Are you planning on making one? What are the details?

Vous comptez en fabriquer un ? Quels sont les détails ?

yes I plan to make a THREE-PHASE solar inverter that will convert a 12v DC voltage into a THREE-PHASE 380V -50Hz voltage

 

What's the application?
I can't think of many small three-phase loads apart from fractional-horsepower motors, and if you are driving a small motor, a VFD (that's a Variable Frequency Drive, not a Vacuum Fluorescent Display) might be more worthwhile;
and if you have a large three-phase load, then 12V is not the place to start.

OK. I have a 1.5Kw three-phase asynchronous motor that I want to power with a solar installation

 

Thats’s at least 125A @ 12V - that will cost a lot in cables!
How have you ended up with 12V? Every solar panel I have seen >300W has an output of around 40V.
Motor drive circuits are simpler than inverters as you do not have to produce A sinewave output: the motor will do the filtering for you.

 

Merci beaucoup... le truc c'est que je viens de donner une candidature par hasard sinon je voulais faire ça pour mon permis et je serai ravi si vous m'aidez à trouver une candidature simple pour ma réalisation

C'est au moins 125A @ 12V - cela coûtera cher en câbles !
Comment en êtes-vous arrivé au 12V ? Chaque panneau solaire que j'ai vu> 300W a une sortie d'environ 40V.
Les circuits de commande de moteur sont plus simples que les onduleurs car vous n'avez pas à produire une sortie sinusoïdale : le moteur effectuera le filtrage pour vous.

Qu’est ce que “mon permis”?
What do you mean by “mon permis”? Google’s translation doesn’t look right. . .
Do you already have your motor? Does it run continuously?

Thank you very much... the thing is, I just submitted an application by chance, otherwise I wanted to do this for my license and I would be thrilled if you could help me find a simple application for me to complete.

 

Can I ask, what's been your most complicated electric project so far (succesful one) that you have made?

 

And while at it have you made any power supply circuits like this?

You might want to start out with a lower power/lower voltage project. Generally, the higher the power the more expensive the learning curve.
