Outline of Final Research Achievements

The purpose of this project is to establish the power management architecture for contactless power supply systems. Concretely, we achieved: (1)modeling of magnetic coupling part based on physics, (2)optimization method for maximizing the power delivery efficiency of DC-DC contactless power supply, (3)theoretical clarifications of power dissipation mechanism, and (4)establishment the power manage system design theory for contactless power supply. It becomes possible from the results of this project to design the contactless power supply with theoretical limitation of power delivery efficiency. The established theory was verified from the comparisons of experimental measurements, which showed the quantitative agreements.
