Study of Stator Winding Temperature with Z-source Inverter Fed Induction Motor at low speed using V/F control

摘要

This paper presents the experimental study of stator temperature of three phase induction motor with PWM drive and compared the stator temperature of the induction motor with Z-source inverter drive. Z-source inverter employs an unique impedance network coupled with inverter circuit and rectifier. The inverter system using IGBT's, provide ride-through capability during voltage sags, reduces the line harmonics, improves power factor, increases reliability, reduces electromagnetic interference noise and low common mode noise. The line harmonic simply dissipate as heat in the stator windings, this has been minimized using Z-source filter.
