Figure 29 Relationship Between CV/CC Mode and Load
7.5.3.2 CV Priority Mode
Under CV priority mode, the control system will initially set current to the set value
and set voltage to 0V. The voltage will continue to rise. During this process, the
voltage is always regulated, with fast rise time and minimum overshoot performance.
When supplying power to high impedance loads under CV priority mode, the power
supply will always remain in CV mode. In this case, voltage overshoot is rare.
When supplying power to low impedance loads under CV priority mode, the voltage
cannot reach the set value due to low impedance. On the contrary, the current will
quickly reach the set value. And then CV mode is converted to CC mode, which may
cause unstable current control during the conversion process, and current overshoot.
