POWER-SUPPLYING AND PICK-UP SYSTEM WITH STABLE TRANSMISSION-EFFICIENCY IN CONDITION OF VARIANCE OF RESONANT FREQUENCY

摘要

PURPOSE: A power collecting system is provided to maintain the power transmission efficiency between a power collecting device and a power supply device in the change of power or current. CONSTITUTION: A power collecting system supplies power to a mobile body with a self-induction method. The power collecting system includes a power supply core(211) and a power supply coil(212). The power supply core includes a magnetic pole for forming a magnetic field in a specific direction. A power supply coil supplies current by arranging neighbor electrodes.
