Figure 1 Block Diagram
The PEB 4065 supports AC and DC control loops based on feeding a voltage Vab to the
line and sensing the transversal line current Iab (Figure 2).
It converts a unipolar input voltage V2W into a differential output voltage Vab with an AC
receiving gain of
Gr = VabAC/V2WAC = 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
VabDC = VBAT – VHINT + Vfix – 40 × V2WDC
VBAT negative battery voltage
VHINT internal positive supply voltage
Vfix internal voltage drop of supply filter (appr. 2 V).
Depending on the operation mode, VHINT is switched either to VH (VHINT = VH – 1 V) or to
BGND (VHINT = – 0.5 V) via the supply switch.
