Control strategy for modified CI-based Bi-directional Γ-Z source DC-DC converter for buck-boost operation

This paper introduces a novel Bi-directional coupled-inductor (CI) based Γ-Z source converter for step up-step down DC application. It is modified version of CI high gain converter. The originates under the family impedance networks with two winding coupled inductor. said when operated low duty ratio makes to achieve compared conventional DC-DC converters. As society in trend electric vehicles (EV’s) are recommending operating converters mode have continuous power flow those green technologies. So, same initially and verified as buck boost open loop mode. Nearly 38 4 voltage-gainin was observed realized MATLAB environment designed inductor capacitor values 49% 1% cycle respectively open-loop configuration. In succeeding PID controller closed control strategy has implemented Gain sensitivity had been Simulink environment. Results obtained from simulation mathematical found satisfactory loop.
