Power Electronics Design (Magnetics)

Job Description

Role Overview

. We are seeking a proficient switch mode power supply design Engineer with strong expertise in power electronics, magnetic component design, and ANSYS Maxwell-based electromagnetic simulations. The domain will be development of onboard charger and DCDC for electric vehicles.

. The role involves full-cycle development of power converters, including modeling, simulation, prototyping, and validation.

Power Electronics Design

. Design AC-DC (11kW) and DC-DC SMPS (5kW) topologies such as Flyback, LLC, Buck/Boost, and PFC.

. Perform power-stage calculations, device selection, control-loop design, and thermal/derating analysis.

. Ensure efficient, reliable, and robust converter operation.

Proficiency in working with high Voltage (400V/800V) and high current(200A) applications.

Magnetics Design & Electromagnetic Simulation

. Design transformers, inductors, chokes, and custom magnetic components.

. Conduct ANSYS Maxwell or CST or COMSOL 2D/3D simulations, for magnetic fields, core & copper losses, parasitic extraction.

. Perform skin effect and proximity effect loss analysis in windings.

. Optimize magnetic components for performance, thermal behavior, and size.

Modeling, Validation & Lab Work

. Perform circuit simulations using LTspice, PSIM, PSpice, or MATLAB/Simulink.

. Build and evaluate hardware prototypes for efficiency, transient response, switching behavior, and thermal characteristics.

. Hands-on lab experience including oscilloscope measurements, power analyzers, LCR meters, and thermal imaging.

. Perform debugging, root-cause analysis, and iterative design refinement.

Compliance & Documentation

. Ensure compliance with IEC/UL/CISPR/automotive standards as applicable.

. Prepare schematics, BOMs, design reports, test plans, and validation documentation.
