Abstract
Buck Boost Converter with Coupled Inductor (BBCCI) can be to used match the DC input source voltage with the load voltage. The modeling and control of BBCCI becomes an important issue. This work deals with modeling and simulation of BBCCI system with proportional resonant (PR) controller. The objective of this work is to improve dynamic response of closed loop BBCCI system using PR controller. The closed loop controlled BBCCI systems with PI and PR controllers are modeled, simulated and the results are analyzed. The results indicate that the dynamic response is improved using PR controller. The proposed system has advantages like reduced THD, low settling time and steady state error. The hardware for BBCCI is tested and experimental results are compared with the simulation results.
