Mutual inductance energy-taking power supply control method and mutual inductance energy-taking power supply device

The invention relates to a mutual inductance energy-taking power supply control method and a mutual inductance energy-taking power supply device. The mutual-inductance energy-taking power supply control method specifically comprises the steps that an adjusting coil matched with an energy-taking coil is arranged in a mutual-inductance energy-taking power supply device, and the following control strategy is implemented according to the current magnitude of a power transmission conductor; the adjusting coil and the energy taking coil take energy and supply power together to improve the power supply output power; and when the current on the transmission conductor is greater than the required current, reverse current is provided for the adjusting coil to generate a reverse magnetic field, so that the magnetic field intensity generated by the magnetic core is weakened. In order to solve the problems that an existing mutual-inductance energy-taking power supply device is not adjustable in energy taking and is limite
