o
Provide different current set point and observe the current flowing through the BOSS.
Confirm that the actual current follows the set point.
o
Once the test is complete, shutdown the BOSS using the shutdown command.
o
Discharge/Shutdown then disconnects the load.
Testing the Bi-directional Functionality of the BOSS Using a Single DC
Source
This test known as re-circulation allows the test personnel to use a single source to test the
BOSS in a bi-directional way. The test setup allows testing personnel to –
o
Perform high power tests for long duration.
o
Test how the BOSS follows the current set point.
o
Change the direction of the current flow on the fly.
On the other hand, since the input is connected to the output,
o
The voltages always will be the same on the BUS and the BATT side.
o
The test can be performed only when the BOSS is designed for a system where the
BUS and the BATT nominal voltages are relatively the same (I.e. 1:1 ratio).
Alencon performs this test using Magna Power Supplies. Below diagram shows the basic test
setup for bi-directional testing of the BOSS.
