摘要

SUMMARY >Analysis precision of boost ratio and power efficiency in boost DC–DC converter circuit is improved by proposing adaptive equivalent circuit of output diode of the circuit. In experiment, boost ratio and power efficiency in high boost ratio circuit were 9.89% and 76.5% respectively with its load resistance of 20 Ω driven by output voltage 10 V. In experimental results, error in theoretical values of boost ratio compared with the measured values of that was reduced to ?3.79% from 57.5% in the conventional circuit. In a tapped‐inductor high boost ratio circuit, error in theoretical values of boost ratio was reduced to 3.54% from 31.8%. Error in theoretical values of power efficiency with the measured values of that was reduced to 5.51% from 33.2% in the conventional circuit. In a high boost ratio circuit, error in theoretical values of power efficiency was reduced to ?3.32% from 17.3%. Power loss of every element in boost DC–DC converter circuits was analyzed with high precision by analysis of inductance current waveforms in those circuits. Error in theoretical values of power loss compared with measured values was reduced to equal or less than 5%. </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”> <title type =“main”>摘要</ title> >分析精度通过提出电路输出二极管的自适应等效电路，提高了升压比率和功率效率。在实验中，高升压比电路的升压比率和功率效率分别为9.89％和76.5％，其负载电阻分别由输出电压10V驱动的20Ω。在实验结果中，与测量值相比，升压比的理论值误差其中的常规电路中的57.5％减少了3.79％。在Tape-Infuctor高升压比电路中，升压比的理论值误差从31.8％降低到3.54％。功率效率的理论值误差，测量值在传统电路中从33.2％降至5.51％。在高升压比电路中，功率效率的理论值误差减少到17.3％的3.32％。通过在这些电路中分析电感电流波形，通过高精度分析了升压DC-DC转换器电路中每个元件的功率损耗。与测量值相比，功率损耗的理论值误差降低到等于或小于5％。</ 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4期</span><b style="margin: 0 2px;">|</b> <span>共18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=LIU YUHAN&option=202" target="_blank" rel="nofollow">LIU YUHAN;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=SEKIGUCHI RYO&option=202" target="_blank" rel="nofollow">SEKIGUCHI RYO;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=SANO YUJI&option=202" target="_blank" rel="nofollow">SANO YUJI;</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>Toyo UniversityJapan;</p> <p>Toyo UniversityJapan;</p> <p>Toyo UniversityJapan;</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=switched‐mode power supply&option=203" rel="nofollow">switched‐mode power supply;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=DC‐DC converter&option=203" rel="nofollow">DC‐DC converter;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=boost circuit&option=203" rel="nofollow">boost circuit;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=boost ratio&option=203" rel="nofollow">boost ratio;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=power efficiency&option=203" rel="nofollow">power efficiency;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=analysis&option=203" rel="nofollow">analysis;</a> </p> <div class="translation"> 机译：开关模式电源;DC-DC转换器;升压电路;升压率;功率效率;分析;
