| Abstract |
A new structure of high power density and high efficiency low output voltage (3.3V) DC/DC converter is proposed in this paper. The connection in series of two power stages provides optimum performance of the synchronous rectification stage with low overall complexity. The performance of this structure is almost independent of the variations of input voltage, because these variations are absorbed by the pre-regulator. Therefore, the driving voltage applied to the self-driven synchronous rectifiers does not depend on input voltage. The high efficiency obtained (91%) in such a low output voltage converter (3.3V/20A) with independence of the input voltage, allows size reduction in on board converters (OBC) for distributed power systems (DPS). |
