Master’s Thesis Title: Comparative Study of DC Bus Architectures for Electric Aircraft Including Integration of Solid-State Circuit Breakers • Proposed eight DC bus architectures for a 4 MW distributed electric propulsion system. • Implemented 3L-NPC inverters, DC-DC boost converters, and solid-state circuit breakers (SSCBs). • Conducted load flow, DC fault, and reliability analysis. • Designed and implemented a coordinated control scheme for SSCBs. • Built a Python tool for trade-off analysis.

• Worked on HVDC system design, fault propagation, and protection systems for distributed propulsion systems. • Comparative analysis of inverter topologies. • Identification of EMI sources in inverters. • Worked on the power electronics lab bench. • Worked on BMS for aircraft applications. • Worked with DO-160 and MIL-STD-704 standards. • Showed results and collaborated with the project's members.

• Worked with a simulation model of grid-connected AC–DC rectifiers for electrolyzer applications. • Closed-loop and droop control in MATLAB/Simulink. • Worked with Grid-forming converter topologies for frequency and voltage stability in weak-grid. • Presented technical findings to project members and contributed to design decisions across the project lifecycle.

• Unit tests of a 5-winding transformer and fault propagation behavior in PSCAD. • Short-circuit analysis in a 3-phase AC system. • Used GitLab and Fork for version control and collaboration with project members.

• Performed circuit simulation using LTspice. • Set up test benches and performed hardware testing. • Designed and bench-tested a DC-DC buck converter in KiCad. • Worked with microcontrollers (STM32 platforms) for prototype development. • Documented experimental results to support ongoing departmental research projects.

• Conducted regular system audits and vulnerability assessments against cyber threats. • Implemented security protocols to mitigate unauthorized access.

• Completed structured industrial training across steam turbine operation, gas engine power plant operation & electrical maintenance, and I&C/generator/substation divisions. • Observed National Grid Control Room dispatch and monitoring operations.
