Design of a ship service converter module for a reduced-scale prototype integrated power system

摘要

A DC Zonal Electrical Distribution System (DC ZEDS) is a strong candidate for the next generation surface combatant, DD-21. In order to equip DD-21 with DC ZEDS, preparative research includes the design of a low-power prototype Integrated Power System (IPS). This thesis examines the design and layout of one element of the IPS, a 500V/400V, 8kW, 20kHz dc-dc converter. The main thrust of the study is the documentation of product construction, design, and ancillary issues. Since the converter will be integrated into a testbed, it must be rugged, transportable, flexible, and provide convenient interconnection and monitoring. MATLAB and dSPACE models and circuit prototypes are implemented to validate subsystem designs and operation. Unit validation studies are conducted to assess performance of the power-section, controls, protection, and interfaces.
