CONCORD CONTROL SYSTEM LTD.

Job Description

Design Engineer – Power Electronics

Department - Engineering / Power Electronics

Reporting To - Senior Power Electronics Design Engineer

Position Summary

To undertake detailed design, analysis, and validation of high power converters, inverters,

choppers, and rectifiers for applications in rolling stock and associated industries. The role

involves ensuring optimal system performance, reliability, protection coordination, and

seamless integration with mechanical structures and control systems across the product

lifecycle - from concept development to prototype validation.

In addition, the role includes developing, defining, and validating control philosophy and

operational logic for power electronic systems. This involves translating system

requirements into robust control strategies to ensure safe, reliable, and optimized

operation across all operating conditions.

Key Responsibilities

Design and development of high power converters, inverters, choppers, and rectifier systems

Application of power electronics systems in rolling stock, rail traction, and associated industrial applications

Integration of energy storage systems (battery-based or hybrid systems) with power electronics architecture

Perform detailed simulation and analysis using tools such as MATLAB/Simulink, PSIM, and PSpice

Conduct switching analysis, harmonic analysis, and system efficiency optimization

Develop and implement protection schemes, interlocks, and coordination philosophy

Develop control philosophy, operational logic, and functional requirements for converter systems

Define PWM strategies, switching sequences, and modulation techniques

Coordinate with firmware/embedded teams for control implementation and validation

Carry out electrical validation and performance verification of designed systems

Prepare detailed Bill of Materials (BOM) aligned with system design

Support prototype development, including assembly coordination and debugging

Participate in testing, validation, commissioning, and performance assessment

Identify design and control issues and implement corrective and optimization measures

Collaborate with cross-functional teams including Mechanical, Control, Manufacturing,and QA

Ensure adherence to applicable standards, safety norms, and quality requirementsKey Interfaces
