Abstract

The proposed work is extended configurations of Modified SEPIC Converter (MSC) and Modified SEPIC Converter with Switched Module (MSCSI). The proposed three configurations are derived by replacing two inductor of MSC by two Switched Inductor (SI) modules, namely Modified SEPIC Converter with XYL configuration (MSCSI-XYL), Modified SEPIC Converter with LYZ configuration (MSCSI-LYZ) and Modified SEPIC Converter with XLZ configuration (MSCSI-XLZ) to improve or increase the overall gain of the converter. The key feature of proposed configuration is: (i) single switch topologies, (ii) no reverse current flow from load to source due to large inductor at the input side, (iii) high voltage conversion ratio. The detailed analysis of three configurations is done in terms of component count, voltage conversion ratio and efficiency. The mathematical analysis and simulation results validates the functionality of three configurations.

光电应用中带有开关电感模块(MSCsI)的改进型SEPIC变换器的配置:第二部分

提出的工作是改进SEPIC转换器(MSC)和改进SEPIC转换器带交换模块(MSCSI)的扩展配置。通过用两个开关电感(SI)模块替换MSC的两个电感，得到了三种配置，即改进型SEPIC变换器与XYL配置(MSCSI-XYL)，改进型SEPIC变换器与LYZ配置(MSCSI-LYZ)和改进型SEPIC变换器与XLZ配置(MSCSI-XLZ)，以改善或增加变换器的整体增益。所提出的配置的关键特征是:(i)单开关拓扑结构，(ii)由于输入侧的大型电感，没有从负载到源的反向电流，(iii)高电压转换比。从元件数、电压转换比和效率三个方面对三种配置进行了详细的分析。数学分析和仿真结果验证了三种结构的功能。
