Common Mistakes in DC/DC Converters and How to Fix …
www.ti.comseen in Figure 7 can be observed in inductors made from a hard saturating magnetic material like ferrite and operated above their saturation current limit. Other magnetic core materials that offer soft saturating profiles can be more forgiving in these situations. It is also recommended to check how the inductor saturation profile changes
CCM PFC Boost Converter Design - Mouser Electronics
www.mouser.comCrCM inductor are low HF core loss, low HF winding loss, and stable value over the operating range (the inductor is essentially part of the timing circuit), the CCM mode inductor takes a different approach. For the CCM mode PFC, the full load inductor current ripple is typically designed to be 20-40% of the average input current.
