Abstract: This paper presents an asymmetry hybrid cascaded multilevel inverter. Firstly, the topology of the proposed inverter is introduced theoretically. Then, taking seven-level output for example, using the phase opposition disposition pulse width modulation (PODPWM) combining with feedback control method, the capacitor voltage is controlled at the desired value by adjusting the switching logic, so as to achieve the purpose of making the output seven-level. Finally, the inverter and control circuit is built in MATLAB, and the simulation results support the proposed inverter and the control method.

Key words: hybrid power supply, asymmetry multilevel, inverter, phase opposition disposition pulse width modulation (PODPWM)
