I am sorry that I was not clear in my post about the high voltage conductors at the secondary. This is what I meant: the secondary voltage can be 5 V or 10 V but with respect to a 10 kV reference. Thank you for your answer. (more) |

The number of layers can be 4. The secondary voltage is low (maybe 5 V or 10 V) but with reference to a 10 kV reference. (more) |

I was given this as a project to work on. The isolation requirement is 18 kV rms. The secondary side will be at a higher potential. This is just an initial design for my understanding. I will have to look into it much more than what I currently know. Thank you for your comment. (more) |

Everything seems to be clear now. I had a lot of confusion about why the magnetic flux density was so low even for multiple core cross-sections. Thank you for your answer. (more) |

In the link to the website that I posted, there is a graph that shows the desired flux density for various switching frequency values. At 400 kHz, the required flux density required to minimize core losses is specified to be close to 400 Gauss which is 0.04 T. Is this correct? (more) |

I have added a link to the core considered to the post. This specific topology is considered to ensure isolation between the supply and the load. I am in the process of creating an initial design for the transformer. The winding ratio is 1.5:1. I haven't selected the number of primary windings needed... (more) |

I have added units to all my equations. Would you please tell me if the saturation magnetic flux density is correct? In the link that I mentioned, it is approximately 0.04 T at 400 kHz for Ferrites. The area-product value is too low and doesn't make any sense. (more) |
