摘要：

A fuzzy logic controller has been developed for interfacing PV array with utility grid through a three-phase line-commutated inverter for the first time. The controller tracks and feeds maximum power to the utility grid. The linguistic variables have been selected appropriately to modulate the. ring angle of the inverter for tracking the maximum power. The simulink model of the proposed scheme employing fuzzy logic controller has been built using MATLAB/PSB. A PIC microcontroller has been programmed for generation of. ring pulses to the thyristors in the inverter. Experimental setup of the proposed scheme has been built and the results obtained on a PV array of 54 V, 12 A rating are presented. The comparison of experimental and simulation results shows very close agreement between the two thus validating the controller proposed. (C) 2008 Elsevier Ltd. All rights reserved.
