Analysis on Photovoltaic Assisted Three Phase five level Unipolar PWM Inverter for Induction Motor Driven Water Pumping System
نویسندگان
چکیده
This paper presents the analysis of a photovoltaic bases three-phase five level voltage source inverter (VSI) supplying induction motor driven water pump. The VSI uses a unipolar PWM technique for producing three phase 5 level voltage output and this output is used to drive three-phase induction motor driving a pump load. Multilevel inverters are used for generating AC voltage from several levels of DC voltages and enhance the performance of the system. The proposed system is used to reduce the filtering requirements and reduce the amplitude of all harmonics at the output of the inverter. The Power quality improves by reducing the harmonics level. The complete simulation model is simulated in MATLAB/SIMULINK and validates the theoretical considerations.

Space Vector Pulse Width Modulation with Reduced Common Mode Voltage and Current Losses for Six-Phase Induction Motor Drive with Three-Level Inverter
Common-mode voltage (CMV) generated by the inverter causes motor bearing failures in multiphase drives.On the other hand, presence of undesired z-component currents in six-phase induction machine (SPIM) leads to extra current losses and have to be considered in pulse width modulation (PWM) techniques. In this paper, it is shown that the presence of z-component currents and CMV in six phase driv...
