Design of a battery emulator system for testing of grid-connected inverters.

摘要

This thesis presents a battery emulator based on state of the art power electronics used to test grid connected inverters. The proposed configuration makes use of three power inverters that make the recirculation of power possible, thus minimizing testing costs by only drawing the losses in the system from the utility grid. The approach selected can also be used to mimic the behavior of other similar systems like photovoltaic arrays. This work presents the selection, design and hardware implementation of the proposed battery emulator for testing grid connected inverters.
