Figure 2-2 Connecting units in series
Parallel connection
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.
