Inductor - 22uH : Implementation

Postby shadders » Tue May 23, 2017 9:12 am


With regards to the inductor of 22uH - the design uses what i assume is a toroidal core to create the inductor - increases the inductance per given number of turns.

I have not analysed the inductor behaviour, but i again assume that the toroidal core will have a specific B/H curve which although it may have a very low coercive force to magnetise the core, this will still introduce a non linearity to the circuit.

Was the inductor designed to have a small PCB footprint, hence the use of the toroid core ?.

If the PCB was redesigned for an air cored inductor, are there any design considerations or issues, in using an air cored inductor ?

I propose to use the following for a redesigned PCB :

TT Electronics : HA55L-3623220LF 22uH@100kHz, 34Amps power inductor.

Or a Jantzen air cored inductor.

Thanks and regards,
