摘要

Abstract >A novel circuit topology for a single‐phase inverter with a power decoupling capability operated in discontinuous current mode (DCM) is proposed in this paper. An inverter connected to a single‐phase grid requires a power decoupling capability to compensate for a power ripple with twice the grid frequency. Bulky capacitors are used as DC‐link capacitors in conventional systems. In contrast, the proposed circuit topology can use ceramic capacitors instead of electrolytic capacitors by reducing the required capacitance based on the active buffer concept. Moreover, this active buffer requires no additional inductor because it uses DCM for the power decoupling capability. In this paper, a control method for the active buffer circuit operated in DCM is introduced. An experimental verification of a 1‐kW prototype shows that the proposed circuit reduces the input current ripple at twice the grid frequency by 96.8%, with a maximum efficiency of 95.2%. In addition, the Pareto optimization of power density and efficiency is used to clarify the maximum power density points. It is found that the maximum power density of the proposed circuit is 1.6 times higher than that of a conventional boost‐type active buffer. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract XMLNS =“http://www.wiley.com/namespaces/wiley”type =“main”xml：lang =“en”> <标题类型=“main”>抽象</ title> <P>本文提出了具有以不连续电流模式（DCM）运行的功率去耦能力的单相逆变器的新型电路拓扑。连接到单相网格的逆变器需要功率去耦能力，以补偿具有两倍电网频率的功率纹波。庞大的电容器用作传统系统中的DC-Link电容器。相反，所提出的电路拓扑可以通过基于主动缓冲概念减少所需的电容来使用陶瓷电容器而不是电解电容器。此外，该活动缓冲区不需要额外的电感，因为它使用DCM进行功率解耦能力。在本文中，引入了在DCM中操作的主动缓冲电路的控制方法。一个KW原型的实验验证表明，所提出的电路将输入电流纹波减小到电网频率的两倍于96.8％，最大效率为95.2％。此外，使用功率密度和效率的Pareto优化来阐明最大功率密度点。发现所提出的电路的最大功率密度比传统增压型活性缓冲液的最大功率密度高1.6倍。</ p> </摘要> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-22399/'>《Electrical engineering in Japan》</a> <b style="margin: 0 2px;">|</b><span>2018年第2期</span><b style="margin: 0 2px;">|</b><span>共11页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Itoh Jun‐ichi&option=202" target="_blank" rel="nofollow">Itoh Jun‐ichi;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Sakuraba Tomokazu&option=202" target="_blank" rel="nofollow">Sakuraba Tomokazu;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Le Hoai Nam&option=202" target="_blank" rel="nofollow">Le Hoai Nam;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Watanabe Hiroki&option=202" target="_blank" rel="nofollow">Watanabe Hiroki;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Kusaka Keisuke&option=202" target="_blank" rel="nofollow">Kusaka Keisuke;</a> </p> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zkzz" style="display: none;">展开▼</span> </div> </li> <li> <div style="display: flex;"> <span class="lefttit">作者单位</span> <div style="position: relative;margin-left: 3px;max-width: 639px;"> <div class="threelineshidden zhankaihshouqi" id="fOrgthree"> <p>Nagaoka University of TechnologyNiigata Japan;</p> <p>Nagaoka University of TechnologyNiigata Japan;</p> <p>Nagaoka University of TechnologyNiigata Japan;</p> <p>Nagaoka University of TechnologyNiigata Japan;</p> <p>Nagaoka University of TechnologyNiigata Japan;</p> </div> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zhdw" style="display: none;">展开▼</span> </div> </div> </li> <li > <span class="lefttit">收录信息</span> <span style="width: 86%;vertical-align: text-top;display: inline-block;"></span> </li> <li> <span class="lefttit">原文格式</span> <span>PDF</span> </li> <li> <span class="lefttit">正文语种</span> <span>eng</span> </li> <li> <span class="lefttit">中图分类</span> <span><a href="https://www.zhangqiaokeyan.com/clc/1782.html" title="输配电工程、电力网及电力系统">输配电工程、电力网及电力系统;</a></span> </li> <li class="antistop"> <span class="lefttit">关键词</span> <p style="width: 86%;vertical-align: text-top;"> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=active buffer circuit&option=203" rel="nofollow">active buffer circuit;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=discontinuous current mode&option=203" rel="nofollow">discontinuous current mode;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=single‐phase AC grid‐connected inverter&option=203" rel="nofollow">single‐phase AC grid‐connected inverter;</a> </p> <div class="translation"> 机译：主动缓冲电路;不连续电流模式;单相交流电网连接逆变器;
