Day 1 on the Power Electronics Engineer path.

What a Power Electronics Engineer does

Designs and tests circuits that convert and control electric power for products like chargers, motor drives, and inverters to make them safe, efficient, and reliable.

  • Design power converter and inverter circuits to meet voltage, current, and efficiency targets
  • Simulate circuits and magnetics to predict losses, heat, and stability before building hardware
  • Build prototypes and run lab tests for efficiency, EMI, thermal limits, and fault behavior
  • Select components like MOSFETs, IGBTs, drivers, capacitors, and inductors for cost and reliability
  • Create control strategies for switching, protection, and regulation across operating conditions
  • Work with mechanical and thermal teams to manage heat sinks, airflow, and packaging limits
  • Debug failures using measurements and root-cause analysis, then implement design fixes
  • Document designs, test results, and safety compliance evidence for reviews and production

A day in the life

  1. Review requirements, test results, and open issues, then plan the next lab and design tasks
  2. Run simulations, update schematics, and check key margins like voltage stress and temperature rise
  3. Spend lab time probing waveforms, tuning control loops, and measuring efficiency and EMI
  4. Meet with cross-functional teams to align on constraints, risks, and release timelines
  5. Write short reports and update design files so others can build, test, and manufacture reliably
