Abstract
This paper presents a new front end boost switched capacitors based asymmetrical seven level DC-AC converter with single input DC source. It has potential applications for low voltage fuel cell, PV cell inverters, electric vehicles, energy devices etc. with front end multilevel output boost (MOB) switched-capacitors and uses a single input DC source for generating multilevel output voltage waveform. The proposed MOB converter generates asymmetrical DC link output voltage that is converted into AC using one H-bride inverter and auxiliary switches. Operation of the proposed topology is explained with the use of a single seven-level boost inverter and the appropriate control scheme is also presented. Simulation results using MATLAB are given to verify the proposed topology.
