Application of Modular Multilevel Converters (MMC) Using Phase-Shifted PWM and Selective Harmonic Elimination in Distribution Systems
<p>Reducing the size and weight of a power electric system is a prodigious challenge to researchers as the development of the latest technologies emerge in the field of electrical engineering. A similar urge is there to develop a light-weight mobile power substation (MPS) to use in the electric …

Device Voltage Balancing from Device-level to Converter-level in High Power Density Medium Voltage Converter using 10 kV SiC MOSFETs
The electric power system is undergoing a paradigm change on how electric energy is generated, transmitted, and delivered. Power electronics systems which can provide medium-voltage (MV) to high-voltage (HV) output (>13.8 kV ac, > 20 kV dc) with much faster dynamic response (> 10 kHz bandwidth) or …
