The resonant choke

The inductance of the choke is 2.4 mH with a

minimum saturation current of 0.65 A. In the prac-

tical example it has been done with:

Core: Thomson LCC E2006 material B4;

Air gap: 2 spacers of 0.4 mm each (total 0.8 mm);

AL = 75 nH;

Bobbin: HC2006BA-06;

Number of turns: 175;

Measured saturation current: 1 A peak @ 25 °C;

Customization of the board

Some flexibility is added to the board to extend its

evaluation. The MOSFETs have two foot prints to

mount either I-PAK or TO220 packages. And two

choke footprints are also avalaible for E1905A

and E2006A magnetic cores.
