Solar Powered BLDC Fed Air Cooling System

Abstract: In the present scenario solar energy is at its booming stage. Compare to other resources, the use of solar energy creates great differences in day to day life. This paper proposes a solar-powered BLDC fed air cooling system. With the isolation of solar energy and temperature, the characteristics of the PV module may also change. For every PV system, Maximum Power Point Tracking (MPPT) should be included. The solar tracker added a modified perturb and observe (P&O) MPPT algorithm to double- check the efficiency of the system. Here in the paper a simple and efficient solar Photovoltaic (PV) air cooling system fed with BLDC motor drive. This SPV air cooling system consists of power conversion stages. In the first stage, extracts the maximum power from an SPV array by controlling the duty ratio of a DC-DC boost converter. The duty cycle of the boost converter, which maintains the output voltage of the inverter to control the Brushless DC (BLDC) motor to drive the system. A scalar controlled Voltage Source Inverter (VSI) serves the operation of the BLDC motor. The VSI is operated at the fundamental frequency, which minimizes the switching loss. The proposed air cooling is designed to obtain system performance even under dynamic conditions. The effectiveness and performance of the system are evaluated and verified using MATLAB /Simulink platform.
