Design the medium-frequency transformer at the heart of every SST cell: hundreds of kilowatts at tens of kilohertz, insulated for tens of kilovolts DC to ground.

Responsibilities

Design the medium-frequency transformer at the heart of every SST cell
Choose core materials, winding structures, insulation, and liquid cooling that balance loss, size, and cost across thousands of units
Prove each design on the bench with hi-pot, partial-discharge, impulse, and thermal-cycling tests, and set the acceptance tests every production unit must pass
Review vendor transformer designs during co-development and sign off on their insulation margins before we commit to volume
Turn the design into a part a supplier can wind, pot, and test at volume, and qualify a second source

Requirements

Nice to have: Core materials (nanocrystalline, ferrite)
Nice to have: Solid and cast insulation (epoxy, silicone potting)
Nice to have: Magnetics FEA (ANSYS Maxwell, COMSOL)
Nice to have: Integrated leakage design for resonant converters (LLC, DAB)
Nice to have: Transformer and insulation standards (IEC 61558, UL 1446)
