In this study small signal analyses of a buck boost converter for a renewable energy applications is performed and hardware implementation is realized. State equations are solved for different study conditions and transfer function of uncontrolled system is obtained for stability analyses. Experimental hardware of buck boost converter realized with a MOSFET driver circuit which is designed for high frequency, high voltage and high current implementations. Experimental studies and results are given in the paper. The results show that hardware implementation of the system is accomplished.
