In this paper a DC-link voltage balancing strategy for multilevel
Cascaded H-Bridge (CHB) converter is proposed. Presented solution bases on
optimal choice of active vector durations in Space-Vector Pulse Width
Modulation (SV-PWM). It makes it possible to DC-link voltages control and
to properly generate the output voltage vector in the case of DC-link
voltage unbalance. Results of simulation and experimental researches on
proposed control strategy are presented in the paper.
