Comprehensive Review of KY Converter Topologies, Modulation and Control Approaches with their Applications

Abstract

In the current scenario, the challenging task of designing a DC-DC converter has high voltage gain and small output ripple waves, which researchers deal with in highly complicated Because of its topological and continuous conduction mode (CCM), the KY converters have developed a better converter than all the traditional DC-DC converters to overcome this intricacy of voltage transfer gain and output ripple waves. The KY converters had various qualities when compared with the boost converter with Synchronous Rectifier (SR). The KY converter is used in photovoltaic and sustainable power applications, which are examined in this study. For example, the KY converter incorporates mode-1 and mode-2 operation and its types, for example, one plus D and one plus 2D, where the KY can deliver the Nth type of KY converter. This article provides a comprehensive review and investigation of the KY converters, which incorporates their topology with control methodologies, Pulse Width Modulation (PWM) techniques, working activity of KY converters, and types for mode-1 and mode-2; it interprets the few strategies the KY converter executes and its applications.
