Hi,
Cust has given us a not-working 500W PFC-FullBridge to get working.
They used two stacked HS-106160-2 torroids with 41 turns for PFC inductor.
Spec for PFC is 115vac, 60Hz, 220vout, 120khz, 550W
I find far less core loss is begotten when using the "same-size" MP-106169-2 or the MS-106160-2 torroids, and a more suitable inductance. (just different no of turns)
So why didnt the engineer use these better (for this application) torroids?
Are they more expensive?
HF-106160-2 torroid

..But the MP and MS versions are arent priced anywhere on the web.....how may we find out price?
