Asymmetrical cascaded sub cell multilevel inverter is proposed here in order to overcome the disadvantages faced in the symmetrical cascaded multilevel inverter. Asymmetrically cascaded sub cell model is generated by grouping up basic unit cells in series connections in each phase of the model. DC supply voltages of basic unit sub cells in each phase will have an arithmetic sequence with common difference of E. Low frequency and high frequency pulse width modulation techniques (PWM) can be used efficiently and easily for different operating conditions. This proposed structure reduces the number of switching devices, no. of driver circuits, reduces installing space for the proposed model, cost and voltage across the switches. © Research India Publications.
