Abstract :
Most Maximum Power Point Tracking (MPPT) techniques for Photovoltaic (PV) systems require one or more of the following sensors: voltage sensor, current sensor, temperature sensor, solar irradiance sensor. This paper introduces a new MPPT control algorithm called Input Characteristic Impedance (ICI) method which uses just a single voltage sensor. The method is based on the maximum power transfer theorem, where the Input Characteristic Impedance of the DC-DC converter is modified to reach the Maximum Power Point (MPP). This technique can be applied to any DC-DC converter like Buck, Boost, Buck-Boost, Cúk, SEPIC and Zeta, and to validate the new proposal the last was chosen.
