Q: What’s Constant Voltage (CV)&Contant Current (CC)?
A: When you use a power supply you usually set the desired voltage and the maximum current. When you connect the load two things can happen:
(1)The load requires more current than the maximum you set.
(2)The load requires at most the maximum current you set.
In the first case the PSU become a current source: the current is limited to what you set and voltage drops accordingly, that’s CC for you. In the second case what is costant is the voltage, so that’s CV.
