Abstract

Switched-capacitors-based multilevel inverters are of two types: single-stage and two-stage. Two-stage topologies require four polarity-reversing switches of high blocking voltage. A single-stage topology is proposed in this work which can synthesize thirteen levels with a single input source and three capacitors, with an overall voltage gain of three. The proposed inverter uses fourteen power switches, of which the blocking voltage of ten switches is restricted to the source voltage. The remaining four switches have blocking voltage equal to twice the source voltage and they operate at low frequency. Thus, for all switches, the blocking voltage is less than the peak output voltage. The proposed module is validated experimentally and the results are presented in this paper. A comparison of the proposed topology with other similar topologies is also presented.
