Battery power tool PSOC+MV GaN Evaluation and loss calculation - Shenzhen, 深圳, China
Originally posted 22 October 2026 by the employer.
Evaluation and loss calculation for battery power tool inverters using PSoC microcontrollers and medium-voltage GaN devices.
About the role
This internship role focuses on evaluating battery power tool motor drives using PSoC microcontrollers and medium-voltage GaN devices alongside inverter loss calculation. The work centers on modeling inverter and motor dynamics under trapezoidal and FOC control, as well as benchmarking against Si MOSFET baselines.
What you'll do
- Build PLECS models for inverter and motor systems under trapezoidal and FOC control.
- Implement Si MOSFET baseline and GaN device models, applying FOC for GaN devices.
- Define representative operating points for battery power tool applications, including speed, torque, and load conditions.
- Run loss simulations and extract detailed inverter loss breakdowns.
- Set up hardware tests on battery power tool setups to capture operational efficiency data and correlate simulation results with experimental measurements.
- Calculate motor losses to distinguish motor versus inverter loss contributions.
What you'll need
- Current enrollment as an undergraduate or graduate student in Electrical and Computer Engineering (ECE).
Nice to have
- Hands-on experience with circuit design.
- Familiarity with PLECS or FEA simulation software.
- Completed coursework in Power Electronics.
Skills: PLECS, GaN, inverter, FOC, loss calculation
