Multi-capacitor circuit application for the wireless energy transmission system coils resonant frequency adjustment

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.
