Hi everyone, I am opening this subject because I would like to ask you some information about the coils designing. Indeed, I am working on a project which requires a coil, with an great deal of inductance, possibly close to 1H, and which can deal with a maximum current of 10 amps. I have already tried with a MOT transformer : I used its primary coil as an inductance and it works perfectly. However the weigh of the transformer bring some drawback and in that respect, I would like to design my own inductance to replace it. I have recovered a magnetic core from an old transformer, smaller than the MOT. I would like to use it to design my own coil. I have tried to wind the magnetic core in different way to make a coil with a suitable inductance but it did not work. I am wondering if my core is not saturated, but I don't have any implement to check that. Therefore, I would like to contact you, see if you could help me. I don't have enough information about the designing of inductance, especially by considering the saturation. |

Bonjour monsieur, désolé, impossible pour le bon réponse votre question, avant réception plus des informations. 10 ampères AC, DC ou les tous ? Fréquence min, max ? Linéarité ? J'attends pour votre réponses, Bon Soirée Jean-Paul |

Comment savez-vous que je suis français ? Je parle anglais si mal que ça ? :P Voici ce que je peux vous dire : Il s'agit d'un courant rectifié provenant d'un pont de diode lui même relié au 230 volts du secteur (donc 50Hz). Le courant est limité grâce à une résistance électrique de 23 Ohms, dont courant efficace maximum de 10 ampères. Je cherche à concevoir une inductance de l'ordre de 1 H. |

1H at 10A saturation current requires a physically massive and heavy inductor, no way around it. I suspect you can't get it much smaller than a microwave oven transformer. What are you actually doing? There's likely a better way which requires less or no inductance. |
