【摘要】：電動汽車近些年來越來越受到大眾的青睞,它是以電能為動力的交通工具,因而作為給電池提供電能的充電樁是不可或缺的裝置,在充電過程中起著舉足輕重的作用。對充電樁進(jìn)行電磁兼容性測試,讓充電樁在復(fù)雜的電磁環(huán)境中能正常穩(wěn)定的工作,也是充電樁研究的一方面。一般對充電樁的電磁兼容測試分為三種:浪涌測試、靜電放電測試、電快速瞬變脈沖群測試,其中電快速瞬變脈沖測試(又稱EFT測試)是較為嚴(yán)格的一種。本課題主要研制了一種用于交流充電樁EFT測試的高壓脈沖源,它產(chǎn)生的EFT脈沖信號具有幅值高、前沿陡、脈沖窄等特點(diǎn),符合充電樁EFT測試的標(biāo)準(zhǔn)。為了降低脈沖源的體積與質(zhì)量,提高使用的效率,本文采用的方法是用高壓開關(guān)電源代替?zhèn)鹘y(tǒng)的線性電源。其次,為了減小脈沖源的電磁輻射,采用濾波器來抑制干擾信號的傳播,使用光耦隔離電路來提高脈沖源的電磁兼容性。全文分為以下幾個部分進(jìn)行分析:首先介紹了國內(nèi)外脈沖功率技術(shù)的研究現(xiàn)狀,并且搭建交流充電樁EFT測試模型;其次分析了充電樁電磁干擾模型與耦合路徑,再重點(diǎn)分析了以氫閘流管作為主開關(guān)器件的脈沖源的軟硬件設(shè)計(jì),包括主體電路的建模與MATLAB仿真、脈沖源發(fā)生器的高壓直流部分、全橋驅(qū)動電路與脈沖變壓器的設(shè)計(jì),基于TMS320F2812為控制器的軟件設(shè)計(jì)、基于VB6.0軟件的上位機(jī)的設(shè)計(jì)等;最后對設(shè)計(jì)的高壓脈沖源進(jìn)行了系統(tǒng)的試驗(yàn)分析。
[Abstract]:Electric vehicle (EV) is more and more popular in recent years. It is a vehicle powered by electric energy, so as an indispensable device to provide electric energy to the battery, it plays an important role in the charging process. It is also one of the aspects of the research of charging pile to test the EMC of charging pile so that the charging pile can work stably in complex electromagnetic environment. Generally, there are three kinds of EMC test for charging pile: surge test, electrostatic discharge test, electric fast transient pulse group test, among which the electric fast transient pulse test (EFT test) is a more strict one. In this paper, a high voltage pulse source for EFT test of AC charging pile is developed. The EFT pulse signal produced by the source has the characteristics of high amplitude, steep front edge and narrow pulse, which accords with the standard of EFT test of charging pile. In order to reduce the volume and quality of the pulse source and improve the efficiency of use, the method used in this paper is to replace the traditional linear power supply with the high-voltage switching power supply. Secondly, in order to reduce the electromagnetic radiation of the pulse source, the filter is used to suppress the propagation of the interference signal, and the optocoupler isolation circuit is used to improve the electromagnetic compatibility of the pulse source. The paper is divided into the following parts: firstly, the research status of pulse power technology at home and abroad is introduced, and the EFT test model of AC charging pile is built. Secondly, the electromagnetic interference model and coupling path of charging pile are analyzed. The hardware and software design of the pulse source with hydrogen thyratron as the main switch device is analyzed, including the modeling and MATLAB simulation of the main circuit, the high voltage DC part of the pulse source generator, the design of the full-bridge drive circuit and the pulse transformer. The software design based on TMS320F2812 controller and the host computer based on VB6.0 software are designed. Finally, the design of high voltage pulse source is systematically analyzed.
