Abstract
The invention relates to a non-contact type portable power source power supply system, belongs to the technical field of wireless charging, and aims to solve the problems that existing wireless chargers are short in transmission distance, and receiving ends must contact with bases. The non-contact type portable power source power supply system comprises a power amplifier, a transmission coil device and a receiving coil device. The non-contact type portable power source power supply system adopting the magnetic resonance technology has the advantages that the system is long in transmission distance, capable of not contacting with the base, high in universality and portability, and capable of wirelessly charging USB power supply equipment.
Description
Art
The present invention relates to a kind of based on E class power amplifier, utilize magnetic resonance principle electric energy transmitting, can be the portable power source that the electronic product of Universal USB interface carries out efficient wireless charging.
Background technology
Existing wireless charger uses electromagnetic induction principle electric energy transmitting, efficiency is too low, use common power amplifier in circuit, it is large that power amplifier turns on and off loss. and in addition, electronic equipment can only be placed on appointed area charging by existing product, and this electronic equipment is generally mobile phone, do not comprise other electronic products, limitation is excessive, and the transmission standard of support is only QI, charging distance is also generally, within 15mm, do not have practicality in addition.
Summary of the invention
In order to overcome existing commercially this series products wireless charging apart from short, the problem that energy conversion efficiency is low, the present invention adopts E class power amplifier to drive transmitting coil, improves transmitting power, increases transmitting range, and utilize magnetic resonance principle to transmit.
The technical solution adopted for the present invention to solve the technical problems is: transmitter module by direct current energy signal through the process of E power-like amplifier, become and exchange vibration electric power signal, again the interchange handled well vibration electric power signal is input on transmitting coil and transfers transferable energy signals to, and this energy signals is launched, achieve the process being become magnetic energy by electric energy conversion.Wireless transport module utilizes magnetic resonance delivery of electrical energy principle, and energy signals is communicated to receiving terminal coil accurately, achieves the process of magnetic energy wireless transmission.Receiver module receives the energy signals transmitted by receiving coil, and this energy signals is treated to AC energy signal, then after over commutation, filtering, realizes alternating current transfer galvanic object to, thus achieves the process being converted into electric energy from magnetic energy.
The invention has the beneficial effects as follows, achieve the high power transmission of small-power power, increase wireless power transmission distance, overcome spatial limitation; Increase energy conversion efficiency, improve the speed of charging; Can charge by one-to-many simultaneously, save the charging interval; For the electronic equipment of in non-built coil charges, reduce use threshold.
Fig. 1 is system architecture diagram of the present invention.
