Series SEPIC implementing voltage-lift technique for DC-DC power conversion

摘要: The voltage-lift technique is an effective method that could be applied in electronic circuit design. A set of positive output DC-DC converters applying series SEPIC implementing techniques introduced. Compared with the prototype converter, these can perform to voltage increasing conversion higher transfer gains. They are different from other existing step-up and possess obvious advantages, mainly including fewer switches, clear processes a high small ripples. Since proposed avoid using transformers cascade connection, relative simple structures beneficial potential practical applications future. detailed theoretical analysis for continuous discontinuous conduction modes given. Both simulation experimental results provided verify main characteristics.
