ELECTROMAGNETIC INDUCTION TYPE POWER SUPPLY DEVICE

Disclosed is an electromagnetic induction type power supply device, which generates necessary electric power through an electromagnetic induction method using a transformer from electric current flowing through a transmission line, can adjust an output thereof by detecting and feeding back the output, enables a transformer and a power converting unit to be simply added or removed as necessary even in a situation in which the current constantly flows, thereby increasing the availability thereof, and can supply electric power with stable and improved quality. The electromagnetic induction type power supply device includes: a transformer module including a plurality of transformers for outputting electric power by inducing, in an electromagnetic induction method, secondary current from primary current flowing through a transmission line; a power source module including a plurality of power converting units for converting the electric power outputted from the plurality of transformers to direct current power and outputting the converted power; and a power summing unit for summing the direct current power outputted from the plurality of transformers and providing the summed power to a load.
