12.2023 - Current
- Designed coupled inductor and integrated inductor for multiphase interleaved converter as a part of new product development with 33% reduction in BOM cost and 40% system level space reduction
- Proposed a novel architecture for integrating multidirectional power flows between 48V system, Ultra capacitor module and actuator which is currently in patentability study
- Created MOSFET models in SABER for behavioural study which simplified MOSFET selection process and reduced DV testing time by 40%
- Developed novel current sensing technique for solid state power distribution units utilizing the solid state device without additional circuit and ensuring maximum accuracy which is in patentability study too and a stepping stone for potential RFQ win
- Designed critical functional block of high voltage DC-DC converter performing Monte-Carlo and worst-case analysis for electric vehicle application
- Implementing VAVE of $500K for low-voltage DC-DC converters preferred for automotive applications
- Benchmarked competitor products, prepared a comparative study of architectures and trained the leadership
- Collaborated with global stakeholders for deep technical reviews and engaged with cross-functional teams like plant, quality, and SCM for improved process
- Performed thermal endurance and EMI/EMC test to validate phase reduction of a multiphase interleaved DC-DC converter with a savings of $5 in material BOM
- Led a team to conduct a root cause analysis of low voltage DC-DC converters and debugged the root cause within 3 days
- Prepared design documents using MATHCAD, designed magnetics, and interleaved converter to achieve a robust design with a targeted BOM cost
- Designed 4 layer PCBs with optimum glass transition temperature and copper thickness. Selection of surface finish led to $30K savings
- Led DFMEA, conducted component risk assessment for each design change, and prepared load rate analysis of electronic components
- Performed simulation profiling pulse 1,2a,2b,3a,3b and unsuppressed load dump as per ISO 7637-2 and ISO16750-2 which resulted in 20% reduction in DV testing time
- Completed 2D EMI/EMC simulation to gain customer confidence.
