中文摘要
直流-交流(DC-AC)变换电路，又称为逆变器(inverter),能够将直流电能转换为交流电能。逆变电路可做多种种类，按功率器件可分为半控器件逆变电路和全控器件逆变电路。前者采用晶闸管器件，负载按换流或者外接电路强制换流，正逐渐被采用GTO、IGBT等器件的全控器件逆变器所代替。按输出波形，可分为方波逆变器、正弦波逆变器等。按直流电源形式可分为电压源逆变器(Voltage Source Inverter,VSI)和电流源逆变器(Current Source Inverter)。前者采用电容元件为直流源进行电能储存，电源电压脉动以及电源阻抗小，特性类似电压源，而后者采用电感元件为直流源提供磁场储能，电源电流脉动小，电源阻抗大，呈现电流源特性。按电路结构可分为桥式逆变器，非桥式逆变器和组合式逆变电路等。按输出相数可分为单相逆变器、三相逆变器和多相逆变器。按开关器件工作状态可分为硬开关和软开关电压源逆变器。本毕业论文主要对电路结构及输出相数进行逆变器的分析说明。

ABSTRACT
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.
