DEVICE FOR POWER SUPPLY TO LOAD AND SYSTEM CONNECTED TO IT Russian patent published in 2008 - IPC H01F38/14 

FIELD: electricity.

SUBSTANCE: device for power supply to load includes source of power (102), for instance, commutated electronic transformer or electronic ballast, which is equipped with input for connection of power supply from AC grid of industrial frequency, and facilities for conversion of industrial frequency to the higher one, for instance, 30-50 kHz, and output for supply of power with specified higher frequency. Socket (108) from two parts includes the first part (106) of core that includes the primary winding (104), which is connected to the output of power supply source and the second part (112) of core adjacent to it that includes the secondary winding (110) for supply of power to the load (114), at that parts of core are made of material with high specific resistance, for instance, ferrite, with specific resistance of at least 10⁴ Ohm*cm. Device may be used for supply of, for instance, halogen low voltage lamps or other types of light instruments in glow lamps, fluorescent lighting fixtures, or electric motors, computers, radio receivers, television receivers or other electronic devices, heating devices, etc.

EFFECT: provision of safe operation.
