外文翻译--光伏并网逆变器
中文1125字译文：光伏并网逆变器最近，人们越来越关注的替代能源，因为化石燃料和核电厂的环境影响及其稳定性（长尾和原田，1997年; Myrzlk，2001年）。
在各种替代能源中，太阳能发电尤为重视，除了因为它是一种清洁的，无限的能源，此外相当多的研究已经在这一领域取得了突出的成绩。
太阳能发电系统由太阳电池组件，充电电池，和一个逆变器。
现在只有逆变电流模式进入主流，原因是光伏逆变是正弦电流进入电网。
具体体现在单相并网光伏逆变器中，它具有普遍的拓扑结构，这是标准的全桥电压源逆变器（电平逆变器），它可以创建一个正弦电网电流（Kjaeret al., 2005; Kojabadi et al., 2006）。
这种拓扑结构有两个普遍的问题如下。
（ 1 ）电池是太阳能发电厂必不可少的储存电能设备。
但电池充电是一个短期和有污染的过程，并且有负面经济的效率。
然而，逆变器可以不使用电池可以解决这些问题。
在这个过程中，接口电路为逆变环节的直流电（ DC ）输出的太阳能电池阵列的交流电源系统。
如果输出电压的电流源逆变低于电力系统电压和在发生短路负荷或逆变器故障，它没有电流短路（Myrzlk，2001年）。
（ 2 ）在一般的微处理器作为控制器，以实现良好的特点时，太阳能发电系统与电流源逆变器的设计。
是在控制器以较少的价值，有高质量电感和电波的输出电流的高开关频率变频器所需要的，但是，受限制的是开关损耗和处理器的采样频率。

它由五个开关，一个电感器， LC滤波器，输出端口。
逆变器工作在这两个开关模式。
质量保证开关只执行斩波行动，而第一季度，第四季度交换机确定方向的输出电压根据极性的电力系统。
因此，与一般全桥PWM 逆变器执行完整的一块，该系统减少了开关损耗。
图.2显示波形的传统电流源逆变器。
它代表了波形的输出电压和电流，该电流通过电感，输入信号，每个开关。

微型并网逆变器
微型并网逆变器（micro-inverter）一、 微型并网逆变器所谓的“微型并网逆变器”，就是将并网逆变器直接与单个光伏组件集成，为每个光伏组件单独配备一个具备交直流转换功能和最大功率点跟踪功能的逆变器模块，将光伏组件发出的电能直接转换成交流电能供交流负载使用或传输到电网，通俗地讲，就是通过微型并网逆变器把光伏电池直流组件（DC-module）转变成了交流（AC—module）电池组件。
这样做的话，以后的光伏市场上不需要卖太阳能电池板和逆变器了，直接卖交流电池组件，回家后往插座上一插，就可以看电视了。
目前市场上见到的微型逆变器如下图所示：二、 适用场合和特点这类设备的适用场合和特点：（1）太阳能电池板生产的初期，电池板的参数严重不一致性时，光伏电池板的串并联后，损耗很大，利用这种微型并网逆变器，就能够化解这一问题，因为带微型并网逆变器的光伏组件输出的是与电网频率、电压幅值、相角一致交流量，不再是直流量（直流电压和直流电流）；电池板的参数不一致性只能导致各个交流组件之间输出电流（功率）的不同。
（2）可以把MPPT算法做到微型并网逆变器内，使每个交流（AC—module）电池组件输出最优，从而做到整个电站的最优。
（3）由于云朵、阴影和背阴遮挡单块光伏电池板时，仅影响单块交流（AC—module）电池组件输出，对这个电站输出影响不大，克服了传统电站中一块光伏电池直流组件受遮挡，影响一串或多串的问题。
（4）当交流（AC—module）电池组件中有一块损坏，不能良好工作时，只有本块会受到影响，其他光伏板（AC—module）都将在最佳工作状态运行，使得系统总体效率更高，发电量更大。
克服了传统电站中，若组串型并网逆变器或有一块光伏电池直流组件（DC-module）出现故障，则会引起几千瓦的电池板不能发挥作用。
同时，每个交流（AC—module）电池组件都是标准的，发生问题时，直接替换交流模块就可以。
（5）这类产品特别适合于MW级以下光伏电站，特别是BIPV或BAPV，在MW及以上电站设计中，若采用以MW为单位分层分布控制的话，问题应该不会太大。

光伏逆变器中英文对照资料外文翻译文献
外文翻译文献中英文对照资料外文翻译文献光伏逆变器的发展及优势结构与工作原理逆变器是一种由半导体器件组成的电力调整装置，主要用于把直流电力转换成交流电力。
一般由升压回路和逆变桥式回路构成。
升压回路把太阳电池的直流电压升压到逆变器输出控制所需的直流电压；逆变桥式回路则把升压后的直流电压等价地转换成常用频率的交流电压。
逆变器主要由晶体管等开关元件构成，通过有规则地让开关元件重复开-关（ON-OFF），使直流输入变成交流输出。
当然，这样单纯地由开和关回路产生的逆变器输出波形并不实用。
一般需要采用高频脉宽调制（SPWM），使靠近正弦波两端的电压宽度变狭，正弦波中央的电压宽度变宽，并在半周期内始终让开关元件按一定频率朝一方向动作，这样形成一个脉冲波列（拟正弦波）。
然后让脉冲波通过简单的滤波器形成正弦波。
逆变器不仅具有直交流变换功能，还具有最大限度地发挥太阳电池性能的功能和系统故障保护功能。
归纳起来有自动运行和停机功能、最大功率跟踪控制功能、防单独运行功能（并网系统用）、自动电压调整功能（并网系统用）、直流检测功能（并网系统用）、直流接地检测功能（并网系统用）。
这里简单介绍自动运行和停机功能及最大功率跟踪控制功能。
1、自动运行和停机功能早晨日出后，太阳辐射强度逐渐增强，太阳电池的输出也随之增大，当达到逆变器工作所需的输出功率后，逆变器即自动开始运行。
进入运行后，逆变器便时时刻刻监视太阳电池组件的输出，只要太阳电池组件的输出功率大于逆变器工作所需的输出功率，逆变器就持续运行；直到日落停机，即使阴雨天逆变器也能运行。
当太阳电池组件输出变小，逆变器输出接近0时，逆变器便形成待机状态。
2、最大功率跟踪控制功能太阳电池组件的输出是随太阳辐射强度和太阳电池组件自身温度（芯片温度）而变化的。
另外由于太阳电池组件具有电压随电流增大而下降的特性，因此存在能获取最大功率的最佳工作点。
太阳辐射强度是变化着的，显然最佳工作点也是在变化的。
