Unified multimode modelling, stability analysis, and reinforced sliding‐mode design of high‐order buck/boost DC–DC converters for DC energy systems

Abstract Unified modelling, analysis, and reinforced sliding‐mode design of a high‐order buck/boost converter are proposed for DC energy systems. The high voltage gain with low current stress on the converter’s circuit components will noticeably improve its performance in DC energy systems. The math...
