Universal triac control with optocoupler p. Triac control using microcontrollers. It can conduct current in either direction between its mt1 and mt2 terminals and can thus be used to directly control ac power.
The circuit diagram for the same is shown below.
When triacs are used as light dimmers or for phase control application the gate pulse that is supplied to the gate pin has to be controlled using a microcontroller. Simple triac switch circuit. This universal triac controller circuit with optocoupler solves the problem that triacs have when functioning at low temperatures time delay switch with triac. It can conduct current in either direction between its mt1 and mt2 terminals and can thus be used to directly control ac power.
