Abstract
Objective: A hybrid converter system gives a continuous power flow across load and designed for a high power and high voltage application. Methods: The proposed paper introduces a hybrid Cuk-SWISS converter system for photovoltaic and AC-grid interface system. The aim of hybrid converter topology is to generate a high voltage and power generation for applying industrial high power application. Photovoltaic system is used as secondary power source of the proposed hybrid converter whereas, the primary power sources are applied through AC-grid power supply. Findings: Cuk converter system is used to integrate photovoltaic power to hybrid scheme, whereas SWISS Converter is integrated for AC-grid power to hybrid converter scheme. Those two converter are connected internally for purpose of reducing reverse recovery problem and to provide same and simultaneous power supply regulation across the load. Power factor correction and control of grid current is drawn by SWISS converter whereas leading of current regulation and high voltage generation using low range of passive elements is drawn by Cuk converter. The performance of high voltage and high power conversion is verified using MATLAB/Simulink Results. Improvement: Proposed Hybrid converter system is an integrated form of AC/DC-DC conversion topology which helps in controlling the load current and improves voltage over single converter topology.
