A family of non-isolated DC/DC converters capable of continuous input and output current flows suitable for aerospace applications

A family of non-isolated converters capable of continuous input and output current flows is proposed in this paper. The converters have the characteristics of low input and output current ripple, which are very suitable for spacecraft applications. Based on the analysis of the conventional non-isolated topology, this paper derives a family of non-isolated converters having both input and output currents flowing continuously through configuring, combining converter cell and rotating its terminals, as well as considering the basic principle of continuous inductor current flow. The derivation and the topological analysis are presented. One of the proposed topologies is given as an example and verified by an experimental prototype, which indicates that the proposed topology can achieve the characteristic of continuous input and output currents.
