Transformer
These are just a pain to understand
Larger transformers increase hysteresis loss.
The correct frequency is critical. Ideally, the frequency should be as low as possible without saturating the transformer. Higher frequency increases hysteresis loss.
Materials
- Laminated Iron Alloyws: 1.5-2.0T 50Hz-1KHz
- Powdered Iron: 0.6-0.8T 1KHz - 100KHz
- Ferrites: 0.25-0.5T 20KHz - 20MHz
Higher tesla is associated with higher core losses, but also higher saturation.
DIY Tests
- epoxy and magnetite
- epoxy and ferrite (Fe2O3)
- laminated steel plates
