Design of P-V Based Pumping System

Abstract : This paper presents design and analysis of a single phase induction motor drive using IGBTs at the inverter power stage with volts hertz control (V/f) in closed loop using ATMEGA32 as a controller.The power converter & the microcontroller unit (MCU) acts as an interface between the solar panel & the SPIM. The power converter is a H-bridge converter composed of four IGBT and for switching ON/OFF these IGBT’s requires a driver circuit which are operated according to the SPWM technique controlled by the MCU. Mathematical analysis is carried out to demonstrate the feasibility of the proposed approach. Microcontroller (ATMEGA32) is used to generate the SPWM pulses for inverter to drive the 0.5 Hp, 1-phase Induction Motor.Detailed investigation of the project has been discussed below.
