following figure. The CR mode ensures that the UUT voltage outputs remain
stable when the load varies.
5.1.3 Complex Operation Mode
Complex operating modes include CV+CC, CV+CR, CR+CC and AUTO modes,
which can satisfy a wide range of test requirements.
•
CV+CC Mode
In CVCC mode, it has to program the constant voltage and constant current
first and then start the UUT for output. When the UUT voltage starts to out-
put, the Load will sink in CV mode according to the programmed voltage.
When the voltage rises to exceed the set constant current for sinking, it will
switch to CC mode for sinking.
The CV+CC mode can be applied to the load simulation battery and test the
charging station or the car charger. When the CV is working, the maximum
loading current is limited.
•
CV+CR Mode
In CVCR mode, it has to program the constant voltage and constant resist-
ance first and then start the UUT for output. When the UUT voltage starts to
output, the Load will sink in CV mode according to the programmed constant
voltage. When the voltage rises to exceed the set constant resistance for
sinking, it will switch to CR mode for sinking.
The CV+CR mode can be applied to the LED simulation and test the LED
power supply to get the LED current ripple parameters.
