Full Job Posting
- Lead the topology selection, component specification, and schematic design of the HTS Magnet PSU.
- Design modular power converters with potential for arrayed operation and independent control.
- Analyze and simulate power converter behavior (steady-state, dynamic, fault response) using PLECS, LTspice, or Simulink.
- Integrate with embedded control hardware and firmware, ensuring proper current regulation, fast feedback, and fault handling.
- Define and implement magnet protection mechanisms, including overcurrent shutdown, fast discharge, and crowbar circuits if needed.
- Design thermal management systems, including heat sink layout, forced air/water cooling, and temperature monitoring for continuous operation.
- Design PCB layout and support mechanical integration, cabling, and in-house assembly.
- Develop test plans and perform hardware bring-up, debugging, and parameter optimization under staged load conditions.
- Bachelor’s or Master’s degree in Electrical Engineering, Power Electronics, or a related field.
- 5+ years of hands-on experience designing and testing power converters, preferably in high-current or magnet power supply applications.
- Proficiency in power stage design for DC/DC converters, buck/boost, full-bridge, or current-regulated linear stages.
- Strong simulation and modeling skills using tools such as PLECS, LTspice, PSIM, Simulink, or Simplorer.
- Experience with IGBTs, MOSFETs, SiC/GaN devices, and high-current busbar and interconnect layout.
- Familiarity with current sensors, signal conditioning, and analog control circuits.
- Experience with magnet power supplies, fusion, accelerator, or industrial high-current systems.
- Knowledge of quench detection, crowbar protection, and superconducting magnet interface requirements.
- Experience with thermal design and integration of cooling solutions in power electronics.
- Exposure to EMI/EMC mitigation strategies and compliance testing.
- Familiarity with FPGA- or DSP-based digital control systems.
- Simulation: PLECS, LTspice, PSIM, Simulink.
- CAD: Altium Designer, OrCAD.
- Measurement: Oscilloscopes, Power Analyzers, Electronic Loads.
- Communication: CAN, RS-485, Modbus.
