If a circuit is to switch a mains voltage, a relay is a simple solution in cases where switching times are long and high currents are involved. However, at lower currents, and in particular where ...

This universal triac controller circuit with optocoupler solves the problem that triacs have when functioning at low temperatures (triac needs higher gate current) by adding a transistor at the output ...

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 ...
