Title Design of inductive wireless power transmission system
Abstract
Inductive wireless power transmission has good safety,versatility, flexibility,long service life,non-contact,wear-free, etc.And it is a new type of power supply, wireless power supply is to use electromagnetic fields to transmit energy from one end to the other end of the technology.
In this paper,according to the principle of Faraday electromagnetic induction, for design of wireless power transmission scheme,power transmission by wireless means for the load end;Use Multisim simulation software for the design of circuit simulation,And select the corresponding components for that the hardware circuit is built to verify the simulation results.The hardware circuit is the energy transmitter designed to produce a high frequency PWM pulse width modulated square wave,After the power amplifier, the MOS switch tube is controlled to make the LC resonant circuit,Energy receiving end rectifier, filter through the integrated regulator chip voltage regulator,realization of power supply to the load.
The wireless energy transmission of experimental platform has been set up,light the small light bulb outside 30mm,and analyzes the factors that affect the transmission rate,gives the Suggestions to improve transmission efficiency.
Keywords Inductive wireless power transmission High frequency inverter Loosely coupled transformer Multisim simulation
