RE: Dimmers



Original poster: biomed-at-miseri.winnipeg.mb.ca 


"Phase control" is the right term to be used on lamp dimmers.  It is used
in power electronics equipment too.  The word phase is used because : as
you adjust the lamp dimmer's potentiometer, you are adjusting the time
delay after zero crossing that the triac is triggered, hence they call it
phase control.
