UAA145
Phase Control Circuit for Industrial Applications
Description
The UAA145 is a bipolar integrated circuit, designed to
provide phase control for industrial applications. It
permits the number of components in thyristor drive
circuits to be drastically reduced. The versatility of the
device is further enhanced by the provision of a large
number of pins giving access to internal circuit points.

Pulse Phasing Limits
The pulse phasing front limit is determined by limiting
the maximum shift voltage applied to Pin 8 which is thus
adjustable by external circuitry. This can be done by
connecting a Z-diode between Pin 8 and Pin 3. The pulse
phasing rear limit, öh, is the residual phase angle of the
output pulses when the shift voltage Vö is zero. Since
öh coincides with the zero crossover point of the ramp, it
can be adjusted by variation of the time constant CsRs
(figure 14). Figure 10 shows the pulse phasing rear limit
plotted as a function of Rs.
Pulse Blocking
The output pulses can be blocked via Pin 6, the memory
content being erased whenever Pin 6 is connected to +VS
(Pin 1). This effectively de-activates the pulse generator;
any output pulse in the process of generation is inter-
rupted.
Pulse blocking can be accomplished either via relay
contacts or a PNP switching transistor (figure 14).

Output Pulse Width
The output pulse width can be varied by adjustment of Rt
and Ct. In figure 11 pulse width is shown plotted as a func-
tion of Rt for Ct = 50 nF.
The output pulse always finishes at zero crossover. This
means that if there is a minimum pulse width requirement
(for example, when the load is inductive) provision must
be made for a corresponding pulse phasing rear limit. The
output stages are arranged so that the transistors are cut
off when a pulse is produced. Consequently, the thyristor
trigger pulse current flows via the external load resistors,
this current being passed by the transistors during the
period when no output pulse is produced. During this
period the output voltage drops to the transistor saturation
level and is therefore load dependent. Figure 12 shows
the relationship between saturation voltage and load
current.
Shift Characteristic
In figure 13 the angle of phase shift is shown plotted as a
function of the voltage applied to Pin 8 for a pulse phasing
rear limit of approximately 0_. Because the ramp wave-
form is a part of the exponential function, the shift curve
is also exponential.
The limitation of the shift voltage to approximately 8.5 V
is due to the internal Z-diode Z4, which has a voltage
spread of 7 to 9 V.
The waveforms in figures 7 to 9 show the output pulse
phase shift as a function of Vö. It can be seen from the
oscillograms, the instants at which pulses are released
coincide with the intersections of the ramp and the shift
voltage.
