MOSFET Technology as a Key for High Power Density Converters

The rapidly increasing computation-capability, data-density and functionality of electronic systems are the driving forces for high-efficiency high power-density converters. Electronic systems are continuously increasing the demand for power, while simultaneously available space and cooling capability stays constant. This requires smaller form factors of the individual converter, higher efficiencies and higher output powers. To meet these demands, new power architectures, new converter-topologies and new MOSFET technologies are developed. In this paper we will review the basic operational modes for low-voltage semiconductors and mirror the resulting requirements with the capabilities of recent MOSFET technology developments.
