Modular multilevel converter losses model for HVdc applications [PDF]
Multi-terminal high voltage dc (HVdc) grids can eventually became a feasible solution to transport energy to remote and/ or distant areas and its exploitation depend, among other things, on the performance of the converter terminals.

Self-precharge in single-leg flying capacitor converters [PDF]
Flying Capacitor (FC) multilevel pulse width modulated (PWM) converters are an attractive choice due to the natural voltage balance property. During start-up of the converter, care has to be taken that the power switches are not exposed to voltage ...

Distributed control of a fault tolerant modular multilevel inverter for direct-drive wind turbine grid interfacing [PDF]
Modular generator and converter topologies are being pursued for large offshore wind turbines to achieve fault tolerance and high reliability. A centralized controller presents a single critical point of failure which has prevented a truly modular and ...
