Abstract

With rapid advancement of DC-DC converter, the non-isolated dc-dc converters has caught much attention from academia and industry, owing to its advantages including low cost and compacted structure. Especially, the non-isolated dc-dc converters have taken the dominant position in topology design of power source. This paper introduces the concept of output section evolution in non-isolated dc-dc converters, with the aim of integrating high ratio voltage boosting capacity. To achieve this, a series of novel output enhanced circuits are proposed and discussed in detail. These circuits are structured using capacitors and diodes, making them applicable to various positive output dc-dc converters. Notably, the derived topologies in this paper eliminate the need for additional power switches and transformers. The effectiveness of the proposed approach is demonstrated through application cases based on both the classical boost converter and the developed voltage-lift SEPIC converters. These cases showcase the practical application and benefits of the proposed method. By following the topology construction method outlined in the paper, engineers can gain valuable insights and guidelines for designing circuits in the field of power electronics. Theoretical analysis has been verified in experimental prototype and the provided resources also serve as an educational tool for those studying power electronics engineering.
