Leakage Inductance

Posted by: Tugay on Tue, 06/08/2021

Hi Friends,

I have designed 32V 7A SMPS using with Pıexpert. According to PIExpert, the transformer's leakage inductance should be 3.5uH, but I measure 7uH in the transformer I designed.

1. Is this a big problem for transformer design?

2. Will this problem prevent the circuit from working?

3.What kind of problems does a high leakage inductance cause?

4.The most important question is will the TOP259EN be damaged?

Thanks,
