A New Buck-Boost Converter Structure With Improved Efficiency
In this paper presents a New Buck-Boost structure with high performance, suitable for practical applications. The performance is evaluated based on direct measurements of voltage and current in the circuit, minimizing errors and producing accurate results. The article compares the proposed Buck-Boost converter with two other converters, the Transformerless Buck-Boost Converter With Positive Output Voltage (Positive Step Buck-Boost - PSBB) and the Negative Output Buck-Boost Converter With Wide Conversion Ratio (Negative Step Buck-Boost - NSBB). The results show that the proposed converter outperforms the other two converters in terms of performance. To validate the proposed design, simulation results obtained using PSIM software are presented in the form of graphs.
