Tool/software:
Hello! I am currently building an SMPS using TI's design guide as a reference. 400- to 690-V AC Input 50-W Flyback Isolated Power Supply Reference Design for Motor Drives.
I have one question. The guide uses a ZD snubber, and I am curious about the method for selecting the RC values for the snubber. If there are any related documents, could you kindly share them?
Hi Seungpyo
Thank you for reaching out.
The following materials are good resources for designing the snubber.
Regards,
Harish
