Heat measurement at various parts of three phase induction motor at low speed using Z-source filter

The stator temperature of the three phase induction motor with Z-source inverter drive is experimentally studied in this paper along with the comparison of the stator temperature of three phase induction motor with PWM 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.
