FLC Based Performance Analysis of High- Voltage Gain DC-DC Converter for Induction Motor Drive

Electrical & Electronics Engineering

New High-Step-Up DC-DC Converter has been used and powered by solar-PV system for induction motor drive application. The provided topology includes a boost converter using coupled inductors to increase the voltage gain. This converter uses hybrid switched inductor technique to enhance its overall voltage gain. The inductors of the gain extension network are all charged together in parallel and get discharged simultaneously in series to obtain the high voltage gain (>10). Resultantly, the voltage stress experienced by the switches of the proposed converter is reduced to 55% of the desired output voltage. The main characterization of Fuzzy-Logic Control (FLC) scheme is constituted by emblematic path along with knowledge proficiency for prediction of optimal switching states to proposed high-step up DC-DC converter. The main intension of the FL controller is used to regulate the sudden disturbances coming from the load and getting enhanced performance over the formal PI controller. The main objective of this work is proposing a novel dual switch high step-up DC- DC converter fed VSI based induction motor (I.M) drive is controlled and powered by solar PV system with intelligent control schemes. The well-recognition of proposed scheme is validated under constant and variable DC-link voltage conditions by using intelligent Fuzzy-logic controller which is demonstrated through Matlab/Simulink tool and results are conferred with proper comparisons.
