Electromagnetic induction power generator

An electromagnetic induction power generator comprising:

• a magnetic core attachable to a power transmission/distribution line;
• a generating coil wound around the magnetic core;
• and
• a switching power supply circuit that converts AC power appearing at both ends of the generating coil into DC power,
• wherein the switching power supply circuit includes a control circuit that stops a switching operation based on a voltage level of the DC power, and
• wherein the control circuit is further configured to control the switching power supply circuit such that:
• the switching power supply circuit intermittently performs the switching operation in response to a voltage level of the DC power exceeding a first predetermined value to increase a reactive power;
• the switching power supply circuit that includes a voltage converting circuit controls the voltage converting circuit to convert the voltage level of the DC power and supply a resultant DC power to an IoT device;
• and
• the switching power supply circuit adjusts the reactive power such that a total of power loss of the voltage converting circuit and load power consumed by the IoT device is equal to an active power.
