TL;DR: FanFan scaling laws are employed in this article to describe volume and thermal resistance of an optimized cooling system (fan plus heat sink), resulting in a single compact equation dependent on just two design parameters.

TL;DR: In this paper, the potential of the multi-cell approach for power electronic converters with efficiencies and power densities beyond the barriers of state-of-the-art systems is discussed.

TL;DR: In this paper, a new strategy for indirect matrix converters which allows an optimal control of source and load currents is presented, which uses the commutation state of the converter in the subsequent sampling time according to an optimization algorithm given by a simple cost functional and the discrete system model.

TL;DR: In this paper, an innovative DC-DC converter is investigated which provides electrical power to the gate driver units of medium voltage level converters, which is achieved with a coreless transformer in order to obtain a cost effective solution.

TL;DR: This paper demonstrates how semiconductor technology, chip area, magnetic component volumes and switching frequency can be selected based on life cycle cost, using analytical and numerical optimizations.
