CHAPTER 7 LOAD CONNECTION DESCRIPTION
33
7-4-2. Description of constant voltage curve
When the power supply acts to maintain its output voltage constant in spite of changes in load, line, temperature, etc.
Thus, for a change in load resistance, the output voltage of this type of supply remains constant while the output
current changes by whatever amount necessary to accomplish this. (As follows)
7-4-3. Description of Constant Voltage/Constant Current (CC/CV) curve
A power supply acts as a constant voltage source for comparatively large values of load resistance, and it also
functions as a constant current source for comparatively small values of load resistance. The automatic crossover or
transition between these two modes of operation occurs at a "critical" or "crossover" value of load resistance Rc =
Es/Is, where Es is the front panel voltage control setting and Is is the front panel current control setting.
