A New High Step-Up DC-DC Converter for Renewable Energy Applications
- 597 Downloads
This paper presents a new non-isolated boost converter with high boost ability and low voltage stress on the main switch. The proposed converter uses a hybrid switched-inductor (SL)/switched-capacitor (SC) technique to couple with an active switched network. The proposed converter is very suitable for many industrial applications such as photovoltaic (PV) and fuel-cell. A multicell hybrid SL/SC structure of the proposed converter is also derived in order to get a higher boost ratio. The operation principle, parameter design, and comparison with other converters are given. A laboratory prototype with the closed-loop control is designed for test, and both simulation and experimental results are given to demonstrate the effectiveness of the proposed converter.
