Abstract :
The article deals with the common problem of wireless energy transfer due to transmission coils misalignment, which creates substantial drift from the resonant frequency, and instability and low efficiency as a result. Research and tests of wireless energy transmission system prototype with full-scale transmission coils using the principle described assure that the method of adjusting the resonant frequency by using multi-capacitors circuit controlled allows to stabilize and fine-tune resonance frequency.
