A comparison of high-power DC-DC soft-switched converter topologies

The purpose of this paper is to compare the properties of several soft-switching converter topologies when used to achieve DC-DC conversion at high-power and high-voltage levels. As an example, a 100 kW transformer isolated converter with 700-1400 Vdc input is designed with an estimated mass in the...

Description
Summary:The purpose of this paper is to compare the properties of several soft-switching converter topologies when used to achieve DC-DC conversion at high-power and high-voltage levels. As an example, a 100 kW transformer isolated converter with 700-1400 Vdc input is designed with an estimated mass in the 90-kg range and an energy efficiency of 95%.
