Galvanically isolated switched-boost-based DC-DC converter

A new galvanically isolated DC-DC converter has been presented in this paper. The proposed topology is based on the quasi-switched-boost impedance network. It not only includes all positive characteristics of previous converters including continuous input current, high boost ability and high efficiency, but also has the prominent features of less passive elements utilization, small size and light weight. The proposed converter has been analyzed and inspected in the steady state. Furthermore, other possible galvanically isolated switched boost dc-dc topologies have been obtained by altering the switching network. Theoretical analysis has been verified by simulations as well as the experiments
