Hi guys,
Quick question about the SRF of a transformer. How does the SRF specification effect the design of a power supply. For instance if a transformer is designed to switch at 100KHz and the SRF of the transformer is 150KHz how would you know the following:
1) Whether the SRF is too close to the switching frequency.
2) If it is too close, what effects would you be likely to see.
3) What are the main external aspects within a design that can affect the SNF of a transfomer, i.e input ripple caps (if there are any aspects that do)
4) Does the core contribute/effect the SRF?
Many thanks in advance
