5. AC Dimmer Basic Circuit
The basic circuit of AC
Dimmer is using TRIAC
to control phase angle
of sine wave

6. AC Dimmer Circuit
TRIAC, or Triode for Alternating Current (Triode
Thyristor) is an electronic component that is
approximately the equivalent of two SCRs
connected antiparallel and the gates
connected together.

TRIAC shows a toggle switch that can carry electric
current in both directions when triggered (turned on). This
can be ignited by either a positive or negative voltage at
the gate electrode. Once ignited, this component will
continue to deliver until the current flowing is lower than
the handheld current, for example at the end of the half
cycle of alternating current
