Abstract

The present invention relates to a non-contact power supply method for electric equipment. Said method includes the following measures: placing electric energy conversion circuit capable of converting commercial power or direct current into high-frequency alternating current at power supply side, placing high-frequency output coil in output loop of electric energy conversion circuit on a high-frequency magnetic core; placing power supply conversion circuit at electric equipment side, and placing high-frequency input coil in input loop of electric energy conversion circuit on another high-frequency magnetic core; combining the described two high-frequency magnetic cores, and utilizing high-frequency electromagnetic coupling mode to make the high-frequency electric energy produced by power supply conversion circuit positioned at power supply side be converted into commercial power or direct current required for electric equipment.

Description

technical field

[0001] The invention relates to electrical power supply and power conversion technology, in particular to a non-contact power supply method and a separate power conversion device for electrical equipment. Background technique

[0002] Generally, electrical appliances obtain electrical energy from the power supply through direct contact between electrical conductors, and various plugs and sockets are used to connect electrical appliances to the power supply; and electrical appliances with different voltages need power supplies of different specifications. Converter to get the power of the required specification. For example, electric shavers, mobile phones, etc. have different working voltage and current specifications, and generally require a dedicated power supply. At present, the mains can only provide alternating current with a fixed voltage, and cannot directly provide the low voltage required by electric shavers, mobile phones, etc. Direct current, trav...
