【摘要】：感應(yīng)耦合電能傳輸技術(shù)的原理是將交流市電通過一系列的整流與逆變轉(zhuǎn)換后從發(fā)射端通過磁場耦合的方式傳送到接收端。非接觸供電技術(shù)的發(fā)展迅速,特別是進(jìn)入21世紀(jì)后,研究人員對ICPT技術(shù)的研究主要是針對恒定負(fù)載穩(wěn)壓供電方面。但隨著人們需求的增加,動(dòng)態(tài)多負(fù)載供電也隨之出現(xiàn)。動(dòng)態(tài)多負(fù)載供電主要是負(fù)載在發(fā)生擾動(dòng)時(shí)會(huì)加大對輸出電壓的影響,使輸出電壓不能穩(wěn)定在所需要的范圍內(nèi),而且,負(fù)載的變動(dòng)會(huì)引起副邊回路輸出電壓的跳變繼而引發(fā)原邊逆變器回路大的環(huán)流,造成系統(tǒng)的傳輸功率降低,嚴(yán)重時(shí)就會(huì)燒壞器件甚至引發(fā)火災(zāi)。對此,本文驗(yàn)證了一種新的控制策略:負(fù)載的接入或者移除,會(huì)使負(fù)載參數(shù)發(fā)生擾動(dòng),反射到原邊的阻抗會(huì)發(fā)生改變,進(jìn)而原邊的電壓和電流就會(huì)變化,通過采集發(fā)射端的電壓和電流來間接控制負(fù)載電壓的穩(wěn)定。本課題先從研究無線電能傳輸技術(shù)的背景出發(fā),講述了無線充電系統(tǒng)在國內(nèi)外的研究現(xiàn)狀和發(fā)展趨勢,確定了研究本課題的目的、意義和主要內(nèi)容。其次,分析了現(xiàn)有的幾種無線供電的穩(wěn)壓控制策略的優(yōu)點(diǎn)和缺點(diǎn)。之后,介紹了 ICPT系統(tǒng)的傳輸拓?fù)浣Y(jié)構(gòu)和工作過程,并在此基礎(chǔ)上介紹了基于反射阻抗控制策略的基本原理和控制方法。然后通過Matlab/Simulink仿真平臺(tái)搭建了基于互感理論的仿真模型,仿真分別輸出了系統(tǒng)在恒定負(fù)載下、輕載切換到重載以及重載切換到輕載三種情況下的負(fù)載電壓,驗(yàn)證了反射阻抗控制策略的可行性。最后,設(shè)計(jì)了系統(tǒng)的硬件電路,并編寫了軟件控制部分,搭建了系統(tǒng)的硬件實(shí)驗(yàn)平臺(tái),驗(yàn)證了這種穩(wěn)壓控制策略的有效性。通過仿真波形和實(shí)驗(yàn)結(jié)果可知,基于反射阻抗的穩(wěn)壓控制策略,可在不增加元器件的基礎(chǔ)上通過軟件控制就可達(dá)到負(fù)載的穩(wěn)壓效果。
[Abstract]:The principle of inductively coupled power transmission technology is to transfer AC power through a series of rectifiers and inverters from the transmitter to the receiving end through magnetic field coupling. The technology of non-contact power supply is developing rapidly, especially after entering the 21st century. The researchers' research on ICPT technology is mainly focused on the steady load power supply. But as the demand increases, Dynamic multi-load power supply also appears. Dynamic multi-load power supply is that the load will increase the impact on the output voltage in the event of disturbance, so that the output voltage can not be stabilized within the required range, and, The change of load will lead to the jump of output voltage of auxiliary circuit, which will lead to the large circulation of the original side inverter circuit, which will reduce the transmission power of the system, and will burn out the device or even cause fire when it is serious. This paper verifies a new control strategy: when load is accessed or removed, the load parameters will be disturbed, the impedance reflected to the original edge will change, and the voltage and current of the original edge will change. The stability of load voltage is controlled indirectly by collecting the voltage and current of the transmitter. Firstly, from the background of the research on radio energy transmission technology, the research status and development trend of wireless charging system at home and abroad are described. The purpose, significance and main contents of the research are determined. Secondly, the advantages and disadvantages of several existing voltage stabilizing control strategies for wireless power supply are analyzed. After that, the transmission topology and working process of ICPT system are introduced. Then the simulation model based on mutual inductance theory is set up through Matlab/Simulink simulation platform, and the simulation outputs the system under constant load. The feasibility of reflective impedance control strategy is verified by switching from light load to heavy load and heavy load to light load. Finally, the hardware circuit of the system is designed and the software control part is written. The hardware experiment platform of the system is built to verify the effectiveness of the voltage stabilizing control strategy. The simulation waveform and experimental results show that the voltage stabilization control strategy based on reflective impedance is effective. The load stabilization effect can be achieved by software control without adding components.
