Functional Description

Block Diagram
The PEB 4065 supports AC and DC control loops based on feeding a voltage
V
ab
to the
line and sensing the transversal line current
I
ab
(
Figure 2
).
It converts a unipolar input voltage
V
2W
into a differential output voltage
V
ab
with an AC
receiving gain of
Gr
=
V
abAC
/
V
2WAC
= 40.
This is accomplished by converting the input voltage to a current which is used to
transpose the low voltage signals of the interface to the high voltage line feeding section.
This current is reconverted to two voltages of opposite phase which are referenced to
the positive and negative supply voltage, respectively. Thus the differential DC
line-voltage in all normal polarity modes except ringing is related to the input voltage by
