Flying Capacitor Converter as a wind turbine interface - modulation and MPPT issues

Investigation of power converters for AC and DC power collection in wind turbine systems

“…Replacing the clamped diodes in NPC converters with capacitors gives us the multilevel converter topology called flying capacitor (FC) converter [70][71][72]. FC converters are simple in configuration and bring in the advantage of easier dc-link voltage balance and redundant switching states [73].…”
