Chapter 3 Constant Current Tests

Preparation
The main parameters of the power supply requiring test under constant current
include constant current load adjustment rate, constant current linear adjustment
rate, ripple and noise as well as programming and readback accuracy.
Connect the devices recommended in Recommended Test Devices according to
the figure below under normal temperature (about 25
℃
). Note that a current
monitoring resistor (R=0.1Ω) should be connected between the power supply under
test and the electronic load serially to convert the current signal under test to voltage
signal for the measurement of related parameters.
