POWER RECEIVING DEVICE FOR OPTICAL POWER FEED SYSTEM, AND OPTICAL POWER FEED SYSTEM

摘要

A power receiving device 310A of an optical-fiber power feed system 1C includes a plurality of photoelectric conversion elements 311a, 311b, 311c that convert power feed light 112W into electrical power. Furthermore, the power receiving device comprises a spectroscope 312: that receives input of the power feed light and performs wavelength division of the power feed light to form power feed light 112a, 112b, 112c of a plurality of wavelength bands; and that outputs the power feed light 112a, 112b, 112c in a distributed manner to the plurality of photoelectric conversion elements. Each of the plurality of photoelectric conversion elements has a conversion wavelength region corresponding to the input power feed light and converts the input power feed light into electrical power.
