Abstract: CSIs are noticeable highlights contrasted with VSI. The CSIs are a reduced amount of influenced by grid voltage changes, their control is straightforward and they have natural short circuit security. This investigation proposes a novel seven level CSI. The proposed methodology is performed with parallel association of two-switch modules. The estimation of current sources in every module, can be worked in two ways of task: symmetric and asymmetric. In this purposed topology the CHB created as far as the quantity of switches, the quantity of sources, add up to device switch power, and power misfortunes. It demonstrates an extraordinary change in execution of the projected symmetric and asymmetric Configurations are contrasted with customary structures. The projected circuit demonstrates a fascinating element which is the CE linking of the main switches. This course of action prompts straightforward gate drive circuits. The seven-level symmetric topology and fifteen-level asymmetrical topology are reenacted and the research facility models of them are materialized. The presented simulation results validate the feasibility of proposed topologies.
