A hardware implementation of LUO converter fed BLDC motor drive for power quality improvement

Abstract

The extensive coverage of solar PV systems have revolutionized the application of power electronics concept in agricultural field. In present scenario, solar based pumping electric motor are being used in more common for ground water based irrigation purpose. Since the output of solar system is DC and highly variant, we require an inverter and suitable controller to do the required supply conversions and maximum power tracking respectively. In conventional systems, a diode or thyristor based inverter fed induction motors are used which is the reason for low power factor at supply mains and low efficiency at load side. In order to overcome this issue, the idea proposed is to employ a BLDC motor fed by LUO converter and two level inverter. Owing to the nature of performance enhancement of LUO converter and BLDC motor, this arrangement provide improved power quality at supply mains, reduced torque ripple end high efficiency.
