11.3.3.2 Ripple control receiver with PCU, analogue input
The following example shows the connection of a ripple control receiver to
the analogue power input of the PCU. The ripple control receiver and the
PCU are in the same potential in the example. The assignment of the bridges
block III can be found in the table (see section 11.1.1 Description of the
elements). There is a mass connection between ripple control receiver and
PCU.

As most ripple control receivers do not have analogue feedback inputs, the
analogue PCU signal output (feedback output in the figure: item 4) does not
lead to the ripple control receiver, but is designed separately. The feedback
signal from the PCU must be further processed in accordance with the plant
concept.
