Abstract
The use of dc technology was almost discarded in the power transmission systems. DC power systems have been used in applications like avionic, automotive, marine, rural areas, telecommunication infrastructures and point-to-point transmissions over long distances or via sea cables and for interconnecting ac grids with different frequencies. This Paper describes a new application of single-ended primary converter (SEPIC) and Cuk converter for dc bipolar network. A dc–dc converter configuration based on a combination of both converters is proposed. In the resulting topology, the switching node is shared by the SEPIC and Cuk converter since they have the same instantaneous duty cycle. The main advantage of this topology is that synchronization of various switches is not required and control terminal is connected to ground which simplifies the design of the gate drive. On the other hand, this configuration allows the connection of renewable energy sources to microgrids (MG)-type bipolar dc link and to cover the current needs of new distributed generation units with efficient, economical, and easy way. To verify its performance, MATLAB/Simulink platform is used.
