An Improved PWM Integrated Solar Mini Pump Controller with Perturb and Observe-Based MPPT Topology to Extract Maximum Energy from PV Array throughout the Day

Abstract

This paper is presented with the intention of designing and developing an automated DC motor with speed control by using a Maximum Power Point Tracking (MPPT) algorithm to collect the maximum solar energy for running the motor with a Pulse Width Modulation (PWM) charge controller. The stimulated project utilizes solar energy using a PV module, boost (DC-DC) converter, LED battery and PIC microcontroller and water pump. The implementation of the proposed model can play an effective role in reducing the cost of energy consumption in Bangladesh. Traditionally used diesel pumps and electricity-powered pumps result in the estimated cost of $900 million per year for 1 million tons of diesel. Initiating the use of solar-based motors and pumps will reduce the cost by half of the current cost while also reducing the pollution and carbon footprint of using renewable power sources. The improved alternative proposed by this paper has smart controls which enable speed and current control based on solar energy by using MPPT. After completing the simulation by using Proteus software, a prototype of the proposed motor is built, and its performance is evaluated.
