This paper introduces a new modular cascaded multilevel inverter (MLI) which is composed of a cascaded connection of submodules (SMs). The combination of basic cells (BCs) with polarity changer H-Bridge produces the SMs, which is the basis of the int

The safety of converters is key to the stable operation of AC/DC hybrid power grids after AC faults. Thyristor valve current is a direct manifestation of the converter observability, but there are no measuring elements inside the converter, so the th

Dual-inverter fed open-end winding PMSM (OW-PMSM) drive topology can extend the speed range under limited DC bus voltage, but it suffers from the zero-sequence current (ZSC) problem when with common bus configuration. Predictive current control (PCC)

Frequency Response Analysis (FRA) is a comparison based method and is useful to identify the mechanical fault in transformer winding only when the ‘healthy’ or ‘reference’ magnitude response is available. But, in practice, ‘healthy’ respo
