Title:
ELECTRIC POWER GENERATOR AND ELECTRIC POWER GENERATING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2012/001956
Kind Code:
A1
Abstract:
An electric power generator device is equipped with: an electric power generating part (101) that outputs DC energy; an oscillator (103) that converts the DC energy into an RF energy with a frequency (f0); a first antenna (107) that transmits the RF energy; a second antenna that receives at least part of the RF energy transmitted by the first antenna (107) by resonant magnetic coupling; and an output converter (120) that converts the RF energy obtained from the second antenna (109) to a lower frequency AC energy. When the step-up ratio of the oscillator (103) is regarded as Voc, the step-up ratio of the output converter (120) is regarded as Vtr, the inductance of a first inductor (107a) of the first antenna (107) is regarded as L1, the inductance of a second inductor (109a) of the second antenna (109) is regarded as L2, and the coupling coefficient between the first antenna (107) and the second antenna (109) is regarded as k, (L2/L1) ≥ (k/(Voc × Vtr))2 is satisfied.
