Abstract

Solar Energy Conversion Systems (SECS) are trending one among all other renewable energy conversion systems. One of the important shortcoming in SECS, which acts as a barrier for its preference is energy conversion efficiency. This research work presents the performance analysis of SECS with the integration of advanced DC-DC converter namely Super-Lift Luo Converter (SLLC). Traditionally, Boost converter is widely used in SECS for improvement of efficiency. The drawbacks of Boost converter integrated SECS are clearly addressed in this manuscript by considering quality and efficiency of energy conversion. Unlike the Boost converter, the proposed SLLC converts DC output voltage from solar panel in geometric progression. The ripple content in the output voltage is highly reduced in SLLC integrated SECS compared with Boost converter integrated SECS. In this work, the SECS designed to feed a DC motor (DCM) and hence, the DC-DC converter is allowed to operate in open loop control. The designed SECS is simulated using MATLAB / SIMULINK software. The simulation results like DC output voltage, ripple content, speed response of DCM and electromagnetic torque validates the choice of SLLC over Boost converter in SECS.

采用超升力罗式变换器的太阳能转换系统性能分析

太阳能转换系统(SECS)是所有其他可再生能源转换系统的趋势之一。能量转换效率是影响SECS技术发展的重要因素之一。本文研究了集成先进DC-DC变换器即超升力罗变换器(SLLC)的SECS的性能分析。传统上，升压变换器被广泛应用于SECS中以提高效率。本文通过对能量转换质量和效率的考虑，明确地解决了升压变换器集成SECS的缺点。与升压变换器不同，所提出的SLLC以几何级数转换太阳能电池板的直流输出电压。与升压变换器集成SECS相比，SLLC集成SECS的输出电压纹波含量大大降低。在这项工作中，SECS设计用于馈送直流电机(DCM)，因此，允许DC-DC转换器在开环控制中运行。利用MATLAB / SIMULINK软件对设计的SECS进行了仿真。直流输出电压、纹波含量、DCM速度响应和电磁转矩等仿真结果验证了SECS中SLLC比Boost变换器的选择。
