Principal/Senior Engineer - MV DC-DC Power Conversion
On-siteNürnberg, Bavaria, Germany
Job Summary
Formulate technical roadmaps for DC-DC power conversion subsystems within 10kV–35kV Solid-State Transformers, aligning with industry trends and customer demands across data centers, PV, energy storage, and EV sectors. Lead architecture design, simulation modeling, and key component design for medium-voltage high-power isolated DC-DC converters, including DAB, LLC, and CLLC topologies, while taking full accountability for R&D deliverables competitiveness. Manage Medium-Frequency Transformer design and address technical challenges in insulation, partial discharge suppression, and thermal management under complex operating conditions. Provide end-to-end technical support for frontline sales in strategic project development, prototype testing, and on-site consultation to drive key customer project closures. Collaborate with industrial research institutes and universities to incubate new technologies and facilitate mass deployment.
Required Qualifications
- Seasoned specialist in Solid-State Transformers (SST) and medium-voltage high-power isolated DC-DC conversion
- Proficient in topologies including DAB, LLC and CLLC as well as their control schemes
- Well-versed in Medium-Frequency Transformer (MFT) design
- High-voltage high-frequency insulation and partial discharge suppression
- In-depth research and hands-on development experience in high-voltage SiC device application
- Gate driver design
- Series voltage balancing control
- Skilled in the full hardware development workflow for medium-voltage high-power converters
- Proven project management capabilities
- Expertise in PLECS simulation software
- Capable of conducting electric field and magnetic field simulations to analyze electric field strength for medium-voltage insulation design
- Minimum 5–8 years of relevant industry experience
Desired Qualifications
- Proven successful development experience of medium-voltage (6kV/10kV/35kV) SST
