Design and Control of Coupled Inductor DC–DC Converters for MVDC Ship Power Systems

Coupled Inductor Design Optimization for Fast-Response Low-Voltage DC-DC Converters

Multiphase voltage regulator modules (VRMs) for microprocessor power delivery with coupled output inductors are discussed. Strong coupling is shown to be feasible and effective at reducing ripple if the correct magnetic topology is used. For more than two phases, this can be a “ladder” core with windings around each rung. Typical ripple reduction is better than a factor of six with no effect on...

Fuzzy Control in Power Electronics Converters for Smart Power Systems

Planar Inductor Design for High Power Applications

Design, simulation, and implementation of low profile microstrip spiral inductors for high power Industrial, Scientific and Medical (ISM) applications at the high frequency (HF-3–30 MHz) range are given for the first time. An accurate analytical model and algorithm have been developed to determine the simplified lumped element equivalent model parameters for spiral inductor and its physical dim...

Control of Power Electronic Converters in Distributed Power Generation Systems

This paper investigates the operation of a currentcontrolled Voltage Source Converter (VSC) under weakgrid conditions caused by large grid impedance. Threedifferent current controller structures are investigated; theconventional decoupled PI-controller in the synchronouslyrotating reference frame, Proportional Resonant (PR)controllers in the stationary reference frame, a...

An End-to-End Simulator for the All-Electric Ship MVDC Integrated Power System

In this paper, a large scale Medium Voltage DC all-electric ship integrated power system is modeled from the prime mover (gas turbine) to the propulsion load. This system has a three-phase 21MW synchronous machine as a main generator and a three-phase 19MW induction motor as a main propulsion drive. The influence of propeller emergence on both electrical and mechanical components of the system ...
