Abstract

multilevel power converters offer important advantages compared with their classic two-level counterparts. Hybrid neutral point clamped converter with capacitor cells, particularly an H-bridge topology, may be one of the attractive options. This paper presents an innovative modulation strategy providing natural voltage balancing characteristics for that particular topology. The developed modulation strategy shows proper balancing dynamics for the full range of modulation indices. Both MATLAB simulations and laboratory experiment verify theoretical average natural balancing dynamics analysis.
