ELECTROMAGNETIC-INDUCTIVE POWER SUPPLY APPARATUS

WIPO Patent Application WO/2018/070779

A1

Disclosed is an electromagnetic-inductive power supply apparatus which has a plurality of coils having different numbers of windings from each other wound around a current transformer core, and which, on the basis of a voltage induced at the current transformer, switches so that at least one of the coils is connected in series with a rectification unit, thereby enabling power within a predetermined range to be generated even in a state where a voltage deviating from a reference value is induced. The disclosed electromagnetic-inductive power supply apparatus comprises: a current transformer installed on a power line and having a plurality of unit coils for inducing a voltage; a sensing unit for detecting the voltage induced at the current transformer; a rectification unit for rectifying the voltage induced at the current transformer; and a switching unit for, on the basis of the voltage sensed at the sensing unit, switching so that at least one of the plurality of unit coils is connected with the rectification unit.
