Abstract

　In order to reduce the weight of the onbord pickup coil for the wireless power transfer for railway vehicles, the core shape of the pickup coil was optimized by multiobjective optimization using a genetic algorithm with topology optimization. The optimaization results provide a guideline for core reduction.
