Abstract
The present invention relates to a switched power converter system (1), comprising at least a first power converter (2) and a second power converter (3). Each power converter (2, 3) has a corresponding input terminal (4a, 5a) and output terminal (4b, 5b), where each power converter (2, 3) comprises a corresponding switch arrangement (6, 7). The system further comprises a control unit (8) that at least at start-up is connected to each power converter (2, 3) in the system (1) and arranged to control each switch arrangement (6, 7) by means of spread spectrum modulation, such that cross correlation between the conducted or radiated emissions of the switch arrangements (6, 7) is avoided.
Claims6
A switched power converter system, comprising:
- at least a first power converter and a second power converter, the first power converter comprising a first input terminal, a first output terminal, and a first switch arrangement, the second power converter comprising a second input terminal, a second output terminal, and a second switch arrangement and
- a control unit that, at least at start-up, is connected to the first power converter and the second power converter, and sends a first pseudo-random code sequence to the first power converter and a second pseudo-random code sequence to the second power converter, the first pseudo-random code sequence being configured to avoid cross correlation with the second pseudo-random code sequence.
