Output Characteristic Curves of Power Supply
Units
A sound circuit concept is often revealed when it is first started. The output characteristic
curve used is typical of the power supply unit behavior. The characteristic curve specifies
the history of the output voltage as a function of the output current. It must be noted that
capacitive loads (e.g., DC/DC converter or PTC thermistor) consume a much higher
current during start up than during nominal operation.
Capacitive loads represent an overload or a short circuit for the power supply unit for a
short time. It is therefore of great importance to the design of an operational system that
the power supply unit does not interpret this transient overload or short circuit as an error
and does not shut down. It greatly depends on the output characteristic curve to determine
which loads can be safely started with which power supply unit.
For this reason, the different characteristic curves are explained in more detail in the
following.
When using the fold-back characteristic, power supply units switch off shortly in the
event of a short circuit or an overload and restart the load after a short time.
Power supply units with U/I characteristic continue to provide the complete output
current while reducing the output voltage.
Power supply units with U/I characteristic and power boost have the advantages of a
U/I characteristic combined with an additional power reserve. The power reserve
ensures a constant output voltage even in the event of an overload.
