Abstract
The uses of induction motor is ever-growing day by
day because of its superiority and high efficiency over dc
machine. So for wide range of use in the industry, this machine
requires an efficient driver circuitry arrangement. Currently
conventional Voltage Source Inverter (VSI) or Current Source
Inverter (CSI) is dealing as key part in the field of induction
motor driver circuit. These converters fail to perform at our
desire level due to some crucial drawbacks like they can perform
as either buck or boost operation and they contain considerable
amount of harmonics as well as EMI noise. So we are trying to
replace these traditional inverters by PWM control Z-Source
Inverter (ZSI) which offers buck-boost operation capability by
utilizing shoot through state and provides less EMI noise. This
paper presents a comparative study among these three inverters.
Firstly three MATLAB simulation model of Induction motor
driver by using VSI, CSI and ZSI (having almost same
environment) have arranged. Then some important motor
characteristics such as rotor speed, electromagnetic torque, rotor
current and stator current have observed for three system
models at various loading conditions. The model using Z-source
inverter exhibits efficient performance in all cases compared to
the other models.
