Editorial Special Issue on Miniaturized Power Electronics Systems

The eleven articles in this special section explore the technology and applications supported by miniaturized power electronics systems. Power electronics systems have gone through several generations of development during last half century. Its development has been significantly accelerated from late 1980s with the development of power MOSFET due to its superior performance, such as easier use, higher reliability, and higher switching frequency. High switching frequency operation plays a key role in miniaturizing the power electronics system as smaller inductor and capacitor can be used. In parallel, power system architecture, especially the intermediate bus architecture has facilitated this trend by reducing the overall size/board area needed for power system. Although it is by no means exhaustive, this special issue has provided a wide range of new technologies to minimize the size and volume of electronic power systems.
