Abstract: In order to eliminate the reverse current problem and realize the double-frequency modulation,a hybrid cascaded H-bridge（CHB）13-level inverter topology with a voltage ratio of 1∶1∶2∶2 and a hybrid phase-shift pulse width modulation（PS-PWM）method are proposed. Simultaneously,in order to solve the power balance problem of the high-voltage cells in the inverter,a power balance method based on logic operation is also presented. The simulation and experimental results show that the hybrid PS-PWM method can make the hybrid CHB inverter have 4 times frequency characteristics,can ensure the high-voltage cells tooperate at the fundamental frequency,and can also achieve the power balance of the high-voltage cells after power balance control.
