High step‐up combined boost‐Cuk converter with switched‐inductor
View through CrossRef
AbstractIn this paper, a novel boost‐Cuk converter topology based on the combination of a boost and Cuk converters is proposed. The converter has the characteristics of boost and Cuk converters, voltage gain is improved, and the input and output current of the converter is continuous. To further enhance the voltage gain, switching inductance technology is introduced. The proposed converter is designed using magnetic integration, and the influence of magnetic coupling technology on inductance current ripple is theoretically investigated to obtain the converter's minimum inductance current ripple design. A prototype is realised to confirm the validity of the theoretical analysis and the operation of the proposed converter.
