Key Responsibilities

• •System Performance & Simulation
• Develop and apply electrical and system-level models to predict power electronics performance, evaluate operating conditions, identify design limits, and guide architecture and component decisions.
• •Component Selection & Optimization
• Lead analytical selection and sizing of critical electrical components including power semiconductors, DC-link capacitors, bus structures, contactors, protection devices, filtering components, sensors, and supporting power conversion hardware.
• •Electrical Architecture & Integration
• Translate machine requirements into electrical architectures, component requirements, interface definitions, operating envelopes, and design constraints for MVPE systems. Partner with controls, electrical, mechanical, thermal, validation, and machine integration teams to optimize system-level performance.
• •Application Engineering
• Analyze machine duty cycles, voltage and current requirements, transient conditions, thermal loading, fault conditions, and other application requirements to ensure power electronics solutions are appropriately sized and applied.
• •Design Trade Studies
• Lead technical trade studies evaluating architecture, topology, component technology, performance, efficiency, thermal capability, reliability, packaging, cost, and system implications. Use analytical results to provide clear recommendations and influence design direction.
• •Validation & Model Correlation
• Define performance requirements and validation methods, correlate analytical models to laboratory and machine test data, investigate performance gaps, and improve simulation fidelity throughout development.
• •Technical Leadership
• Serve as a technical resource for power electronics analysis and application engineering, coach engineers in simulation and analytical methods, and help establish reusable models, analysis methods, design guidelines, and engineering best practices.
• •Cross-Functional Development
• Collaborate with global engineering teams, suppliers, manufacturing, validation teams, and machine programs throughout concept development, NPI, validation, and production implementation. The existing MVPE role definition similarly places importance on supplier collaboration, NPI, DFMEA, APQP, and production readiness.
