Designed a Bidirectional Boost-Boost DC-DC converter for EIS in high-voltage battery systems. Achieved 97% simulated efficiency using multi-loop PWM control. Validated simulation through reduced-voltage hardware tests and developed scalable, cost-effective integration techniques. Final Thesis Grade: 1.0 (Sehr Gut).

Conducted SPICE simulations (SIMetrix, MATLAB) for EIS excitation and high-voltage DC-DC converter designs. Simulated Boost-Boost topologies under varied conditions to analyze switching losses and thermal behavior. Optimized design parameters for 800V battery systems and evaluated SiC and HV MOSFET performance for efficiency and hardware implementation.

Contributed to the Design Quality department, focusing on battery management systems for premium OEMs. Analyzed schematics and layouts of automotive products, conducted root cause analysis, and prepared 8D reports. Supported quality improvements by optimizing production performance and collaborating across teams.

Worked on energy storage systems with a focus on renewable energy. Tested lithium-ion batteries, BMS, EMS, and inverters. Conducted root cause analysis to improve system reliability. Supported troubleshooting, documented faults, and researched balancing circuits to enhance energy efficiency.
