Abstract:
In this paper, a novel DC-DC buck-boost converter with a wide conversion ratio is introduced. With the advantages of the ZETA converter, such as continuous input current and positive polarity of the output voltage, the proposed buck-boost converter is well suited to industrial and renewable energy applications. With a voltage gain higher than the ZETA converter, the proposed converter also reduces input current stress due to its continuity. Two operating states are available for this converter in continuous conduction mode (CCM). This converter has two switches that operate simultaneously, and it can be controlled easily. As a result of the converter's continuous output current, output voltage ripple and output capacitor current stress are reduced. Computational analysis, small signal modeling and efficiency of the proposed converter considering the influence of parasitic elements are presented in this paper. This converter has also been compared with other similar and recently presented topologies. Finally, a prototype is implemented to verify the accuracy of the computational analysis, and simulation and experimental results are presented.
