Abstract:

This work investigates the application of Z-source breaker in multi-zone systems where current is provided to the load through multiple paths. This study is meant to emulate the zonal distribution system planned for future navy ships. Results from detailed simulation as well as development of a low-voltage dc testbed are documented in this report. The motivation behind using dc zonal distribution is to increase the power density on Navy ships. That allows future navy ships to meet their goal of reducing weight and volume hence meeting higher efficiency standards. The future Naval designs will be more compact as a result of this development. A challenge with dc distribution is electrical protection. Z-source dc breakers are one of the options being considered and this work explores the integration of these breakers into dc zonal distribution systems.
