2. Modeling and Design of Modular MultilevelConverters for Grid Applications
Abstract : Grid-connected high-power converters are found in high-voltage direct current transmission (HVDC), static compensators (STATCOMs), and supplies for electric railways. Such power converters should have a high reliability, high efficiency, good harmonic performance, low cost, and a small footprint. READ MORE
