Abstract

A novel switched-capacitor inverter is proposed. The proposed inverter outputs larger voltage than the input voltage by switched capacitors in series and in parallel. The maximum output voltage is decided by the number of the capacitors. The proposed inverter, which does not need any inductors, can be smaller than a conventional unit which consists of a boost converter and an inverter. Its output harmonics is reduced compared to the conventional single phase inverter. The proposed inverter is driven by the multicarrier PWM method. In this paper, the circuit configuration, the theoretical operation, the simulation results with MATLAB/SIMULINK and the experimental results are shown. The experimental results accorded with the theoretical calculation and the simulation results.
