A Limited Common-Mode Current Switched-Capacitor Multilevel Inverter Topology and Its Performance and Lifetime Evaluation in Grid-Connected Photovoltaic Applications

In this paper, a switched-capacitor multilevel inverter with voltage boosting and common-mode-voltage reduction capabilities is put forth. The proposed synthesized one-half bridge several cells. Due to the common-mode current features, suitable for grid-connected PV applications. addition, an analytical lifetime evaluation based on mission profile of has been presented derive distribution semiconductors. Whereas in inverter, any components failure can bring whole system shutdown. series reliability model used estimate overall system. performance suggested applications verified through simulation results using grid-tied Matlab/Simulink. Moreover, viability feasibility are proven by one kW lab-scaled prototype.
