Abstract

Nowadays for energy generation solar PV based system has came up as an important alternative. A solar PV fed water pumping system using an induction motor drive has been discussed in this paper. Solar PV array, modified SEPIC DC-DC Converter, a three phase voltage source inverter and a motor pump assembly are the main parts of the water pumping system. In a solar array fed water pumping system there are two stages. The first stage is to control the duty ratio of the dc-dc modified SEPIC converter to extract the maximum power from the Solar PV array. Under varying irradiance and temperature conditions, INC control method is utilized for maximum power point tracking (MPPT) of PV systems to control the duty ratio. In the second stage, switching pulses of the VSI is controlled by v/f controller based on the sinusoidal pulse width modulation. The frequency of SPWM is controlled for controlling the stator frequency of the IM.
