Figure 3-12. Auto-Parallel Operation

Setting Voltage and Current. Program the slave unit's output voltage above the master's to avoid interference with master- unit CV control. The slave unit's mode switches disable the slave unit's digital current setting from having any effect in auto- parallel operation. Program the master unit to the desired output voltage and 50% of total current. Verify that the slave is in CC operation.

When in CV operation, the master unit's voltage setting is the output voltage of the auto-parallel combination. The output current is the total current from all units. The fraction of total current that each unit provides is the same as the ratio of that unit's output current capability to the total output current capability of the auto-parallel combination.

In CC operation, the user must add up the current outputs from each unit and adjust the master until the total equals the desired load current.

Overvoltage Protection. Adjust the desired OVP shutdown limit using the master unit's OVP ADJUST control. Set the slave unit's OVP limit above the master's. When the master unit shuts down, the master programs the slave unit to zero voltage output. If a slave unit shuts down (because its OVP shutdown limit is set lower than the master's), it shuts down only itself, and the other unit supplies all the load current. The shut down slave unit will draw some current through its down programming circuit. The extra current required from the master may cause the master to switch from CV to CC mode.

Remote Sensing. To remote sense with auto-parallel operation, connect remote-sense leads only to the master unit according to the instructions under “Remote Sensing”.

Note: Down-programming speed is slower with auto-parallel operation because only the master unit's down programmer operates.

Series Operation

Up to two supplies can have their outputs connected in series to provide increased output voltage. Multiple loads may be connected in series, and the combination may be grounded at any one point to provide both positive and negative outputs. Regardless of whether or where the load is grounded, no point may be at a greater potential (+ or -) from ground than that specified on the output label on the rear chassis.

Caution: It is not recommended that Agilent 6015A supplies be connected in series. If you do so, the common connection between the two supplies must be connected to earth ground (see Figure 3-13).

Add the voltage settings of each power supply together to determine the total output voltage. Set the current limits for each power supply to the maximum that the load can handle without damage.
