Hi,
We received an SMPS with PFC. It was 150W, 90-265vac.
The PFC inductor was several (four) equal_inductance offTheShelf smaller inductors in series.
Sounds like a great way to do it cheap..but surely all those switching nodes being at each inductor to inductor space...surely very difficult to pass high frequency common mode conducted emissions and radiated emissions?
