Ferrite core size and number of turns for transformer design

Click For Summary

Discussion Overview

The discussion revolves around the design of a ferrite core transformer for a 100W, 4MHz class E amplifier, focusing on impedance transformation and load isolation. Participants share resources and guidance for transformer design, including books and web pages.

Discussion Character

  • Technical explanation, Homework-related

Main Points Raised

  • One participant seeks guidance on designing a ferrite core transformer due to a lack of knowledge in the area.
  • Another participant provides links to design guides and resources for transformer design with ferrite cores.
  • A suggestion is made to consider a Transmission Line Transformer, along with links to introductory materials and handbooks.
  • A later reply expresses gratitude for the shared resources, indicating they were helpful in starting the design process.

Areas of Agreement / Disagreement

Participants generally agree on the usefulness of the shared resources, but the discussion does not resolve the specific design challenges faced by the original poster.

Contextual Notes

The discussion does not address specific formulas or detailed design parameters for the transformer, leaving those aspects unresolved.

hello.
I'm designing a 100w 4Mhz class E amplifier. I need a ferrite core transformer for impedance transformation and load isolation but unfortunately I lack the knowledge required for designing it. if anyone could guide me to a good book or a web page, or simply give me some formulas I would be very grateful.

thank you.
