Classification: CPC H  Y | IPC H

Claim 0:
1. A power converting device comprising:
a first input terminal electrically coupled to a battery;
a second input terminal electrically coupled to a power generation device;
a switching module including a plurality of upper arm switching elements connected in parallel between a first node and a second node and a plurality of lower arm switching elements connected in parallel between a third node and a fourth node, and configured to switch between at least one of a first DC voltage between the first input terminal and a direct current (DC) terminal and a second DC voltage between the second input terminal and the DC terminal;
a DC link capacitor provided at the DC terminal;
a first relay switch provided between the first input terminal and the switching module; and
a second relay switch provided between the second input terminal and the switching module,
wherein each of the first relay switch and the second relay switch is electrically connected to the third node,
wherein the first input terminal and the DC terminal are electrically connected via at least one of the plurality of lower arm switching elements when the switching module operates to receive power from the power generation device, and
wherein the second input terminal and the DC terminal are electrically connected via at least one of the plurality of upper arm switching elements when the switching module operates to charge the battery.
