The design, implementation and control of a buck boost converter based on the ZETA converter are described. The converter has a higher DC voltage gain than the conventional ZETA converter. The semiconductor switch experiences lower voltage stress. The regulation of the converter using various controller is investigated. The controllers are sliding mode, modified sliding mode, output feedback, and adaptive current mode controller. Experimental results are presented to demonstrate the performance of the converter under various operating conditions, including changes in reference voltage, load resistance, and input voltage.
