2.5 CV power supply and CC power supply
The unit is capable of both constant voltage and constant current
operation. This section describes these operations.
The ideal constant voltage power supply has zero output impedance
at all frequencies and maintains a de
fi nite constant output voltage
with respect to variations in load current. The ideal constant current
power supply has in
fi nite output impedance at all frequencies and
compensates for load resistance variation by changing the voltage to
maintain a constant output current.
However, the output impedance of an actual constant voltage or con-
stant current power supply is neither zero nor in
fi nite, and they have a
de fi nite frequency response. In addition, maximum voltage or maxi-
mum current constraints on output are a factor, leaving these power
supplies unable to maintain constant voltage or current with respect to
all changes in load current or load resistance.
Basic operations of the constant voltage (CV) and constant
current (CC) modes
The following describes the relationship between the basic operations
in constant voltage (CV) and constant current (CC) modes and limit
setting of the unit.
The following description assumes a power supply with a DC output
of 100 V and 10 A (maximum rated output voltage of 100 V, maxi-
mum rated output current of 10 A) as a model.
