Operating modes
Feeding and regenerative operation
Operating point -6-:
Current or voltage control.
In the area of operating point -6- the load current is reduced within
the device at low load voltages ULoad.
Dynamic consideration of the control error at the set value limit
Decision as to which control is used.
There are 3 control types in the power supply:
Voltage control
Current control
Power control
Which control is used is explained in the following sketch of the principle
of operation.

Fig. 14 Control principle – example with 2 controllers and their manipulated
value u
The decision in limit cases as to which controller defines the manipulated
value u is decided via the magnitude of the manipulated value u.
If the difference between the manipulated value u and the controlled
value y |u1-y| > |u2-y| control is via controller 2.
If the difference between the manipulated value u and the controlled
value y |u1-y|< |u2-y| control is via controller 1.
