A High Performance DC-DC Converter with Battery Charging Circuit

چکیده
This paper introduces a bi-directional DC-DC converter with adaptive fuzzy logic controller (AFLC). Bi-directional power flow is obtained by the same power components and provides a simple, efficient, and galvanically isolated converter. In the presence of DC mains, the converter operates as buck converter, powers the down stream converter, and also charges the battery. When the DC mains fails, the converter operates as a boost converter and the down stream converter is fed by the battery. In both modes the power switches are controlled by the Pulse Width Modulation (PWM) technique and the pulses are generated by the application of fuzzy logic with an adoption algorithm. The proposed converter is simulated using MATLAB® and a laboratory prototype is developed to validate the simulation results. (
