CONTROL OF MODULAR MULTI-DUAL ACTIVE BRIDGE CONVERTERS FOR INTEGRATED SHIP-BOARD POWER SYSTEM
Abstract
Approved for Public ReleaseModular multi-dual active bridge converters based on SiC devices, with coupling high-frequency transformers, are proposed for the Navy shipboard electrical distribution systems. The topological modularity enables the interchange and decoupled control of loads and sources and enhances plug-and-play possibilities, with a high system efficiency of energy conversion, inview of zero voltage switching and the low switching loss of the SiC devices.System modeling and computer and digital real-time simulations of a multi-converter, multi-source and multi-output load distribution system will be undertaken, which in addition to the study of the optimal power flow, will reveal the intrinsic opportunities and challenges of the distribution system. The electrical loads and power sources on the Navy shipboard power systems are dynamic and time changing, with pulsed and propulsion loads requiring fast dynamic responses. This work leverages first on the mild coupling between adjacent dual converters of the proposed topology anduses the concepts of exact decoupling feedback linearization. A decoupling controller structure is also proposed that enables the decoupled control of the loads and sources and provides an agile control to highly dynamic loads.Apart from the computer and real-time simulations using the RTDS facilities, which enable the study of the medium power (MW) system, a laboratory-scale hardware systemwill be built for the exploration and validation of the proposed work.
