Two or more power supplies which are capable of constant
voltage or constant current automatic cross- over operation
can be connected in parallel to obtain a total output current
greater than one power supply. Total output current is the
sum of output current across all power supplies. The output
settings from each power supply can be made separately.
The control of output voltage for one of the power supply
should be set to the desired output value, while the other
power supply should be set to a slightly higher output
voltage. The power supply with higher output voltage setting
will deliver its constant current output and drop its output
voltage. This will happen until the output voltage equals the
output of the other supply, and the other supply will remain
in constant voltage operation; only delivering that fraction of
rated output current that is necessary to fulfill the total load
demand.
