Abstract
The Department of the Navy is determined to find ways to increase the energy security of shore facilities. This is critical to ensure that facilities can meet fleet needs during a national crisis. An Energy Management System (EMS) using power electronics could be an important piece of this puzzle. In this thesis, a 20-ampere (A)-rated EMS module is designed and constructed that can be used for demonstrations and field testing. The prototype is used to conduct preliminary testing of the EMS over-current trip circuit. This thesis discusses the analog and digital redesigns that are needed to overcome the electromagnetic interference from the switching currents of the power modules that leak into the control circuitry. Finally, a Simulink model is designed to simulate the expected output from the H-bridge portion of the EMS. This model is tested and verified using measurements from the actual EMS prototype in the laboratory.
