工作职责
Take part in SSCB project evaluations and technical feasibility studies. Propose hardware solutions for sensing and protection.Design current sensing circuits using Rogowski coils and current transformers. Competence of signal conditioning, isolated amplification, anti-aliasing filtering and ADC selection.
Design voltage sensing circuits, including high-voltage dividers and isolated sensing. Implement over-voltage, under-voltage and phase-loss detection.
Design fast hardware protection circuits, such as comparator-based microsecond-level short-circuit detection and di/dt detection. These circuits must detect short-circuit faults quickly and trigger trip.
Define protection logic together with software engineers. This covers trip characteristics such as long-time overload, short-time delay, instantaneous, ground fault and over-temperature protection. Agree how hardware and software protection divide and coordinate their tasks, and contribute to selectivity design.
Analyze and verify sensing accuracy, including error budget, temperature drift, linearity and calibration methods. Support energy metering and fault recording functions.
Own EMC and noise-immunity design for the sensing and protection circuits. The circuits must neither trip falsely nor fail to trip under strong electromagnetic interference.
Lead PCB layout reviews, with a focus on sensing signal integrity, separation of analog and digital ground, and high-voltage isolation distances.
Create and maintain complete design documentation as required, including schematics, BOM, design calculations, DFMEA and test reports.
Support type testing and certification to standards such as IEC 60947-2, UL 489 and IEC 61000-4-x, and drive any corrective actions.
Maintain products in series production, resolve design-related quality issues and support product lifecycle management.
Support cost and quality optimization, including component selection, validation of alternative components and technical communication with suppliers.
Interpret customer requirements, translate them into technical specifications and evaluate design concepts.
Coordinate with cross-functional and global teams to plan and manage R&D; projects.Complete other tasks assigned by the company.
