This paper proposes a new 11-level high step-up switched-capacitor based inverter topology. The suggested topology uses only one DC source and can produce a gain of 5. Also it can produce high ratios of steps per switches, gate driver circuits and DC sources, which leads to less devices, less volume, weight and expense. The Total Harmonic Distortion (THD) of produced voltage is low. So, the size of output filter can be reduced. Also, the suggested structure can be well applied on supplying low power factor $R-L$ loads. Natural voltage balancing of capacitors is another main merit of suggested structure that results in simple and easy control strategy. The suggested configuration has been introduced and its operational modes have been explained. Then it has been compared with novel similar topologies and simulated in MATLAB-SIMULINK. The comparison and simulation results confirm the appropriate features and proper operation of suggested configuration. |
