- Perform stress analysis, component selection, magnetic design, schematic creation, circuit design, and PCB layout
- Conduct trade studies for key decisions such as circuit topology, power device, and magnetics
- Simulate power converters and basic converter control algorithms using MATLAB/Simulink, PLECS, LTSpice, and other tools
- Analyze structures and magnetic components such as bus bars and high-frequency transformers/inductors
- Design EMI/EMC filters
- Interact with suppliers on critical components
- Test prototype power electronics circuits in the lab
- Characterize power semiconductor devices, including Silicon, SiC, and GaN
- Engage with multiple cross-functional teams, including Mechanical, Software and Controls, Systems, Test, Quality, Reliability, and Manufacturing
Qualifications
- M.S. in Electrical Engineering with 5+ years of relevant industry experience, or Ph.D. with 3+ years of industry experience specializing in power electronics
- Familiarity with common 1/3-phase topologies such as AC-DC PFC Rectifier, and Isolated DC-DC converters (e.g., dual active bridge, LLC, etc.)
- Expertise in high-power EV charger or energy storage, stationary-related power converters
- Solid understanding of power semiconductor switches and diodes, and their characteristics
- Strong experience designing and optimizing power converter circuits including gate drivers
- Experience with digital control of power electronic circuits such as power stage average/small-signal modeling, closed-loop control, and PWM modulations
- Experience with bidirectional AC/DC or DC/DC power conversion
- Experience using software tools such as Spice, PLECS, Ansys, and MATLAB
- Experience of magnetic design, circuit parasitic analysis using FEA simulation tools such as Ansys Maxwell/Q3D or equivalent
