摘　　要：提出一种新型的高升压DC-DC变换器。该变换器输入侧采用Boost结构,因此继承了输入电流连续的优点,适合用于可再生能源应用。变换器后级利用三绕组耦合电感和倍压单元进行集成,从而能够使用较小总匝比的耦合电感获得高电压增益,且提高电压增益的调节自由度。开关管电压应力低,可使用低耐压器件。此外,钳位支路回收储存在耦合电感漏感中的能量,从而提高效率。该文对变换器的工作模态进行详细讨论,并与其他变换器的性能进行对比。最后,搭建一台实验样机进行验证,实验获取的数据结果与理论层面的分析高度契合。This article puts forward a brand-new high-boost DC-DC converter.The converter adopts a Boost structure on the input side,inheriting the advantages of continuous input current,making it besuitable for renewable energy applications.The rear stage of the converter integrates the three-winding coupled inductor and the voltage double unit.As a result,a high voltage gain can be achieved by using a coupled inductor with a relatively small total turn ratio,and the degree of freedom in adjusting the voltage gain is also improved.The low switch voltage stress allows the use of low voltage rating devices.Additionally,the clamping circuit reutilizes the energy stored in the leakage inductance of the coupled inductor,thereby enhancing the efficiency.The article discusses the operating modes of the converter in detail and compares its performance with other converters.Finally,an experimental prototype is built for verification,and the experimental results match the theoretical analysis.
