Problems solved by technology

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, travel and work not only need

Example Embodiment

[0034] Embodiment 2 is a separate power conversion device applied to a power base.

[0035] Such as Figure 4 As shown, a power-side power converter is installed in the housing 30 of the power socket. The power-side power converter includes an electric energy conversion circuit 3 for converting mains power into high-frequency alternating current, and is connected in series with the high-frequency output of the electric energy conversion circuit 3. The output coil 4'in the loop is arranged on a high-frequency magnetic core 4. The electric energy conversion circuit 3 is connected in series with an electromagnetic radiation suppression switch 15 in the input circuit. The switch is open when the electrical appliance is not powered, with an output coil 4' The high-frequency magnetic core 4 is installed at the power supply port of the housing 30 of the power supply base, and a useful electrical appliance support base 16 is also provided at the power supply port of the housing 30 of the p...

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...
