Hysteretic controlled cascaded buck boost converter fed seven level inverter system

Cascaded back boost converter with seven level inverter (CBBCSLI) is a good choice between DC source and induction motor. This paper deals with comparison of closed loop controlled CBBSLI with and without hysteretic controllers. The aim of the present work is to maintain regulated voltage across the load. Simulink model developed for PI & HC based closed loop CBBSLI system and they are used for simulation studies. Matlab results show reduced current ripple by using HC. The hardware is engineered, tested and the results are compared with simulation results. The objective of this work is to improve the dynamic response of CBBCSLI using hysteretic controller.
