Designing high gain DC DC converter Model for bldc drive application Using sustainable energy system

Abstract

Renewable energy sources are widely utilised in several applications, which need control algorithm for maximum power extraction, enhanced dynamic performance and efficiency. In this work, solar energy is one of the input source in which Fuzzy Logic Controller (FLC) acts as a Maximum Power Point Tracking (MPPT) technique to detect peak power from a PV array, improving the efficiency of solar-powered drives under variable weather conditions. High sensitivity during fluctuations, convenience of programming and changes in the atmospheric condition are the features of FLC controller. Under poor solar irradiances use a another energy source as wind farm in which a PI controller is used to sustain the required potential to drive the BLDC motor. Due to insufficient output voltage from solar array forces to develop voltage lift converter with high voltage transfer gain dc-dc to operate in continuous condition mode in order to use high power application. To assure the converter stability and the controller robustness, a state space model is developed using a reduced order model for the high gain Luo converter in continuous time domain. Between the solar array and VSI (Voltage source inverter), a power converter configuration is introduced which works as an intermediate section of MPPT based solar module. newlineBased on converter performance, efficiency, cost, design and simplicity, the control topology of FLC based MPPT technique is analyzed and executed. newline
