Modular Isolated MVDC Power Converters Incorporating WBG Technology
Abstract
The proposed work is to evaluate modular converter designs for their effective use inMVDC ship power systems. This evaluation will consider a great amount of details includingexact topology, isolating transformer design, switch count, converter layouts, switching patterns,and gate drive selection for reduction of EMC issues.Based on a notional ship power system, two locations for MVDC power conversion will beassessed; one at the megawatt power level and one at the tens of megawatts power level. Thelower power level could be a bi-directional application. A set of candidate power conversiontopologies will be selected based on modular topologies involving the dual active bridge,modular multilevel converter, and modular load resonant converter. Each topology will beevaluated at a high level in terms of features such as ease of implementation and effectiveness.This evaluation will occur for application at both locations in the ship MVDC system. Next,each converter case will be specifically designed with WBG devices. The designs will beoptimized to minimize the number of semiconductor devices required and carried out in detailincluding unique layouts which are specific to each topology. A comparison will be done interms of fault tolerance, power quality, manufacturability, and EMC. The proposed work will becarried out over three year. The project will be carried out following the tasks below. The finaldeliverable for this project will be a report which outlines practicality of using WBG devices inMVDC power converter designs.
