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.
