Design of automatic soil humidity control using Maximum Power Point Tracking controller

Abstract

The photovoltaic system uses the photovoltaic array as a source of electrical power for the direct conversion of the sun's radiation to direct current without any environmental hazards. The main purpose of this research is to design of a converter with Maximum Power Point Tracker (MPPT) algorithm for any typical application of soil humidity control. Using this setup the major energy from the solar panel is used for the control of soil humidity. The design of the converter with MPPT together with the soil humidity control logic is presented in this paper. Experimental testing of the design controller is implemented and evaluated for performance under laboratory environment.
