Dear All My Friends
I design a digital dimmer to control a vibrator ... it works but i found that around the phase angle 90 ( small angle before and small angle after) the power from dimmer is big different .... so i look at this and found that the power with phase angle control is not linear .... like s shape for the phase control delay from 0 to 180 degree .... the question is :
How can i get the lockup table to make this relation to be seem as linear
By another mean ... how can i get a time delay (or Phase angle) as a function of power as i can put a power table like (0%,10%,20%,30% .... 100%) and get the time delay for this values
Best Regards
