Abstract

In this paper, a new robust integral linear quadratic controller (ILQC) is proposed for Four Leg interleaved boost converters (FLIBCs) uses in the photovoltaic systems. Compared to classical boost converters (CBC), IBCs are used in the high power and voltage application. Therefore, the IBC can convert a high-current low-voltage input to a low-current high-voltage output and presents higher efficiency, lower current ripple, and better reliability. In order to enhance the photovoltaic system robust performances as reliability and efficiency of the converter, the proposed robust ILQC is calculating with the consideration of equal current sharing. Results of the proposed technical are compared with those of a classical boost converter (CBC) and FLIBC based on PI control. Performances of FLIBC based on proposed ILQC are tested in several simulations using Sim Power Systems and S-Function of MATLAB/SIMULINK. It is observed that the ILQC based FLIBC is maximizes the conversion efficiency of photovoltaic systems, improving the response time, reduce the overshoot of the waveforms, and decrease the current ripple. Compared to classical PI control, the proposed robust ILQC can increase the efficiency of conversion under different irradiance levels.
