Speed regulator for universal motors
the maximum angle with the triac on (fired). This
happens when the triac is fired with minimum delay
from the zero cross. MIN corresponds to the
minimum time the triac is fired. This happens when
the triac is fired with maximum delay from the zero
cross.
If the IGN < MAX ,then IGN = MAX, thus firing with
max angle. If MAX < IGN, then firing is done with
IGN angle. The IGN value is compared with the
value of a down counter, which is clocked by DCLK
= 100kHz and is cleared at the beginning of every
half period of the AC line. When this counter value
gets equal to IGN a firing circuit produces an ignition
pulse GATE with a duration selected with option
DUTS[1:0].
After each firing pulse the ignition detector is
activated. This will check whether the triac is fired
correctly and thus no additional firing pulses are
required. If there is no current flowing in the triac
additional pulses will be generated.
