Therefore, as the primary side current increases, the output power of the current transformer increases rapidly from zero, and high power output will inevitably result in higher voltage and higher heat consumption, which will cause serious heating of the load components and may endanger the safety of the load equipment; And when the output power or voltage of the transformer exceeds the bearing capacity of the load, it will inevitably damage the load equipment.
[0003] Therefore, the traditional use of current transformers as energy harvesting devices for levitation power collection can only provide power within a small current range on the primary side of the current transformer; Damage to energy harvesting device

Description
technical field [0001] The invention relates to the application field of electromagnetic induction, in particular to a suspension power-taking device. Background technique [0002] When the traditional current transformer is used as an energy harvesting device for levitation power collection, there is a maximum output power of the current transformer, which is proportional to the square of the primary side current of the current transformer. Therefore, as the primary side current increases, the output power of the current transformer increases rapidly from zero, and high power output will inevitably result in higher voltage and higher heat consumption, which will cause serious heating of the load components and may endanger the safety of the load equipment; And when the output power or voltage of the transformer exceeds the bearing capacity of the load, it will inevitably damage the load equipment. [0003] Therefore, the traditional use of current transformers as energy ha...
