Abstract
Proposed topology consists of a new switched-capacitor dcdc converter (SCC) which has boost ability and can charge capacitors as self-balancing by using proposed binary asymmetrical algorithm and series-parallel conversion of power supply. Proposed SCC unit is used in new configuration as a sub-multilevel inverter (SMLI) and then, these proposed SMLIs are cascaded together and create a new cascaded multilevel inverter topology which is able to increase the number of output voltage levels remarkably without using any full H-bridge cell and also can pass the reverse current for inductive loads. Switched-capacitor multilevel inverters (SCMLIs) which can generate a great number of voltage levels with optimum number of components for both symmetric and asymmetric value of dc voltage sources. In this case, two half bridges modules besides two additional switches are employed in each of SMLI units instead of using a full H-bridge cell which contribute to reduce the number of involved components in the current path, value of blocked voltage, the variety of isolated dc voltage sources and as a result the overall cost by less number of switches in comparison with other presented topologies. The validity of the proposed SCMLI has been carried out by several simulation and experimental results.
