Minimum LED Off Time in Phase Control
Applications
In Phase control applications one intends to be able to
control each AC sine half wave from 0° to 180°. Turn on
at 0° means full power and turn on at 180° means zero
power. This is not quite possible in reality because triac
driver and triac have a fixed turn on time when activated
at zero degrees. At a phase control angle close to 180°
the driver’s turn on pulse at the trailing edge of the AC
sine wave must be limited to end 200 μs before AC zero
cross as shown in Figure 7. This assures that the triac
driver has time to switch off. Shorter times may cause
loss of control at the following half cycle.
I FT versus dv/dt
triggering of the device in the event of fast raising line
voltage transients. Inductive loads generate a commutat-
ing dv/dt that may activate the triac drivers noise sup-
pression circuits. This prevents the device from turning
on at its specified trigger current. It will in this case go
into the mode of “half waving” of the load. Half waving of
the load may destroy the power triac and the load.
Figure 10 shows the dependency of the triac drivers I FT
versus the reapplied voltage rise with a Vp of 400V. This
dv/dt condition simulates a worst case commutating
dv/dt amplitude.
It can be seen that the I FT does not change until a
commutating dv/dt reaches 1000V/μs. The data sheet
specified I FT is therefore applicable for all practical
inductive loads and load factors.
Triac drivers with good noise immunity (dv/dt static) have
internal noise rejection circuits which prevent false
