Abstract:

DC-DC converters can be viewed as dc transformers that deliver a DC-DC voltage or current at a different level than the input source. The unregulated DC voltage is converted into regulated DC voltage at required level under varying load and input voltage condition. The control of output voltage is performed in a closed loop using the principle of negative feedback.The fuzzy logic controller for DC-DC converters i.e. Fly-Back Converter offers an alternative way to implement a central action that exploits the inherent variable structure nature of converter. The controller acts fast to changes in the converter output voltage producing good load regulation. This control technique offers converter stability for robustness, good dynamic response and implementation is simple. Hence, this paper is the result of an attempt to design aDC-DC Fly-Back Converter and an FLC for the same. The paper also draws a comparison between a conventional PI and fuzzy controllers for the aforementioned converter.
