This study analyzes the single and multiple IGBT switch open circuit fault in an inverter fed induction motor (IM) using Finite Element Method. The finite element simulation is carried out in ANSYS Maxwell and Simplorer for various fault conditions such as single IGBT switch open in an inverter leg, two IGBT switch open in the inverter same leg and in different leg. A three-phase 7.5kW IM is modelled in ANSYS Maxwell which is fed through a three-phase voltage source inverter modelled in ANSYS Simplorer. Inverter switches are controlled using sinusoidal pulse width modulation technique. Several electromagnetic parameters such as torque, speed, line voltage, phase current, flux line & flux density distribution over the machine and radial air gap flux density are analysed.
