Abstract: A conversion circuit is disclosed and includes a DC link, a first DC-to-DC converter, an inverter and a second inverter. The DC link includes DC link rails. The first DC-to-DC converter includes a first phase leg and a second phase leg. The first reactor is connected between a first center terminal of the first phase leg and at least one energy storage module. The second reactor is connected between a second center terminal of the second phase leg and the at least one energy storage module. The first reactor, the at least one energy storage module and the second reactor are connected in series between the first center terminal and the second center terminal such that the first DC-to-DC converter has a virtual ground.

Abstract: A DC-DC auto-converter module includes a positive source terminal, a negative source terminal, a positive load terminal, a negative load terminal, and a DC-DC converter. The negative source terminal cooperates with the positive source terminal to facilitate electrical connection of a DC power source thereto. The negative load terminal cooperates with the positive load terminal to facilitate connection of an electrical load thereto. The isolated DC-DC converter comprises an input circuit and an output circuit that is galvanically isolated from the input circuit. The DC-DC converter includes a positive input terminal, a negative input terminal, a positive output terminal, and a negative output terminal. At least one of the positive input terminal, the negative input terminal, the positive output terminal, and the negative output terminal is galvanically connected to at least one of the positive source terminal, the negative source terminal, the positive load terminal, and the negative load terminal.
