Title Switch-Mode Continuously Variable Transmission

Abstract
A primary challenge of a flywheel hybrid system is coupling a high speed flywheel to a vehicle's drive train. A unique way of accomplishing this task is using a switch-mode continuously variable transmission (CVT), which is the mechanical analog of a DC-DC power electronics converter. This project conducted a detailed modeling and analysis of the major components of a full size passenger vehicle switch-mode CVT. This model was scaled down to allow for the design and manufacturing of a benchtop prototype. Experimental data taken from the prototype was used to verify proof of concept and quantify the nature and magnitude of system losses. The analysis concluded that the system is feasible but future research is required in the areas of design and manufacturability.
