(NOTE: STILL EDITINGSEE BOTTOM OF PAGE FOR VALIDATION RESULTS (FOR SOME OF THE TESTS)
This page will go over the test plans for the solar sense board and all the unit/integration tests for each subsystem implemented. It will be written out based on what to populate, then subsequently what to test so we populate only the subsystems we need to.
...
LV isolation reverse bias
HV isolation reverse bias
Voltage drop across diode all cases
Thermals (shouldnt be anything significant)shouldn't be anything significant)
The following will outline my testing of the ideal diode:
I populated everything as instructed above
I first wanted to ensure the forward bias works. The following table outlines the drop across (everything without load btw) the diode based on the output and input. Note, the table only has forward bias testing, where no power supply was loaded onto the cathode.
Voltage on the anode (V) | Voltage on the cathode (V) | Drop across the diode (V) |
|---|---|---|
4.19 | 3.908 | 0.282 |
9.02 | 8.95 | 0.07 |
12.99 | 12.94 | 0.05 |
16.55 | 16.51 | 0.04 |
29.95 | 29.93 | 0.02 |
31.33 | 31.31 | 0.02 |
Now I want to test the reverse bias protection to make sure that when i put a supply on the cathode, it will not conduct to the anode. The following table summarizes my results, and note that once again there is no load.
Voltage on the cathode(V) | Voltage on the annode(V) |
|---|---|
2.256 | 0.172 |
9.68 | 0.360 |
19.95 | 0.475 |
29.99 | 0.571 |
31.36 | 0.583 |
31.38 | 0.592 |
The ideal diode works!! that was the smoothest validation so far → ideally id test with higher potentials, but considering that this testing was above the rating of the zener diodes already, it’s safe to say it operates as intended. Of course, double checking with a potential of over 100V would be ideal before integration testing (in which case I can finish filling out these tables).
