Power Electronics Design Engineer-Traction

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 test jigs for the testing of the products.
• Generate and maintain comprehensive technical documentation—including schematics, BOMs, layout files, design reports, validation records, and change logs—to ensure traceability and design integrity throughout the development lifecycle
• Support and participate in design reviews, DFMEA/DFM activities, and failure analysis investigations, contributing to the refinement of design standards and continuous improvement of engineering practices
• Ownership of design deliverables with strong communication skills, fosters effective collaboration across multidisciplinary teams, and maintains a commitment to continuous learning and engineering excellence.
