PCB Design Engineer, Power Stage Hardware

Skills

About the Role

You will design power stage and gate-driver boards for every solid-state transformer cell, including SiC half-bridge modules, isolated gate drivers, auxiliary power and sensing. You will lay out boards for fast-switching SiC with low-inductance loops and high-voltage creepage and clearance, bring boards up on the bench, and hand off manufacturing-ready packages.

Requirements

• Designed and brought up gate-driver and power-stage boards for SiC or GaN converters at hundreds of volts and above
• Laid out boards switching at high dv/dt without false triggering
• Designed isolated power supplies or signal isolation for high-voltage floating circuits
• Met creepage and clearance requirements and passed hipot test
• Taken a board from schematic to contract manufacturer and fixed first article failures

Responsibilities

• Design power stage and gate-driver boards for every SST cell
• Lay out boards for fast-switching SiC with low-inductance commutation loops and proper creepage and clearance
• Design isolated auxiliary power and signal links for boards floating at high voltage
• Bring up boards on the bench with technicians and test engineer and close design spins
• Hand off manufacturing-ready packages to contract manufacturers

Benefits

• Equity in the form of restricted stock units
