中文摘要
直流-交流(DC-AC)變換電路,又稱為逆變器(inverter),能夠將直流電能轉換為交流電能。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,負載按換流或者外接電路強制換流,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行電能儲存,電源電壓脈動以及電源阻抗小,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能,電源電流脈動小,電源阻抗大,呈現(xiàn)電流源特性。按電路結構可分為橋式逆變器,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。按開關器件工作狀態(tài)可分為硬開關和軟開關電壓源逆變器。本畢業(yè)論文主要對電路結構及輸出相數(shù)進行逆變器的分析說明。
逆變器已經在工業(yè)、交通、能源、航空航天等領域得到廣泛應用,例如變頻調速裝置、電解電鍍電源、感應加熱電源、UPS、焊接電源等。

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. According to the circuit structure can be divided into bridge type inverter, the bridge type inverter and combined-type inverter circuits, etc. Few can be divided according to the output phase single-phase inverter, three-phase inverter and multiphase inverter. Press switch devices working state can be divided into hard switching and soft switching voltage source inverter.
