PEBB-based shunt active power filter for shipboard power systems

The future vision of naval electric distribution systems describes a system capable of supplying an electric propulsion system as well as other demanding loads such as high power pulsed loads. The system must also be flexible and reconfigurable. Such a system, containing numerous power electronic devices, will require appropriate compensation systems to maintain some minimum acceptable level of power quality. In this paper, we propose and implement a power electronics building block (PEBB) based shunt active power filter with digital control for future naval electric distribution systems. Various configurations of the software phase locked loop (SPLL), as well as various harmonic extraction strategies are analyzed by comparing them with respect to their steady state and transient performance.
