Intern, Power Electronics Engineer, Power Magnetics, Spring 2027

The role

You will support the design, validation, and characterization of magnetic components used in high-efficiency, high-power, and medium-voltage converter systems. You will work with power electronics engineers to validate inductors, transformers, planar magnetics, magnetic current sensors, and EMI filtering components.

What you will do

• Support the validation and characterization of medium-voltage magnetic components
• Assist in developing and executing test plans to evaluate magnetic performance
• Perform laboratory measurements using oscilloscopes, impedance analyzers, LCR meters, power analyzers, and thermal measurement tools
• Analyze switching waveforms to evaluate magnetic performance within power converter systems
• Support EMI/EMC validation efforts
• Assist with electromagnetic modeling and FEA simulations
• Help evaluate PCB layout and physical implementation
• Assist in building, assembling, and modifying prototype magnetic components and test fixtures
• Collect, analyze, and document experimental data
• Collaborate with power electronics, mechanical, and layout engineers

Required qualifications

• Currently pursuing a Bachelor’s, Master’s, or PhD in Electrical Engineering or related field
• Strong fundamentals in power electronics, including switching converter operation
• Understanding of electromagnetic and magnetic component fundamentals
• Familiarity with inductors, transformers, and magnetic materials
• Hands-on laboratory experience with oscilloscopes, multimeters, or similar test equipment
• Experience with circuit simulation tools such as LTspice, PLECS, or equivalent
• Strong analytical and problem-solving skills
• Ability to work in a hands-on hardware development environment

Nice to have

• Experience testing or characterizing magnetic components
• Familiarity with planar magnetics or PCB-integrated magnetics
• Experience with electromagnetic simulation tools such as ANSYS Maxwell, FEMM, or COMSOL
• Familiarity with EMI/EMC fundamentals and filtering techniques
• Understanding of parasitic inductance, capacitance, and high-frequency effects in power converters
• Familiarity with medium-voltage design considerations
• Experience working with magnetic core materials such as ferrite, nanocrystalline, amorphous, or powder cores
• Understanding of insulation coordination, creepage and clearance, and partial discharge considerations
• Experience with laboratory instruments such as impedance analyzers or power analyzers
• Familiarity with wide-bandgap devices such as SiC or GaN
