直流-交流(DC-AC)變換電路，又稱為逆變器(inverter),能夠?qū)⒅绷麟娔苻D(zhuǎn)換為交流電能。逆變電路可做多種種類，按功率器件可分為半控器件逆變電路和全控器件逆變電路。前者采用晶閘管器件，負(fù)載按換流或者外接電路強(qiáng)制換流，正逐漸被采用GTO、IGBT等器件的全控器件逆變器所代替。按輸出波形，可分為方波逆變器、正弦波逆變器等。按直流電源形式可分為電壓源逆變器(Voltage Source Inverter,VSI)和電流源逆變器(Current Source Inverter)。前者采用電容元件為直流源進(jìn)行電能儲(chǔ)存，電源電壓脈動(dòng)以及電源阻抗小，特性類似電壓源，而后者采用電感元件為直流源提供磁場儲(chǔ)能，電源電流脈動(dòng)小，電源阻抗大，呈現(xiàn)電流源特性。按電路結(jié)構(gòu)可分為橋式逆變器，非橋式逆變器和組合式逆變電路等。按輸出相數(shù)可分為單相逆變器、三相逆變器和多相逆變器。按開關(guān)器件工作狀態(tài)可分為硬開關(guān)和軟開關(guān)電壓源逆變器。本畢業(yè)論文主要對(duì)電路結(jié)構(gòu)及輸出相數(shù)進(jìn)行逆變器的分析說明。
逆變器已經(jīng)在工業(yè)、交通、能源、航空航天等領(lǐng)域得到廣泛應(yīng)用，例如變頻調(diào)速裝置、電解電鍍電源、感應(yīng)加熱電源、UPS、焊接電源等。
MATLAB是一種科學(xué)計(jì)算軟件，它是一種以矩陣為基礎(chǔ)的交互式程序計(jì)算語言。SIMULINK是基于框圖的仿真平臺(tái)，它掛接在MATLAB環(huán)境上，以MATLAB的強(qiáng)大計(jì)算功能為基礎(chǔ)，以直觀的模塊框圖進(jìn)行仿真和計(jì)算。
本文主要以MATLAB/SIMULINK仿真軟件為基礎(chǔ)，完成了對(duì)單相橋式全控整流及有源逆變電路、三相半波整流及有源逆變電路、三相橋式整流及有源逆變電路、正弦波脈寬調(diào)制逆變器及滯環(huán)控制三相電流跟蹤型逆變器的仿真并且給出了仿真結(jié)果波形，同時(shí)根據(jù)仿真結(jié)果進(jìn)行了分析和計(jì)算。證實(shí)了該方法的簡便直觀、高效快捷和真實(shí)準(zhǔn)確性。

DC - exchange (DC - AC) transform circuit, also called inverter (inverter), able to DC for communication can convert electricity. Inverter circuits can do many kinds, press the power devices can be divided into half empty device inverter circuits and all control device inverter circuits. The former using thyristor devices, load flow changing or an external circuit by compulsory commutation, gradually by using GTO, IGBT inverter with all the control device is replaced. According to the output waveform, can be divided into square-wave inverter, sine-wave inversion, etc. According to the dc power forms can be divided into Voltage Source Inverter (Inverter, by VSI) returned and Source Current Inverter (Inverter) is returned. The former adopts capacitance components for dc source voltage ripple energy storage, and power impedance small, similar characteristics, and the latter voltage sources for dc sources using inductive components provide field energy, power current pulse small, power impedance is big, presents a current source characteristics.
