Diacs and triacs often are used for line-voltage control. They also are getting additional interest as part of Internet- and cell-phone-controlled power-line switches such as the Belkin WeMo Home ...
Triacs are at the heart of dimming controls for LED lighting. Triacs used in dimmers have normally been characterised and specified for incandescent lamp loads, which have high current ratings for ...
Pre-regulators at the input of power supplies minimize losses. This version uses optical feedback from an LED and light-dependent resistor instead of the more common optically isolated TRIACs. Fig 1.
