High-performance DC-DC converter

The high power voltage DC-DC converter is a bi-directional multiphase converter for a dual voltage power system. A DC-DC converter for power supply of the conventional 14 V power system in vehicles with 48 V alternator can, for example, support high-performance electric machines for boosting and creeping. Reduced load currents can be used for supplying high power loads at 48 V levels.
