Title:
ELECTROMAGNETIC INDUCTION-TYPE POWER GENERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/095555
Kind Code:
A1
Abstract:
[Problem] To provide an electromagnetic induction-type power generation device that can generate a desired amount of power even if the current flowing through a transmission line is small, and that, to the greatest extent possible, does not generate excess power when the current is large. [Solution] An electromagnetic induction-type power generation device 1 comprises: a current transformer 10 attached to a transmission line 2; a rectifier circuit 20 that rectifies an alternating current voltage outputted from the current transformer 10; and a regulator circuit 30 that regulates a direct current voltage outputted from the rectifier circuit so as to be at a certain voltage level. The current transformer 10 has a magnetic core 11 that is attached to the transmission line 2 serving as a primary winding wire, and a secondary winding wire 12 that is magnetically coupled to the transmission line 2 via the magnetic core 11. The magnetic core 11 is configured such that magnetic saturation begins when the current flowing through the transmission line 2 is near the minimum value of the fluctuation range of the current.
