- Develop system requirements, functional specifications, and interface control documents (ICDs)
- Define electrical, thermal, mechanical, and communication interfaces




- Perform trade-off analysis (efficiency, EMI, cost, reliability, scalability)

2. Power Electronics Design
- Lead design of:
- High-voltage DC-AC traction inverter
- Onboard AC-DC converters
- DC-DC converters in vehicle platforms
- Semiconductor selection (SiC MOSFET / IGBT modules)
- Gate driver architecture (dv/dt immunity, Miller clamp, short-circuit protection)
- Switching loss & conduction loss modelling
- Thermal modelling and cooling strategy definition
- Magnetics and busbar design optimization

3. Motor Control & Drive Cycle Understanding
- Robust knowledge of:
- Field-Oriented Control (FOC)
- Torque & speed control strategies
- Regenerative braking integration
- Sensorless control techniques
- Understand and optimize performance across:
- WLTP drive cycles
