Abstract

An AC motor draws high initial starting current that is many times greater than the rated current of the motor by using contactor/relay-based starter.This condition is not favourable in power distribution system since it can lead to power sags for a short period,and also may cause protection device to trip.Sudden start and stop of AC motor also can cause harsh vibration thus lead to mechanical stress of motor base structure.To overcome these problem,a soft starter device will be designed and developed based on microcontroller-based AC phase angle control.The simulation work of this project is performed by using Proteus 7 software.The prototype is developed by using Arduino Uno as main controller interfaced with Liquid Crystal Display (LCD) display and zero-cross detector as input signal.Triode for alternating current (TRIAC) – based circuit to control AC conductivity phase angle is used to drive single phase AC motor.In the end of the project,the developed prototype is successfully able to provide soft start operation of AC motor which can minimize vibration and the occurrence of power sags. Subsequently,the maintenance cost can be reduced and the life span of an AC motor is expected to be much longer.
