介绍了一种新型的非隔离降压-升压DC-DC变换器。所建议的结构的交错配置增加了电压转换比。所建议的转换器的电压率可以逐步上升和逐步下降的占空比的值较低，这将导致减少系统的传导损耗。推荐结构的电压转换比在整个半导体元件中具有低的最大电压。另外，仅利用一个功率开关便于转换器控制。使用具有小导通电阻的单个功率MOSFET RDS-ON可提高推荐拓扑的整体效率。为了验证所提出的转换器的性能，在文献中提供了技术描述、数学测量以及与类似结构的比较研究。最后，一个实验室计划与100 W的负载功率率在50 kHz的开关频率进行，以证明所提出的转换器的有效性。
This work introduces a new non-isolated buck-boost DC-DC converter. Interleaved configuration of the suggested structure increases the voltage conversion ratio. The voltage rate of the suggested converter can be stepped-up and stepped down for lower values of duty-cycle, which causes to decrease in the conduction losses of the system. The voltage conversion ratio of the recommended structure is provided with low maximum voltage throughout the semiconductor elements. Additionally, utilizing only one power switch facilitates converter control. Using a single power MOSFET with small conducting resistance, RDS-ON, increases the overall efficiency of the recommended topology. To verify the performance of the presented converter, technical description, mathematical survey, and comparison investigation with similar structures are provided in the literature. Finally, a laboratory scheme with a 100W load power rate at 50 kHz switching frequency is carried out to demonstrate the effectiveness of the proposed converter.
