Gate Driver Design for 1.2 kV SiC Module with PCB Integrated Rogowski Coil Protection Circuit

Wide band-gap materials, e.g., Silicon Carbide (SiC), allow the realization of power semiconductor with superior performance with respect to the traditional Si-based counterparts. On the other hand they require more stringent short-circuit or over-current clearing time to safeguard the device lifetime. This paper focuses on the analysis, design...

Performance Evaluation of an Electric Vehicle Traction Drive using Si/SiC Hybrid Switches

The parallel connection of a Silicon (Si)-based IGBT and a Silicon Carbide (SiC)-based MOSFET forming a so called hybrid switch (HyS) can be used to exploit the advantageous features of both semiconductor and materials technologies. In this paper, a HyS-based inverter designed for the application of Electric Vehicle (EV) traction is compared to...

Optimal Battery Energy Storage System Sizing for Demand Charge Management in EV Fast Charging Stations

The high pulsating demand of fast charging stations (FCS) may cause monthly demand charges to account for a significant fraction of a station's electric bill. To reduce these costs, demand charge management can be applied to suppress peak power demands at FCSs, also using battery energy storage systems (BESS). This paper proposes a multi...
