TCA 785
Functional Description
The synchronization signal is obtained via a high-ohmic resistance from the line voltage
(voltage
V
5
). A zero voltage detector evaluates the zero passages and transfers them to the
synchronization register.
This synchronization register controls a ramp generator, the capacitor
C
10
of which is charged
by a constant current (determined by
R
9
). If the ramp voltage
V
10
exceeds the control voltage
V
11
(triggering angle
), a signal is processed to the logic. Dependent on the magnitude of the
control voltage
V
11
, the triggering angle
can be shifted within a phase angle of 0 to 180.
For every half wave, a positive pulse of approx. 30
μ
s duration appears at the outputs Q 1 and
Q 2. The pulse duration can be prolonged up to 180 via a capacitor
C
12
. If pin 12 is connected
to ground, pulses with a duration between
and 180 will result.
Outputs
and
supply the inverse signals of Q 1 and Q 2.
A signal of
+180 which can be used for controlling an external logic,is available at pin 3.
A signal whichcorresponds to theNOR linkof Q 1 and Q 2 is available at output Q Z(pin 7).
The inhibit input can be used to disable outputs Q1, Q2 and
Pin 13 can be used to extend the outputs
and
Q 1
,
.
to full pulse length (180 –
).
