The above waveform attached shows input sinewave which is stepped down using transformer and I am using voltage based zero cross detection for firing Triac. Above waveform shows TRIAC is fired at almost 10% of Positive and Negative Half cycle. I want to remove that extra energy which getting generated because of Inductive load.I have tried changing resistor and capacitor for my snubber circuit but that didn't help.The main issue is as I try to conduct more part of sine wave like 50% of positive and negative Half the more is the inductive energy.
In above waveform I am firing Triac at 50% of both half cycles but the other half is energy coming from Inductive load. At 50% itself the voltage across inductive load is showing around 220 volts because of this extra energy.If I go even more like more than 50% the waveform gets distorted.In my case this inductive load is a Electromagentic Feeder Coil it's used for Vibratory Feeder Controller.How do I remove this energy?My requirement is of 5 Amperes.My pulse width for triac is 50uSec.
