Abstract

This paper aims to study the energy losses in Grid Side Converters (GSCs) used for grid connection of DC residential distribution systems, including renewables and storage. Two different electrical architectures have been considered, the former using an H-bridge as GSC and the latter a PFC active rectifier in association with a storage system. An observation time of one year has been fixed. The analysis is based on the same amount of energy generated by renewables and load demand, in both cases. A detailed formulation of the power losses in each component of the power converter is given. A comparison of the energy lost yearly in both the GSCs is presented, considering different sizing of the storage system.
