j'ai un devoir pour la semaine prochaine ,aidez-moi svp pour tracer: (I have a homework for next week please help me to draw: )
1) Uc et is1 ..''si on court circuiter D1 et D5 '' (Uc and is1 if short circuit the diodes D1 and D5'')
2)Uc et is1 ..''si on élimine D1et D5 '' (Uc and is1 if D1 and D5 are removed)
3)Uc et is1 ..''si on ajoute une diode de roue libre Drl en parallèle avec la charge dans les 3 cas suivantes : (Uc and Is1 if we add a freewheel diode DRL parallel with the electrical charge in the following three cases: )
a)Pd3 simple. (Simple pd3)
b)si on court circuiter D1et D5.(if short circuit D1 and D5)
c)si on élimine D1et D5 .(if D1 and D5 is removed)
Note: La charge est purement inductive. (The electrical charge is purely inductive)

Post a schematic, svp. We have no idea what Uc is or where the diodes connect.
