Power generation system and power generating unit

摘要

The power generation system includes first and second power generating units, each of which converts DC energy into RF energy and transmits the power wirelessly, a combining section, which combines the respective outputs of the power generating units together, and an oscillation phase control section, which reduces the phase difference between the RF energies supplied from the two power generating units and. The oscillation phase control section controls a phase difference between the RF energies supplied from the oscillators and belonging to the first and second power generating units and, respectively, so that first and second RF energies supplied from the first and second power generating units and are in phase with each other when combined together by the combining section.

1. A power generation system comprising:
first and second power generating units, each of which includes: a power generating device that outputs DC energy; an oscillator that converts the DC energy supplied from the power generating device into RF energy having a frequency f0 and that outputs the RF energy; a power transmitting antenna that transmits the RF energy supplied from the oscillator; and a power receiving antenna that receives at least a part of the RF energy that has been transmitted by the power transmitting antenna, the resonant frequencies of the power transmitting and power receiving antennas being set to be equal to the frequency f0, the power generating unit outputting the RF energy that has been received by the power receiving antenna; a combining section that receives and combines the RF energies supplied from those power generating units and outputs combined RF energy; and an oscillation phase control section that controls the oscillators belonging to the first and second power generating units to control a phase difference between the RF energies supplied from the oscillators belonging to the first and second power generating units, respectively, so that first and second RF energies supplied from the first and second power generating units are in phase with each other prior to being combined together by the combining section.
