An Overview of Applications of the Modular Multilevel Matrix Converter
(2020-10-22)
The modular multilevel matrix converter is a relatively new power converter topology
suitable for high-power alternating current (AC)-to-AC applications. Several publications in the
literature have highlighted the converter ...
Comparison of PV-Battery Architectures for Residential Applications
(2016-04-04)
The paper provides a comparison of four PV-battery architectures with dc and ac backbones, in terms of autarky, energy efficiency, battery size and reduction of annual electricity cost. The comparison is conducted based ...
