Photovoltaic technology has become one of the leading renewable alternatives for energy production. One main factor in the diminished performance of a photovoltaic module is partial shading, due to the resulting mismatch conditions in the module. However, it is difficult to understand how a specific PV module reacts to shading in comparison with...

The worldwide adoption of Electric Vehicles (EV) has gained momentum in recent years, with more than 30% of all EVs being sold last year. Additionally, a new trend of 800 V battery architectures has appeared to allow for faster charging than the now common 400 V architectures. Future proof charging topologies should, therefore, be able to...
