An Efficient Capacitor Voltage Balancing Scheme for Modular Multilevel Converter Based Wind Energy Conversion System

Modular multilevel converters (MMCs) can be a reliable solution since they have modular structure and high quality output waveform for permanent magnet synchronous generator (PMSG) based wind energy conversion system (WECS). Capacitor voltage balancing in nearest level modulation (NLM) is required...
