Triacs are bidirectional ac switches that can control loads with currents as high as 25A rms at voltages as high as 600V. They find wide use in motor-speed, heater, and incandescent-lamp controls.
Several different technologies and designs are available among solid-state switches today. The major families are the standard Triacs (triode for alternating current), the snubberless Triacs, and the ...
To understand the technology associated with practical LED dimming we first have to look at the technology associated with triac-based incandescent lamp dimmers. The typical triac lamp dimmer circuit ...
