Summary: | Voltage balancing of flying capacitor multilevel converter (FCMC) is one of difficult criterion for the design and using FCMC, particularity with high switching frequency of Wide Band Gap semi-conductor component (SiC and GaN). The aim of this paper is to analyze the voltage-current balancing characteristic of a series-parallel multilevel converter when it is operated under Phase-Shifted PWM (PS-PWM). The natural balancing of open-loop PS-PWM may not be robust and efficiency to keep the converter stable under different transient conditions. Therefore, the paper proposes a closed-loop PS-PWM control method using a voltage and current balancing algorithm. Furthermore, calculations of P and PI controllers are presented for closed-loop control of voltage and current. Simulation results from a three-phase seven-level series-parallel converter are presented. |
