Technical Field
[0001] The utility model relates to the technical field of power converters, in particular to an intelligent power converter. Background Art
[0002] A power converter is an electrical device used to convert one form of power to another to meet the power needs of different devices or systems. It usually includes functions such as voltage conversion, current conversion, frequency conversion, and phase conversion. Power converters are widely used in homes, offices, and industrial environments to adapt to power standards in different countries or regions, or to provide appropriate voltage and current for specific devices.
[0003] The design of power converters needs to consider factors such as safety, efficiency, reliability, and electromagnetic compatibility. High-quality power converters can improve the performance and life of equipment, reduce energy consumption, and protect users from electrical faults and interference. Selecting the right power converter is essential to ensure the safe and efficient operation of electrical systems.
[0004] For the power converter, its main function is to match and convert different connectors and power. However, in actual applications, the power converter only plays a switching role and cannot provide prompts based on the charging status of the connected electrical appliances. Even after the electrical appliances are fully charged, they will continue to charge on the power converter, which will cause damage to the power converter and even the entire appliance.
[0005] Therefore, a smart power converter is proposed to solve or alleviate the above problems. Utility Model Content
[0006] The utility model aims to solve the shortcomings of the prior art and proposes an intelligent power converter.
[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0008] An intelligent power converter includes a shell, on which a double-core part, a triple-core part, and a USB wire part are arranged, and the double-core part, the triple-core part, and the USB wire part are all arranged with a charging circuit. A through hole is opened on the shell, and a prompt circuit coupled to the charging circuit is arranged in the shell. The prompt circuit can emit light of various colors according to the charging status of the charged appliance, and several of the charging circuits are coupled with connecting wires through power switches.
[0009] Preferably, one end of the connecting wire away from the charging circuit is coupled with a USB connector.
[0010] Preferably, a transparent cover made of transparent material is fixedly connected in the through hole.
[0011] Preferably, the prompt circuit comprises a red light emitting diode and a green light emitting diode, and the red light emitting diode and the green light emitting diode are connected in opposite directions.
[0012] Preferably, the charging circuit includes a photocoupler, a high-speed diode, an NPN-type transistor, a transistor switch, a rectifier diode, a transformer coil, and a voltage comparator.
[0013] The utility model has the following beneficial effects:
[0014] The utility model realizes the on-off of the connection wire and the charging circuit in the double-core part, the three-core part and the USB line part through the power switch. After the charging circuit in the double-core part, the three-core part and the USB line part is connected to the electrical appliance for charging, the prompt circuit can emit red light or green light according to the situation in the charging circuit. If red light is emitted, it means that the electrical appliance connected to the charging circuit in the double-core part, the three-core part and the USB line part still needs to be charged. If green light is emitted, it means that the electrical appliance connected to the charging circuit in the double-core part, the three-core part and the USB line part is in a fully charged state, and the plug of the electrical appliance can be unplugged from the double-core part, the three-core part and the USB line part at any time.
