In order to reduce switching losses and improve overall efficiency, various soft switching circuit topologies have been researched, developed, and utilized. For boost converter topology, ZVT soft switching boost converter with lossless snubber developed by Katsunori Taniguchi is one of soft switching converters that have been proposed. By connecting an auxiliary circuit composed of a resonance inductor, resonance capacitors, auxiliary switches, and auxiliary diodes, the key waveforms shown that not only main switch which turns on under zero voltage transition (ZVT) and turns off by zero voltage switching (ZVS), but auxiliary switches also operate under zero current switching (ZCS) turn on and zero voltage switching turn off. Besides, the control scheme can be conducted without complexity since both auxiliary switches are turned on simultaneously with constant on duration and turned off at the time that main switch is turned on. The operation and soft switching conditions of proposed converter have been verified by simulation results. Moreover, the simulation results shown that the proposed converter achieved higher efficiency than the conventional boost converter and ZVT boost converter._x000D_\n_x000D_\nZVT soft switching boost converter with lossless snubber has some certain characteristics which are needed to be considered. Specifically, some combinations of resonance components value in auxiliary circuit might causes excessive current stress in power electronics components, as well as auxiliary switches turn on duration which affects soft switching condition of main switch. Therefore, a design criterion of each component is needed to be considered. In this paper, the design considerations of proposed ZVT soft switching boost converter are presented. By deriving mathematical expressions from each operation mode, voltage and current level of each component along with resonance duration can be considered. To utilize the expressions, several conditions are needed to be determined. For example, acceptable current stress level of each power electronics component, or acceptable on duration of auxiliary switches. After the calculation, approximate value of resonance inductor and capacitors can be determined. Consequently, the simulation of proposed circuit was conducted by using the calculated value of components. According to the simulation results, each mathematical expression is verified to be useful for design considerations of the proposed converter, current stress of power electronics devices is in acceptable level while soft switching turn on and off of both main and auxiliary switches are satisfied._x000D_\n_x000D_\nFurthermore, in addition to the design considerations and simulation, the experiment of proposed converter was conducted. The results shown that, although the waveforms of current and voltage of components from experiment are not certainly identical with the one from simulation results due to the effect of parasitic components, soft switching conditions of switching components in the circuit are still satisfied even in light load condition. In term of efficiency, the proposed converter achieved higher efficiency than the conventional one all over the continuous conduction mode (CCM) region. \u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e原稿種別: \u003c\/strong\u003e英語\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePDFファイルサイズ: \u003c\/strong\u003e1,601 Kバイト\u003c\/p\u003e","brand":"IEEJ-PDF","offers":[{"title":"PDFダウンロード（一般価格330円\/会員価格220円） \/ A4 \/ 6","offer_id":46393330467055,"sku":"IEEJ-SPC16036MD16036-PDF","price":330.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0718\/9512\/2159\/files\/IEEJ-PDF_aeb7d305-5b46-4a73-a76a-1551ee990386.png?v=1744688198","url":"https:\/\/ieej.bookpark.ne.jp\/products\/ieej-spc16036md16036","provider":"電気学会 電子図書館","version":"1.0","type":"link"}
