Traction Inverter Projects

• Developed Model-Based Design (MBD) algorithms for traction inverters, specializing in Field-Oriented Control (FOC) systems with field weakening (FW) mechanisms and motor parameter estimation algorithms using MATLAB Simulink.
• Led software verification and testing for traction inverters, utilizing Power Hardware-in-the-Loop (PHIL) and real motor test benches for validation, ensuring alignment with vendor benchmarks.
• Gained expertise in system modeling and signal processing using VISU-IT, Maestra, and Simulink tools, along with calibration using ETAS.
• Played a key role in knowledge transfer from vendors to the company, equipping the team with technical expertise for future implementations.

2-in-1 OBC-DCDC Project

• Developed and implemented Power Factor Correction (PFC) systems for On-Board Chargers (OBC), successfully designing and simulating single-phase and three-phase PFC in MATLAB, generating embedded code, and integrating it with BSW stacks for flashing onto Infineon TriCore MCUs for signal testing.
• Led knowledge transfer efforts to integrate AUTOSAR architecture and standards into the system.
• Currently working on bidirectional OBC functionality for Vehicle-to-Grid (V2G) and Vehicle-to-Load (V2L) applications, contributing to system architecture and algorithm development.
• Exploring the transition from a two-stage to a single-stage OBC system by researching suitable topologies and developing simulation models in Simulink.
• Collaborating with cross-functional teams to analyze system specifications, ensuring robust and efficient design solutions.
• Completed ASPICE and ISO 26262 training, ensuring compliance with automotive software development and functional safety standards.
