Constancy Investigation Of Fuzzy Controller Over Proportional Integral Controller For Resonant Converter

Abstract

In this article mainly aimed to reduce the disturbance raised in the line or load side of resonant converter. We have to achieve effective output from the resonant converter among any disturbance condition. So that the previous literature survey the resonant converter is subjected to line and load side disturbances. In the survey told that the resonant converter works along with the help of controllers will give the better output when compared with the resonant converter working alone. Here the designed resonant converter is manually subjected to line and load disturbances with input voltage of 55V supplying for 80ohms load which the converter is integrating with Proportional Integral (PI) and Fuzzy logic controller. The designed converter’s disturbance output voltages and currents waveforms of PI and Fuzzy controllers are compared by time domain specifications like peak time, raise time, settling time and peak overshoot are measured by using output waveforms and then we have to conclude that the recital working of Fuzzy controller is more effective than the Proportional Integral (PI) controller.
