Integration of the Battery Energy Storage System in a 450 kW EV Charger

Despite the Covid-19 pandemic and supply chain challenges, including shortages of semiconductor chips, the electric vehicle (EV) market is expanding rapidly. Automobile manufacturers have been progressively developing business plans, considering electrification as an opportunity to acquire market share and preserve competitive advantages. The...

Comparison of Two and Three-Level DC-AC Converters for a 100 kW Battery Energy Storage System

This paper discusses a qualitative comparison between Two and Three-Level Voltage Source Converter (VSC) topologies for battery energy storage applications. Three-Level Neutral Point Clamped (NPC) and T-Type circuit topologies are benchmarked versus the state-of-art Two-Level VSC in terms of efficiency and power density considering a 100 kW...
