TL;DR: In this paper, an accurate small-signal model for a galvanically isolated, bidirectional DC-DC converter and the implementation of a corresponding controller on a digital signal processor (DSP) as well as key methods and functions required for the digital implementation are detailed.

TL;DR: In this article, the topology of a new three-phase three-switch three-level PWM rectifier system is derived based on the basic structure of a DC-to-DC SEPIC power converter.

TL;DR: In this article, an advanced modulation scheme is proposed which does prevent the input current distortion and does allow to maintain the optimum performance of conventional modulation schemes for three-phase three-switch buck-type PWM rectifiers where the switching state of one bridge leg is clamped within a /spl Pi/3 wide interval of the mains period.

TL;DR: In this article, the authors derived power and loss scaling laws for EDS systems and compared them with other forms of commercial high-speed ground and air transportation systems, including subsonic airliners.

TL;DR: In this paper, the split ratio of an interior rotor permanent magnet machine was optimized with the goal of generating maximum torque for a given motor volume for that purpose, thermal constraints have to be considered that limit the producible magnetomotive force and, consequently, the torque output Both a maximum local current density in the coils and a maximum global copper loss density related to the motor surface are respected
