"Investigating The Impact Of Transformer Design on EMI Behavior In Flyback Converter" Researched EMI/EMC optimization in flyback converters with a focus on transformer design and its impact on common-mode (CM) and differential-mode (DM) noise. Developed LTspice simulation models to analyze switching behavior, parasitic capacitances, and noise propagation. Compared diode and synchronous rectification regarding their influence on EMI characteristics.

Designed a GaN-based QR Flyback Converter, covering electrical design, component selection, PCB layout, sourcing, assembly, testing, and validation. Performed EMC debugging, filter design, and optimization for EN55032 Class B compliance. Conducted EMC testing using LISN, EMI receivers, oscilloscopes, and near-field probes, supporting CE, RE, CI, RI, ESD, surge, and burst evaluations while collaborating with EMC engineers to validate designs and ensure EMC compliance.

Designed and developed a high-voltage DC/DC converter to supply low-voltage vehicle systems from the HV battery. Maintained and optimized the high-voltage powertrain, improving system reliability and performance through diagnostics and fault analysis. Supported powertrain development, testing, and validation by executing test protocols to meet safety and performance requirements. Used Altium Designer, LTspice, and MATLAB/Simulink.
