Hi Guys ,
We designed a power supply for 3phase ,but the issue here is we are facing huge noise in the transformer and snubber part is getting heat even with the input voltage 200V AC.
One issue i found is when i measure my transformer leakage inductance(using LCR meter by shorting all secondary at a common point)i got 56uH but as per the PI recommendation leakage inductance should be 30uH.
Please find the attachment for schematic ,drain to source voltage and transformer design details.
Mod edit: moved from duplicate post. One per question, please.
