método de controle de frequência ressonante, dispositivo transmissor de energia elétrica, dispositivo receptor de energia elétrica em sistema de transmissão de energia do tipo de acoplamento ressonante magnético. a presente inveção refere-se em um método de controle de frequência reessonante em um sistema da trasmissão de energia do tipo de acoplamento ressonante de campo magnético transmissor uma energia alétrica de uma bobina transmissora de energia para bobina receptora de energia usando ressonância de campo magnético, é realizado um ajuste de alta velocidade, preciso e em tempo real da frequência ressonante de uma bobina. a fase de uma tensão fornecida para uma bobina transmissora de energia e a fase de uma corrente que flui na bobina transmissora de energia tem uma bobina receptora de energia é variada de modo que a diferença de fase entre as mesmas se torne um valor alvo. a bobina transmissora de energia tem uma bobina de fornecimento de energia para a qual uma fonte de alimentação de corrente alternada é conectada e uma bobina ressonante transmissora de energia acoplada eletromagneticamente estreitamente com a bobina de fornecimento de energia, e a bobina receptora de energia ressonante e uma bobina ressonante receptor de energia. é realizado controle de modo que a diferença de fase entre a tensão da fonte de alimentação de corrente alternada e a corrente da bobina ressonante transmissora de energia se torne um valor alvo < 225 > , e a difeerença de fase entree a tensão da fonte de alimentação de corrente alternada e a corrente da bobina ressonante receptora de energia se torne um valor alvo (<255>-<sym>/2).resonant frequency control method, electric power transmitting device, electric power receiving device in magnetic resonant coupling type power transmission system. The present invention relates to a resonant frequency control method in a transmitting resonant magnetic field coupling type energy transmission system an electric energy from a transmitting coil to a receiving energy coil using magnetic field resonance, High-speed, accurate, real-time adjustment of the resonant frequency of a coil is performed. the phase of a voltage supplied to a power transmitting coil and the phase of a current flowing in the power transmitting coil has a power receiving coil is varied so that the phase difference between them becomes a target value. the power transmitting coil has a power supply coil to which an ac power supply is connected and a resonant power transmitting coil electromagnetically coupled closely with the power supply coil, and the resonant power receiving coil and a resonant coil receiving energy. control is performed so that the phase difference between the AC power supply voltage and the power transmitting resonant coil current becomes a target value <225>, and the phase difference between the power supply voltage alternating current and the current of the receiving energy resonant coil becomes a target value (<255> - <sym> / 2).
