本論文提出使用變壓器之倍壓箝位交錯順向式高昇壓轉換電路,變壓器為順向模式,且輸出電容為串聯形式,可實現整體電路之高昇壓轉換比。利用箝位電路之倍壓技術與無損耗被動箝位功能。如此不但提升電壓增益轉換,且變壓器之漏感能量可回收至輸出端,同時可抑制開關突波電壓,使轉換電路效率提高。且功率開關為低電壓應力,元件可選用低導通內阻(Rds(ON))之MOSFET,減少導通損耗,架構之效率藉此提高。所提出新型交錯式高昇壓轉換電路做實際測試,以驗證高效率之可行性與電路特性,其規格為輸入電壓24V、輸出電壓380V與額定功率1kW。最高效率為300W之96.24%,滿載1kW效率為92.57%。
This paper present novel interleaved high step-up converter with transformer and voltage doubler of clamp circuit. Transformer is a forward rectified output, and the output capacitor is in series, which achieve the high boost conversion ratio of the overall circuit. The converter utilize voltage multipilier techniques of clamp circuit and the passive lossless clamped function. Not only to enhance the voltage gain conversion,but also the leakage energy of ideal transformer to be recycled to output terminal, which alleviates the voltage spike across switch, The converter can lift the conversion efficiency.The power switch is low voltage stress and components are available low conduction resistance(Rds(ON)) of MOSFET. To reduce the conduction loss, and the efficiency of the structure to improve.
The specification of the proposed converters for performance verification and circuit characteristics are shown as below:The proposed converter is tested with input voltage 24V, output voltage 380V and maximum power 1kW. The proposed converter highest efficiency is 96.24% in the 300W, 1kW full load efficiency is 92.57%。
