A modular switched-capacitor multilevel inverter featuring voltage gain ability

Abstract This article presents a modular switched-capacitor multilevel inverter which uses two capacitors and single dc source to obtain triple voltage gain. It is worth noting that the inherent inversion capacity removes H-bridge, can efficaciously diminish stress of switches, maximum (MVS) on devices kept within 2 V . Additionally, proposed topology able integrate inductive load, capacitor self-balancing be achieved. Moreover, structure also has an expandable generate more levels raise gain by using multiple units, meanwhile power switches Furthermore, comprehensive analysis comparison with other inverters have been implemented certify superiority topology. Finally, steady-state dynamic performance examined through seven-level prototype, validity practicability are verified simulations experiments.
