Designing and developing electronic systems for a greater tomorrow by smartly utilizing the present technology to address future challenges.
My research interests include Power Electronics, Electromagnetics, Transient Surge Protection and Power Quality, Frequency Domain Circuit Modelling, Transformer Theory & Design, High Frequency Magnetics, Supercapacitor Applications for Sustainability, EVSE/EV Charging Efficiency and OCPP, and Physics.Following are some of my previous experiences in Research and Development:• Development of high-performance surge protectors (research collaboration with Magnetics® Inc. USA) using the latest commercial magnetic materials (Kool Mµ, High-Flux, X-Flux, Edge powder cores and Soft-Ferrites) manufactured by Magnetics Inc. • Permeance based theoretical modelling of surge protector circuits and high-voltage testing using standard lightning surge simulators (LSS-6230 and LSS-F03).• Research collaboration with Thor Technologies, Australia – surge endurance evaluation of commercial surge protectors according to Underwriters’ Laboratory test procedures. • Electromagnetic transient analysis and frequency domain circuit modelling.• Designing of data acquisition systems and computer interfacing techniques based on MATLAB.• Supercapacitor applications of power electronic circuits.• Transformer design using powdered-iron magnetic materials and air-gapped ferrites.• Feasibility Study of Green Hydrogen: NZ Scenario.• EVSE and EV Charging Efficiency and OCPP Compliance Testing: efficiency evaluation of fast DC chargers (Phihong-60, Phihong-30, Tritium-50, Delta-25) and level-2 AC home chargers (Siemens-7.4, Etrel-22, Evnex-7.4, ABB-7.4).• Study of EV charging internal efficiencies: testing of Tesla-3, BMW-i3, Hyundai-Ioniq EV and Nissan-Leaf.• Failure modes determination of power semiconductor devices: Si, SiC and GaN MOSFETs and HEMTs testing.
