This potential problem can be remedied by extending the triac pulse as
the phase angle approaches 180
°
. Extending the triac pulse out to about
135
°
will accommodate inductive loads with a current phase angle up to
45
°.
This is suitable for most applications.
Extending the triac pulse is illustrated in
Figure 1-10
.
Figure 1-10. Triac Pulse at Different Phase Angles
Zero degrees and 180
°
also require special attention. At zero speed, the
desired output is zero voltage and the triac should not be fired. Firing the
triac at zero degrees would give full speed operation. If the desired
phase angle is too small, the triac should also not be fired. If the triac
pulse were to overlap the next voltage zero crossing, the voltage would
jump from 0 to 100 percent, resulting in an undesirable plugging of the
motor.
