DESCRIPTION
Overview
This project is designed to give a smooth start to the induction motor based on the SCR firing triggered by heavily delayed firing angle during starting and then gradually reducing the delay till it reaches zero voltage triggering. This results in low voltage during start and then gradually to full voltage. Thus the motor starts slowly and then slowly picks up to full speed.
This project consists of a six anti-parallel SCRs, two for each phase, the output of which is connected to a set of lamps representing the coils of a 3 phase induction motor. The charging and discharging of capacitors is interfaced to comparators resulting in delayed firing pulses during start and then gradually reducing the delay till the motor runs at full speed. Output from the comparators is fed through opto-isolators to trigger the SCRs.
Further the project can be enhanced by using IGBTs in place of SCRs with PWM control to reduce harmonic distortions often encountered in SCR triggering mechanism.

I have come to know about edgefx through my senior. So, i directly google the website.. I have decided to buy project from edgefx because i have no time and i like most about edgefx kit was DIY kit (DO it Yourself) Kit the kit was delivered on time with right components.. i have searched in the website and i have purchased it..

I came to know about Edgefx through my friend and I was searched for 3 phase projects. I know about edgefx that it is reliable. Everything is fine One of my Staff helped me to how to place an order a project.

I was searched my project Electronic Soft Start for 3 Phase Induction Motor and i find edgefx in Google. I found my project Title so decided to buy that project from Edgefx. I have purchase through online
