A novel PWM switching method for seven-level switched-capacitor inverter using series/parallel conversion

this paper proposes a new method for pulse width modulation (PWM) for seven-level switch-capacitor inverter using series/parallel conversion (SCISPC). This multilevel inverter can generate 7 level voltages in output with using just one voltage source while using minimum switches. This paper present the new method applied in SCISPC and then compare with Level and Phase shifted PWM (LPS-PWM). This method has been simulated in Matlab/Simulinks and the result shows high reduction in Total Harmonic Distortion (THD) while capacitor ripple is the same.
