A Single-switch Non-isolated High Gain DC/DC Converter for PV Applications

Abstract

In this paper a single switch non-isolated high voltage gain DC/DC converter based on the conventional converter and a switched inductor is introduced. The operation and analysis of the converter in the continuous conduction mode (CCM) and discontinuous conduction mode (DCM), and voltage gain equation derivation are also presented. Also, design of the converter parameters (inductors and capacitor) is given. The proposed converter achieves continuous input current that suitable for PV applications. Also, it is characterized by simplicity of installation and eases of operation which decreases the power losses and gives high overall efficiency. A prototype is made in laboratory to validate the effectiveness of the proposed converter. The proposed converter operation is tested experimentally with static and dynamic load. Also, the performance of the proposed converter is examined with an open loop and closed loop controllers. In addition, a comparison between the proposed converter and other recent converters is also introduced to confirm the merits of this converter.

Design and Implement of Step-Up DC-DC Converter with a Professional Approach using MATLAB/Simulink

“…This duration's ratio to the total switching time period is termed the switching duty cycle, denoted as D, as described by. The investigation primarily centers on continuous current mode operation, which, in this analysis, is denoted as the continuous positive cycle throughout the switching process [11] [12]. The adoption of continuous current mode operation in this study is aimed at achieving enhanced regulation within the circuit.…”
