Abstract
The necessity for DC−DC converters has been rapidly increasing due to the emergence of RES-based electrification. However, the converter designed so far exhibits the drawbacks of lower efficiency and non-compactness in size. Hence, to rectify this problem, the new topology of a flyback converter for PV application is proposed in this work. The proposed converter exhibits reduced ripple in input current and enhances the conversion efficiency. Finally, the efficiency of this proposed converter is verified using MATLAB. The results indicate that this projected topology can be suitable for high voltage DC applications.
Highlights

A hybrid DC−DC converter was designed for high power applications
This is the combination of a Luo converter with a flyback converter
Summary
Isolated DC−DC converters have been extensively utilized in many higher power applications, because of their higher efficiency, easy voltage gain and lower ripple content. The traditional DC−DC converters, namely BOOST and buck boost topology, exhibit high ripple content as their output [1,2,3,4] The Luo converters are becoming more popular due to their high output gain and less voltage ripple at the output [17,18,19,20].While designing the converters, the switches play a major role This has led to the development of multichip power modules (PMs) using SiC MOSFETs [21]. This approach is utilized while designing a DC converter for renewable energy applications Keeping this in view, this work proposed a hybrid combination of the Luo with flyback converter which exhibits a higher voltage gain and less ripple content with SiC MOSFETs as switches.
