Hi,
Doing Current sense transformer for 1000W Boost PFC with UCC28070A.
E20/10/6 core
Primary = one turn of TEX-ELZ 7/0.3mm
Secondary = 50 turns of 0.2mm TEX-E
Is the primary to secondary coupling good enough in the attached? (seen from four angles)
I cannot see what insulation is on the 1T. I might use Tripple insulated wire. Will that winding move if force is applied? The isolation should be as good as any Primary to Secondary windings.
Thanks, yes it could move, though this is prototype only, just to demo 180V at 2kW and nothing else. The use is as on pg 1 of the UCC28070A datasheet. UCC28070A
I tried to do another CST with ECW, but its horrendous to solder to the pads on the PCB....The TEX-ELZ TIW is solderable and was far easier to terminate.
As you know, TEX-E and TEX-ELZ are triple insulated wires.
