Novel Non-Isolated Bus Converters

With switching capacitor technology, a family of non-isolated bus converter without output voltage regulation can greatly increase efficiency, especially at light load. Without the magnetic component or with tiny inductor, the proposed bus converters can realize about 10X power density than the conventional approach. With these compelling traits, these bus converters can significantly improve the performance of AC/DC and DC/DC of the DPS systems in the computer and telecom applications.
