Abstract: This paper describes the design and implementation of three-phase inverter. Generally inverters are used in high power applications as industrial based induction motor etc. Here the Three-phase Inverter is formed by three legs, each leg consists of two switches. So there are total of six switches. This Three-phase Inverter circuit consists of MOSFETs/IGBT’s as switching devices for which the gate pulses are given using Microcontroller. The microcontroller used here is ARDUINO/NI-MYRio through which pulses are generated and given to the switches. The operation of Three-phase Inverter can be performed in two different conduction mode, which are 1800 and 1200mode. In this thesis the operation is performed through 1800 conduction mode. Arduino is interfaced with Mat Lab, where the pulses are generated in the mat lab and given through Arduino. In case of NImyRIO, pulses are generated through LabVIEW software.In this paper the hardware implementation of this three phase inverter which is fed to a three phase induction motor is successfully carried out.
