TL;DR: In this paper, a three-phase single-switch AC-DC flyback power converter system is presented, which operates in the discontinuous mode, and the simple structure of its power and control circuit, low mains current distortion and resistive fundamental behavior as well as the high-frequency isolation of the controlled output voltage are pointed out.

TL;DR: In this article, a thermal model and analytical relations between the hydraulic, electric and mechanical system variables are used to optimize a magnetically levitated pump system aiming for maximum pressure density.

TL;DR: In this paper, a three-phase inverter topology, denoted as Y-VSI, is presented to cope with the wide DC voltage variation of the fuel-cell/battery that supplies the motor drive.

TL;DR: In this article, a three-phase buck-type PFC rectifier with integrated active 3rd harmonic current injection for dc power distribution systems is presented, and the authors show that a peak efficiency of 99% is theoretically and economically feasible with state-of-the-art SiC MOSFETs and magnetic components.

TL;DR: A simple and effective method of driving the new devices with existing monolithic gate drive circuits is proposed by applying a constant negative DC bias to the gate in order to minimize the required voltage swing on the gate to enable switching to take place.
