Multilayer Inductor
An inductor constructed by layering the coil between layers of core material, the coil typically consists of a bare metal material( no insulation), this technology is sometimes referred to as "non-wirewound", the inductance value can be made larger by adding additional...
When we desgin the inductor, we ofter need select which core material shall be used,e.g. MPP, Senduse, Koo Mu,High Flux and Iron Powder, first we consider below these requirements:
1) DC Bias Current through the inductor
2) Ambient Operating Temperature and acceptable temperature rise. Ambient...
PFC inductor design
1, selection core:
We should be know below necessary information:
(a) Minimum Inductance based on DC basic, e.g. 1mH
(b) IDC current, e.g. 3A
According to formula LI*I= 1.0*3.0*3.0=9.0
We can find 60u is in range from curve which is LI*I vs core part number, and find...
