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 ensure seamless integration and validation of designs.
Provide inputs for concept design, packaging and development of the product.
Support prototype bring-up, lab testing, and power bench measurements while driving root cause analysis and iterative debugging during validation, field trials, and production ramp-up
Develop tes
