Hi Gotoluc,

Each L298N has two full H bridges. We parallel the H bridge to make a half bridge.You only need 15 boards and you have 30 half bridges.

Hi guys,

When comparing Pierre's shared program with 1->2 coils activation against real operation and his explanation in videos there is inconsistency about how many coils need to be activated at once and in what order. You can see my post in open thread about what is seen in recordings - http://overunity.com/17609/170-watts-in-1600-watts-out-looped-very-impressive-build-and-video/msg519057/#msg519057

Also the most important part is not in coils switching as Pierre mentioned. My bet is - he managed to make BEMF/interwinding induction recovery back to bank of supercapacitors of most energy spent and is not telling that. Also the Carlos Benitez patent No.17811 have strong relationship in what is causing extra energy there in my opinion.

Cheers!

What... I don't understand anymore!!!... I posted this video on page 3 of this topic showing 30 boards: https://youtu.be/3-HHaPDOWAM  and no one said anything. Now you're saying I need 18?

Can someone PLEASE make a Full diagram like I have asked for in the video.
I can build stuff but I need everyones help with the Aduino programming to work with the electronic circuit connections
I've just wasted 2 days soldering 30 boards.
I don't understand how 18 boards can control 30 coils?

Fr. Quoi ... Je ne comprends plus !!! ... J'ai posté cette vidéo à la page 3 de ce sujet montrant 30 L298N: https://youtu.be/3-HHaPDOWAM  et personne n'a rien dit. Maintenant vous dites que j'ai besoin de 18 ans?
Quelqu'un peut-il S'IL VOUS PLAÎT faire un diagramme complet comme je l'ai demandé dans la vidéo.
Je peux construire des choses mais j'ai besoin que tout le monde aide avec la programmation Aduino pour travailler avec les connexions de circuits électroniques
Je viens de gaspiller 2 jours à souder 30 planches.
Je ne comprends pas comment 18 planches peuvent contrôler 30 bobines?

Hi Gotoluc,

The schematic I sent shows how they are connected.

It true they don't have opto isolation.
I was looking at the specification of the opto isolated board version. However the diodes are either side of any one coil and clamped by the high capacitance of the rail capacitors, so there should be no voltage rise over rail.

I don't know what local transients there may be on the board, that will have to be checked.

I am only planning to run these boards at low voltage, then use the BTS7960 boards to run at 20-35V.

The enable jumpers  have to come off otherwise the outputs are always active.
