A two modulation methods of the switching-capacitor inverter are proposed. The inverter output voltage is larger than the input voltage by connect switching-capacitor in series and in parallel respectively. The level output voltages are decided by number of the capacitor. Five capacitors are used to obtain eleven level in output voltage waveform. The proposed inverter is driven by the LS-PWM and LPS-PWM methods. The circuit configuration, states operation and simulation results by using MATLAB/SIMULINK are presented in this paper. The simulation results demonstrated best LPS-PWM method compared with LS-PWM in terms THD of output voltage.
