Description
When the power supply is operating in constant
current mode (CC) a constant current will be
supplied to the load. When in constant current
mode the voltage output can vary, whilst the
current remains constant. When the load resistance
increases to the point where the set current limit
(ISET) can no longer be sustained the power supply
switches to CV mode. The point where the power
supply switches modes is the crossover point.
When the power supply is operating in CV mode, a
constant voltage will be supplied to the load, whilst
the current will vary as the load varies. At the point
that the load resistance is too low to maintain a
constant voltage, the power supply will switch to
CC mode and maintain the set current limit.
The conditions that determine whether the power
supply operates in CC or CV (VSET), the load
resistance (RL) and the critical resistance (RC). The
critical resistance is determined by VSET/ISET. The
power supply will operate in CV mode when the
load resistance is greater than the critical resistance.
This means that the voltage output will be equal to
the VSET voltage but the current will be less than
ISET. If the load resistance is reduced to the point
that the current output reaches the ISET level, the
power supply switches to CC mode.
Conversely the power supply will operate in CC
mode when the load resistance is less than the critical
resistance. In CC mode the current output is equal to
ISET and the voltage output is less than VSET.
