ADDING
THE
POWER
SUPPLIES IN
SERIES
TO PRODUCE
HIGHER
VOLTAGE
RANGES
(Cont'd)
(a)
Bi-Polar
Power
Supply to the
common
terminal.
The
total
voltage range available
at
the+1— ^-ISV
terminal
is
-14V
to
+30V.
The
total
voltage range available
at the
-1—
-ISV
terminal
is
+14V
to
-30V.
(b)
Bi-Polar
Power Supply
to
the
+1— ^-ISV
terminal.
The
total
voltage
range
available
at
the -
1—
-15V
terminal
is
+13V
to
-45V.
The
total
voltage
range available
at
the
common
terminal
is
+NV
to
-30V.
(c)
Bi-Polar
Power Supply
to
the-l-^-15V
terminal.
The
total
voltage range available
at the
+l-*-+15V
terminal
is
H3V
to
+45V.
The
total
voltage range available at the
common
terminal
is
-14V

SUPERIMPOSITION
OF
A.C.
SIGNALS
ON
A
D.C.
POWER
SOURCE:
Using the connections given
in
Section
5-9
but switching the Bi-Polar Power
Supply
to
Power
Amplifier
and
driving the input of the Power Amplifier with the
Function
Generator
provides
a wide range of
A.C.
signals
which can be
superimposed
on
the
D.C. power
supplies.
The
A.C.
signals
can be
used
to
simulate ripple signals or switching pulses
on
power
lines.
MISCELLANEOUS
WAVEFORMS USING SYMMETRY CONTROL;
By
using the
symmetry
control
the Sine,
Square and
Triangular
waveforms can be
changed
into
the following:-
