Evaluation of Induction Motor Drives Efficiency using ARM-7 based VSI

Abstract

The industries that are dependent on three-phase power never sustain the single or two phase failure because three-phase power provides greater reliability than that from a single or two-phase power source in today's competitive environment. When any one of the phases in an electrical circuit fails, the equipment it powers is more likely to function improperly, and it could even stop working altogether. There is a discussion in this paper of the development of a ‘Voltage Source Inverter’ for a ‘Three Phase Induction Motor’ that includes a Three Phase Preventer. This inverter has the potential to be applied to a wide variety of industrial applications that demand a continuous three-phase power supply. The goal of this study is to figure out how to build a system that uses a 3 ph. power source to supplement a single-phase one. An Arm-7 controller is programmed for gate pulse of pulse generator, which will allow the desired result to be attained. There is optoisolator and gate driver circuitry attached to this controller, and a MOSFET is used to link it to a power inverter. The foremost goal of this study is to implement a 3 ph. 6 trigger, isolated pulse using an ARM-7 controller. When one of the phases is missing from a three-phase supply in the RYB sequence, this ‘automatic phase selection circuit’ chooses the current phase to consider as a single phase with neutral, protecting a 3 Ph. preventer fortified induction motor from single-phasing damage. The induction motor is powered by 350 volts of three-phase alternating current (AC) that is generated by an inverter circuit. The power circuit transforms 230 V of 1 Ph. AC to DC 350 V. In order to deliver the three-phase variable frequency supply that is essential for adjusting the speed of induction motors in a diversity of manufacturing applications, the circuit has been built.
