  • Designed and developed a cutting-edge liquid-cooled inverter tailored for electric vehicles. The primary challenge was to create a system that accommodates heat dissipation, and electrical compatibility in a constrained space. o The new liquid-cooled inverters have a 15% lower weight, and 30% lower volume, and could dissipate up to 4 times the heat load compared to existing air-cooled inverters. o After successful field trials, the new inverter is installed in 800 electric buses, to drive a 120kW motor, and a few other inverters are installed in electric Mining trucks and Garbage trucks for field trails during my tenure at the firm. o Apart from electric vehicles, I developed liquid cooling magnetics including inverters, inductors, and transformers which are installed in 1600 WAG-7 and 75 Train-18 (under progress) locomotives. • I extensively utilized advanced analysis software such as Ansys Workbench, Femm, Abaqus, and MATLAB to facilitate a continuous drive for design enhancements. The complexity of this endeavor lay in identifying potential improvements within the models and striving to achieve efficient solutions. Notable design enhancements include: o Replacing costly stainless-steel clamps in inductors and transformers with more economical aluminum extruded clamps led to significant direct cost savings of approximately $250,000 in capital expenses and a notable 14% reduction in production time. o I utilized CFD analysis modules to optimize thermal design, efficiently extracting heat load under varying airflow or liquid flow resulting in increased operating current density from 2 A/mm2 to 15A/mm2. o Strengthened enclosure designs to withstand external vibrations up to 5g shock in locomotives and 30g shock in electric vehicles. o enhanced the enclosure designs for the inverter by introducing a casting model, improving the time for throughput by 26% and reducing the production costs by 18%.
