【摘要】：隨著科學(xué)技術(shù)的發(fā)展，便攜式桌面電氣設(shè)備日益普及，其中大部分采用傳統(tǒng)的有線供電方式，但存在安全性低、可靠性差、攜帶不方便等缺點(diǎn)。因此，無線供電技術(shù)受到了廣泛的關(guān)注。 感應(yīng)耦合式電能傳輸技術(shù)(ICPT)是一種利用電磁感應(yīng)原理的無線電能傳輸技術(shù)。本文分別對單相ICPT和三相ICPT系統(tǒng)的逆變電路拓?fù)浜凸β恃a(bǔ)償拓?fù)溥M(jìn)行研究，并給出了單相ICPT系統(tǒng)的原副邊諧振參數(shù)的計算公式。 桌面電氣設(shè)備存在著使用位置不確定、多設(shè)備并行供電的問題。本文通過供電模式的合理選擇和負(fù)載識別技術(shù)使問題得以解決。首先選取了無線供電網(wǎng)技術(shù)作為無線供電平臺的供電模式，并對無線供電平臺的原副邊線圈結(jié)構(gòu)進(jìn)行了分析后選擇出合適的結(jié)構(gòu)。然后提出了負(fù)載識別方案，將無線供電平臺按區(qū)域劃分，通過射頻識別技術(shù)(RFID)確定負(fù)載所在的區(qū)域后循環(huán)導(dǎo)通該區(qū)域的原邊線圈，進(jìn)而判斷出離負(fù)載最近的一組線圈，并采用這組線圈為負(fù)載供電。由于采用的三相ICPT系統(tǒng)存在電壓拾取盲點(diǎn)，對相應(yīng)的抑制方法進(jìn)行了研究。本文完成了無線供電平臺的硬件電路設(shè)計，主要包括主電路拓?fù)洹?shù)選擇、負(fù)載識別電路以及副邊電能變換電路的設(shè)計。 采用有限元計算對無線供電平臺原邊線圈的磁場進(jìn)行了分析，驗(yàn)證了螺旋線圈優(yōu)化繞制方法的有效性。并根據(jù)無線供電平臺的設(shè)計參數(shù)，搭建了仿真模型和實(shí)驗(yàn)平臺，，實(shí)驗(yàn)結(jié)果符合理論分析并與仿真結(jié)果一致。最后對電壓拾取盲點(diǎn)抑制方法進(jìn)行了驗(yàn)證分析。
[Abstract]:With the development of science and technology, portable desktop electrical equipment is becoming more and more popular, most of which use traditional wired power supply, but there are some shortcomings such as low security, poor reliability, inconvenient carrying and so on. Therefore, wireless power supply technology has received extensive attention. Inductive coupled Power Transmission (ICPTT) is a radio energy transmission technology based on electromagnetic induction. In this paper, the inverter circuit topology and power compensation topology of single-phase ICPT and three-phase ICPT systems are studied, and the formulas for calculating the primary and secondary resonance parameters of single-phase ICPT systems are given. Desktop electrical equipment has the problem of uncertain use position and parallel power supply of multi-equipment. The problem can be solved by reasonable selection of power supply mode and identification of load. Firstly, the wireless power supply technology is selected as the power supply mode of the wireless power supply platform, and the structure of the primary and secondary coils of the wireless power supply platform is analyzed and the appropriate structure is selected. Then a load identification scheme is put forward. The wireless power supply platform is divided according to the region, and the area in which the load is located is determined by radio frequency identification (RFID) technology. The primary coil of the region is turned on after circulation, and the group of coils closest to the load is judged. This group of coils are used to power the load. Due to the blind spot of voltage pickup in the three-phase ICPT system, the corresponding suppression methods are studied. In this paper, the hardware circuit design of wireless power supply platform is completed, including the main circuit topology, parameter selection, load identification circuit and secondary side power conversion circuit design. The magnetic field of the primary coil of the wireless power supply platform is analyzed by finite element method, which verifies the effectiveness of the optimal winding method of the helical coil. According to the design parameters of the wireless power supply platform, the simulation model and the experimental platform are built. The experimental results agree with the theoretical analysis and the simulation results. Finally, the blind spot suppression method of voltage pickup is verified and analyzed.
