6.4.5 Complex Operation Mode

Complex operating modes include CV+CC, CV+CR, CR+CC, CV+CP and
AUTO modes, which can satisfy a wide range of test requirements.
⚫
In CV+CC 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 output,
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.
⚫
In CV+CR mode, it has to program the constant voltage and constant resistance
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.
