Medium Voltage Three-level Converters for the Grid
... Power electronic converters in MV are generally realized as multi-level (ML) voltage source converters (VSC) instead of 2L-VSCs in order to improve the figures of switch power losses, harmonic distortion, dv/dt, and common mode voltage/current [5]. In the literature, there are three main ML-VSC topo ...
