Synchronous Combined Cuk-SEPIC Converter for Single Phase Transformerless Solar Inverter

Project Code :TEPGPE64

Objective

The main objective of the project is to completely eliminate the common-mode voltage and to reduce DC bus capacitance required for active power decoupling.

Abstract

In this project, a bidirectional power electronic converter based on the Synchronous Combined Cuk-SEPIC converter has been presented for single-phase transformer less solar power generation systems. The proposed topology completely eliminates the common-mode voltage, hence the common-mode current.

The proposed converter generates a bipolar output with respect to the common ground; hence a simple half-bridge can be used for grid integration. The proposed synchronous operation allows significant reduction of the DC bus capacitance required for active power decoupling compared to the previously reported asynchronous operation. Simulation results of the converter at full load with lagging, leading, and unity power factor conditions are evaluated using MATLAB/SIMULINK.

Keywords: Synchronous Combined Cuk-SEPIC converter, Single Phase Transformer-less Solar Inverter, the DC bus capacitance, common-mode voltage, common-mode current.
