Abstract : As the Navy progresses into the 21st century, new concepts in shipboard electrical power management are being explored. One area of significant interest to the Navy is utilization of DC electrical distribution systems rather than traditional AC distribution systems. The DC Zonal Electrical Distribution System is a prime candidate for direct application to modem power distribution. This system employs solid state conversion devices to supply ships loads from one of two high voltage DC busses. A new type of control technique known as One Cycle Control has recently been proposed which may be of use in the control of these power converters. Specific advantages of this technique include: (1) no steady state or dynamic error between the control signal and the controlled variable, (2) robust performance, (3) power source perturbation rejection, (4) fast dynamic response to change in the control signal, (5) general switching applications, and (6) automatic switching error correction. The focus of this thesis is to validate the One Cycle Control theory through simulation and testing of a prototype controller.
