Larger update for all v9-3r users!
This release includes a fresh export from many important files and adresses most points in the #10 issue.
Changes
General
I've decided to discontinue the German versions of the Documentation and the Build Guide, as it is too much work to update both.
Also some additional copies of tables in the csv and ods format are removed, as xlsx is preferred in most cases (some csv will remain depending on application).
The date format is mostly changed to YYMMDD, because everything else is just confusing in international terms.
Documentation
| Change |
Page |
| Corrected transformer primary windings number from 28 to the actual 29 windings (confirmed by measurements) |
45 |
| In the cross-section of the primary winding on page 16, the arrangements of turns 11, 12 and 13 have been shifted one position to the left to match the photos in the build guide. |
46 |
| Note when inserting the TL431 simulation model. Change of a character required. |

Build Guide
| Change |
Page |
| Corrected transformer primary windings number from 28 to the actual 29 windings (confirmed by measurements), corrected drawings. |
14/17/33 |
| New Isolator design with alternate version for existing replicas |
14 |
| added link to transformer_README.md |
15 |
| Video on winding the primary coil added. |
17 |
| Images and video showing the design of the secondary coil added. |
19/20 |
| Added note, that the adhesive for gluing the cores must be rated for at least 100°C with a recommendation of 3M DP 760 and Chip Quik EGGSS1100CC--2200GG. Removed note of not gluing the isolator to the core (is mandatory now) see page 24 |
21/24/27 |
| Moved parts from chapter 7.8 (now 8.13) on gluing components after the performance tests. Some components must be glued to ensure that the converter complies with the FS rules. |
28/44/45 |
| Alternate HV connectors (J1.1 / J1.2) removed because they are not positively locked; HV input connector changed, see BOM/Kicad to Molex 43650-0315 (alternatively Würth 691416600002 for v9-3r boards before this release). |
28 |
| Changed Date format to YYMMDD |
51 |
| In the cross-section of the primary winding on page 16, the arrangements of turns 11, 12 and 13 have been shifted one position to the left to match the photos. The last image on page 18 has been rotated to match the orientation of the other images. Added note on page 19 regarding the rotation of the primary coil. |
16/18/19 |
| Added fix for CAN Interferences If used with AMK Racing Kit to the troubleshooting section |
30 |
| Plastik 70 replaced by Plastik 70 Super, as no longer recommended for Formula Student. Pro tip: Plastik 70 Super is UV fluorescent. A UV-flashlight can be used to detect complete coating. Listed fuses for masking before coating. |
13/25 |
| Important Change of the process for setting the minimum switching frequency based on a Git Issue. |
35/36 |
Scrutineering Support Presentation
| Change |
Slide |
| Fixed UVP Voltage threshold |
2 |
| Replaced U1, made voltage rating units more clear |
5 |
| Corrected transformer primary windings number from 28 to the actual 29 windings (confirmed by measurements). |
5/6 |
| Replaced Adhesive for transformer parts |
7 |
| Replaced J1 |
13 |
| Added section about the compliance with EV 4.5.15, added adhesive location and adhesive test video |
14/15/16 |
