Design and Development of a Three Phase Induction Motor Drive using NI-myRIO

This paper aims to describe the design, implementation, and operation of a three-phase inverter. As a general rule, inverters are used in applications that require high power, such as industrial induction motors. This Three-phase Inverter is composed of three legs, each of which consists of two switches. As a result, there are six switches in total. Three-phase inverter circuit uses MOSFETs and IGBTs as switching devices for which a microcontroller provides gate pulses. Here, pulses are generated and given to switches employing the NI-MYRio processor. Inverters in three phases can be operated in any of two conduction modes, 180° or 120°. The operation is carried out in 180° conduction mode in this paper. It is interfaced with Mat Lab, which generates the pulses and sends them to Arduino. In the case of NI-myRIO, pulses are generated through LabVIEW software. This paper successfully implements a three-phase inverter on hardware to drive a three-phase induction motor.
