Designed and developed high-performance inverters for power drive systems used in electric vehicles for Hyundai Motor Corporation, resulting in improved efficiency and reliability. Participated in Six Sigma Green Belt (SSGB) certification and helped save USD 5290 per annum by reducing Viper power module switch noise in 2-pulse tests. Also participated in ISO26262 Functional Safety certification.

Designed and Developed 30kW DC-DC Electric Vehicle Charger (Two Stage) with a wide output voltage range (150-950V). - Implemented Vienna PFC rectifier + LLC resonant converter stages to meet the BOM cost of $1000 with a power density of 27W/in^3 and 96% peak efficiency. - Designed schematics for the charger and assisted ECAD for PCB Layout. - Verified functionality of the charger in Prototype 1 and Prototype 2 (further reduction in size) and supported engineers on EVT stage at the factory.

Designing a High Frequency (HF) step down transformer for a DC-DC converter to get a high output current and low output voltage. Calculating the possibility of the design with lower core area and analyzing the parameters such as flux density, losses and current densities using Finite Element Method (FEM) softwares. Testing the prototype and comparing the results with the simulations.

Peer to peer tutoring and providing feedback at any stage of writing or drafting process for assignments, projects, research papers, emails, conversational skills, etc.

Pursued Masters degree in Green Electronics from TUM-NTU joint degree program. The course is related to Microelectronics, which focuses on courses like Advanced MOSFET and Novel Devices, Green Nanotechnology, Micro fabrication Technology, Nanotechnology for Energy Systems and other courses related to Semiconductor Physics. Our coursework comprises of Master dissertation (6 months) and Internship (3 months). I am doing both my Dissertation and Internship in Rolls-Royce@NTU Corporate Lab.
