Experimenting with Inductors

3 Posts authored by: genebren Top Member
I have achieved my stretch goal of winding some torrid-base inductors and I would like to share those results.  Also, as a result of a comment on last blog by andrewj  (thanks!) concerning transient changes, I have done a bit more testing and sharing those results.   Background     Using the my old Micrometals toroidal powder cores that I found in one of my may parts boxes, I set out to wind my own inductors.  Having used the part number on the smallest of my toro ...
Again, I want to thank the element14 Design Challenges group for selecting me to be a sponsored contestant in the "Experimenting with Inductors" competition. I also want to thank KEMET for sponsoring this competition.   Background   How a DC-DC boost converter works A DC-DC boost converter operates based on the principles of the Inductor that provides the 'boost' for the circuit.  Here is a simplified circuit of a boost converter: In the circuit above, the boost chip contains a ...
The element14 "Experimenting with Inductors" Design Challenge sounded like a great opportunity to study the effects of the various parameters (inductance, DC resistance and rated current (Isat)) in a DC-DC Step-up regulator circuit.  I have designed several DC-DC Step-up Regulator circuits, including the power pack for my Movers and Shaker competition entry (WalkyII - Walky the Biped Robot - Power pack ). I saw this as an opportunity to dig a little deeper and explore a fuller range of the ...
