• Basic Info:

    While working for a passive magnetics manufacturer, I began to collaborate with one of our customers to create a wireless power transfer coil package designed to fit in the grip of a modern police-issue handgun.

  • Project Info:

    Per the customer's specifications, I calculated inductance of the primary and secondary coil geometries using EM power transmission guidelines, and the power regulator chip manufacturer's coil design guidelines. I proposed several packages for the coil, along with circuit footprints, measurements, and manufacturing optimizations using industry standard leads and commonly sourceable ferrites. Each proposed design favored either cost, dimension, or maximum delivered power for the component.
