Job Description

Power Electronics Design Engineer – Traction Converter (P10)

Role overview

As a Power Electronics Design Engineer, you will be responsible for the detailed design, development, and validation of high-performance power electronic components and subsystems used in traction converter for EV power trains. You need to translate system-level requirements into schematics, prototypes, and production-ready designs, playing a key role in bringing cutting-edge power electronics solutions to life.

Key Responsibilities
- Design and develop power conversion circuits and modulesfor traction inverters, gate drive and protection circuits) based on system-level specifications and requirements.
- Perform detailed schematic capture, PCB layout guidance,



and component/device selection for high-efficiency power circuits.
- Perform simulation, analysis, and optimization of power stages, switching topologies, thermal performance, and EMI/EMC characteristics, filter design using tools such as LTspice, PLECS, and MATLAB/Simulink and hardware testing to validate designs.
- Design:
- High-voltage DC-AC traction inverter
- DC-DC converters in vehicle platforms
- Semiconductor selection (SiC MOSFET / IGBT modules)
- Gate driver circuit design (dv/dt immunity, Miller clamp, short-circuit protection)
- Switching loss & conduction loss modelling
- Thermal modelling and cooling strategy definition
- Magnetics and busbar design optimization
- Optimize design for motor control algorithms, various drive cycles like WLTP, MIDC
- Support EMI/EMC mitigation, thermal management, and protection strategy implementation.
- Collaborate with cross-functional teams (firmware, mechanical, testing, manufacturing) to
