Conduct feasibility studies and architecture reviews for new technologies and product opportunities.
2. Magnetics Architecture & Design
Provide deep technical expertise and leadership for high-frequency power magnetics, including transformers, inductors, coupled inductors, planar magnetics and integrated magnetics.
Own or guide magnetic component design covering core material and geometry selection, winding architecture, turns ratio, inductance definition, leakage and magnetizing inductance.
Optimize core losses, copper and AC winding losses, skin and proximity effects, parasitic capacitance, isolation, thermal performance and saturation behavior.
Develop magnetics solutions optimized for high-frequency, high-efficiency and high-power-density power conversion.
3. Magnetics & Semiconductor Co-Optimization
Drive co-optimization of power semiconductors and magnetics at the converter/system level.
Understand the interaction between semiconductor switching characteristics and magnetic component design.
Evaluate trade-offs among switching frequency, semiconductor losses, magnetic losses, passive component size, EMI, thermal performance, converter efficiency and power density.
Define system requirements that enable optimum utilization of Silicon, SiC and GaN technologies.
Identify opportunities where advanced magnetics and power integration can create meaningful system-level differentiation.
4. Advanced Power Conversion
Provide strong technical expertise across relevant converter architectures such as:
Power Factor Correction (PFC)
Resonant converters including LLC / CLLC
Half-Bridge and Full-Bridge converters
Phase-Shifted Full Bridge and Dual Active Bridge
Multiphase and bidirectional converters
High-frequency isolated conversion and non-isolated DC-DC conversion
Evaluate emerging architectures and determine their applicability to future Data Center and Industrial power systems.
5. Modeling, Simulation & Hardware Development
Develop and guide detailed system-level and magnetic-component models.
Perform converter loss analysis, magnetic loss modeling, efficiency optimization, switching analysis, thermal analysis and control-loop analysis.
Develop or guide development of proof-of-concept and reference hardware.
Correlate analytical and simulation results with laboratory measurements and drive design optimization.
Establish design methodologies and guidelines for high-frequency power conversion and magnetics.
Experience with tools such as PLECS, SPICE, MATLAB/Simulink and FEM-based magnetic simulation tools is highly desirable.
6. Semiconductor Product Definition
Translate system and magnetics requirements into actionable semiconductor product requirements.
Collaborate closely with Product Management, IC Design, Power Device, Packaging and Application Engineering teams.
Provide system-level input for power semiconductor devices, power management ICs, controllers, gate drivers, integrated power stages, power modules and advanced packaging technologies.
Ensure semiconductor product definitions are driven by clear system architecture and end-application requirements.
7. Data Center & Industrial Applications

Identify new approaches to improve power density and converter performance.
Explore advanced magnetics and power-integration concepts.
Generate differentiated technical concepts and contribute to intellectual property and patents.
Collaborate with external technology partners, universities, research institutes and suppliers.
Evaluate new magnetic materials, manufacturing technologies and component architectures.
9. Customer & Ecosystem Engagement
Act as a senior technical interface with strategic customers and ecosystem partners.
Engage with customer System Architects and senior R&D engineers.
Understand current and future system-level challenges and translate them into system and semiconductor product requirements.
Lead technical workshops and architecture discussions.
Work with magnetics suppliers and technology partners to develop optimized solutions for advanced power-conversion platforms.
