Design and implementation of FPGA-based high power LED lighting system for ships

Abstract

Light emitting drive system used in ships induce less input side power factor with highly distorted line (AC) current which brings down the quality of AC power supply system. To suppress these limitations, futuristic ANFIS tuned PI controller operated modified SEPIC rectifier is designed and the effective analysis and results are presented in this paper. More desirable power quality is achieved with ANFIS tuned PI controller when compared with PI/fuzzy tuned PI controller in ship’s LED light module. LED driver module of 48 V, 100 W power rating is built and its upgraded operating performance is accomplished by the execution of controller in FPGA Spartan–6 platform. The satisfactory result of 2.927%-line current harmonic distortion and supply side 0.9991 power factor (within IEEE-516 standard) is attained. Steady state study involving 0.09 s, rise time with zero overshoot is acquired.
