A Sliding Mode Controller Based Boost Converter for Grid Connected Solar PV System

In this paper, the grid connected PV system is proposed and the control technique of solar system with three phase grid connection is done by sliding mode controller. The aim of this paper is to design the system that improve source side power and control harmonics at the grid side current. The converter has interfaced between the generated PV arrays to three phase RL load with three phase grid. This system consists of voltage source inverter, boost converter, PV array, and nonlinear load. The proposed sliding mode control method is making the system in stable, and which performs the system robust quite. The converter is connected to the input side voltage source inverter to step up the generated PV array voltage. Three phase inverter is using sliding mode control to provide switching signals, and control the transferred active power to grid system and load. The proposed system model is developed using in MATLAB/Simulink.
