As the voltage is built up, uncontrolled output pulses are
avoided by internal voltage monitoring. Apart from that
all the latches in the circuit (phase control, load limit
regulation) are reset and the soft-start capacitor is short
circuited. This guarantees a specified start-up behavior
each time the supply voltage is switched on or after short
interruptions of the mains supply. Soft-start is initiated
after the supply voltage has been built up. This behavior
guarantees a gentle start-up for the motor and auto-
matically ensures the optimum run-up time.
Phase Control
The function of the phase control is largely identical to the
well known IC family U211B. The phase angle of the
trigger pulse is derived by comparing the ramp voltage V
3
which is mains synchronized by the voltage detector with
the set value on the control input, Pin 4. The slope of the
ramp is determined by C and its charging current I . The
charging current can be varied using R at Pin 14. The
maximum phase angle,
α
max,
can also be adjusted by
using R (minimum current flow angle
min
) see figure 4.
When the potential on Pin 3 reaches the set point level of
Pin 4, a trigger pulse width, t
p
, is determined from the
value of C (t
p
= 9 s/nF). At the same time, a latch is set
with the output pulse, as long as the automatic
retriggering has not been activated, then no more pulses
can be generated in that half cycle. Control input at Pin 4
(with respect to Pin 10) has an active range from
V
8
to –1 V. When V
4
= V
8
, then the phase angle is at its
maximum,
α
max,
i.e., the current flow angle is minimum.
The minimum phase angle,
α
min,
is set with V
4
Automatic Retriggering
–1 V.
The current-detector circuit monitors the state of the triac
after triggering by measuring the voltage drop at the triac
gate. A current flow through the triac is recognized, when
the voltage drop exceeds a thres hold level of typ. 40 mV.
If the triac is quenched within the relevant half-wave after
triggering; for example owing to low load currents before
or after the zero crossing of current wave or; for commu-
tator motors, owing to brush lifters. Then the automatic
retriggering circuit ensures immediate retriggering, if
necessary with a high repetition rate, t
pp
/t
p
, until the triac
remains reliably triggered.
