Abstract: This document is used to explain about an efficient controlling method of multi level inverter with a Z-source network. The proposed method is an efficient control design for the optimisation difficulty which contains maximising or minimising of a real operation by methodically deciding input values from within a permissible group and calculating the value of the operation. The reduction of error between the real load voltage and its reference value is optimising the gain parameters in the projected control methodology. It contains better capability to reply quick alterations in different operating situations. The projected method is used to decrease the inrush current, harmonics, increase effectiveness and it develops the exchange effectiveness for broad range of loading situation. It also improves the guideline of the output voltage and capacitor voltage stress. The projected technique is executed in MATLAB/Simulink platform and the efficiency is compared with the predictable methods.

Keywords: GSA algorithm; THD minimisation; switching angle; multilevel NPC Z-source inverter.
