pulse or the end time of the pulse.
