COMPARISON BETWEEN LS-PWM AND LPS-PWM FOR SWITCHING-CAPACITOR (SC) INVERTER
Kufa Journal of Engineering, 2021 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.
