A MPPT algorithm based on the binary-search technique with ripples from a converter

This paper presents a new Maximum Power Point Tracking (MPPT) method of a Photovoltaic (PV) array based on the Binary-Search Technique and the Ripple Correlation Control (RCC) using the DC voltage and power ripples caused by a converter. The Binary-Search technique makes the operating point to converge to the MPP in a short time with simple calculation process. The proposal to combine the Binary-Search and RCC techniques enables the convergence to the MPP more accurately and quickly. The theoretical analysis and design principle of the proposed method are described in detail. Demonstrated by simulations on MATLAB/Simulink and experimental studies are presented. In addition, by comparing total output energy for the conventional Perturb and Observation (P&O) method under the same conditions, the effectiveness of the proposed method are shown.
