Impedance source Inverter for Water Pumping Application

Abstract

Impedance source inverter for driving Dynamic model of Induction Motor rated at 3HP for water pumping application is presented in this paper. ZSI can operate in the shoot through condition, unlike typical voltage and current source inverters. The usual PWM technique is changed to either increase or decrease the voltage level available at the inverter's input using the simple boost control mode. Additionally, this system only requires one stage of power conversion, negating the requirement for a second DC-DC converter. Using MATLAB Simulink, the system is validated for the intended parameters.
