Mobile phone desktop wireless group-charging system supporting multiple protocols

Abstract

The invention discloses a mobile phone desktop wireless group-charging system supporting multiple protocols. The system comprises a network-side converter integrated with a desktop, a bus power supply module, a desktop guide rail type DC bus, a wireless power emission module, an emission coil and a power receiving load, wherein the network-side converter is used for converting power-frequency single-phase alternating current to stable high-voltage direct current and outputting the stable high-voltage direct current to the bus power supply module, the bus power supply module is used for converting the high-voltage direct current to low-voltage direct current and transmitting the low-voltage direct current to the desktop guide rail type DC bus, the wireless power emission module is used for fetching power from the desktop guide rail type DC bus and outputting the obtained low-voltage direct current to the emission coil, and the energy generated by emission coil passes through a non-metal desktop through space magnetic energy and is transmitted to the power receiving load with a receiving coil. Through the above mode, the system can support distributed multi-point wireless charging and support various wireless electric energy transmission protocols, and can be used for recognizing the power receiving load, metering and charging.

Description

technical field [0001] The invention relates to the technical field of power electronic conversion, in particular to a mobile phone desktop wireless group charging system and system supporting multiple protocols. Background technique [0002] At present, the personal ownership of mobile electronic devices such as mobile phones and portable computers is increasing year by year, and the charging problem has gradually become a problem for device owners. Because the construction of infrastructure in public places will first consider cost and safety issues, it is rare to provide charging for portable devices. Therefore, at present, charging or free charging services are mainly provided for portable electronic device owners in the form of centralized counters in public places, and portable electronic device owners need to wait nearby for charging to complete. Portable rechargeable batteries (power banks) can also complete the charging of portable electronic devices, but their limi...

AI Technical Summary

Problems solved by technology

Portable rechargeable batteries (power banks) can also complete the charging of portable electronic devices, but their limitations are: 1. Limited capacity; 2. Heavy weight; 3. Cannot charge multiple devices at the same time; 4. Carrying is limited by traffic modes

[0003] At present, the existing wireless chargers on the market can only realize 1-to-1 charging, and the distance of wireless charging is only millimeter level, and the transmitting end of wireless energy also needs to be connected to the DC or AC input with a wire, which cannot be very close to the desktop in terms of space. good fusion

At the same time, the current charging method for charging in public places is still limited to the coin-operated method. For the operator, additional human resources are required to manage the charging
