A Novel Multilevel Inverter Based on Switched- Capacitor for High-frequency Power Distribution Applications
نویسنده
چکیده
A novel switched-capacitor-based cascaded multilevel inverter is proposed in this paper, which is constructed by a switched-capacitor frontend and H-Bridge backend. Through the conversion of series and parallel connections, the switched capacitor frontend increases the number of voltage levels. The output harmonics and the component counter can be significantly reduced by the increasing number of voltage levels. Phase opposition disposition technique is used as multicarrier modulation. The circuit topology with intended control strategy is examined for voltages, currents and THD of the system. The proposed system with POD PWM technique is implemented on MATLAB/SIMULINK model design for analysis that confirms the feasibility of proposed multilevel inverter. Keywords— cascaded multi-level inverter, multi-carrier pulse width modulation, POD, THD.
