We are all familiar with the snap-on phenomenon of inexpensive TRIAC dimmers that are often used to control incandescent lamps –turn the pot until the light comes (snaps) on and then reduce the ...

Diacs and triacs are often used for control of ac lines and are seeing increasing use in Internet-enabled line switches. However, the traditional approach of modeling them using bipolar transistors ...

This light dimmer control has active timing capacitor reset or AC line zero-crossing synchronization. The 13 additional components are garden variety and cost less than $2. Performance at the low end ...
