Abstract
A flying capacitor converter, a voltage converter and an energy storage system are provided. The flying capacitor converter includes a high-voltage side, a low-voltage side, a power switch unit, a current switch unit and a current detection unit. The high-voltage side is electrically connected with a first power source. The low-voltage side is electrically connected with a second power source. The power switch unit is electrically connected between the high-voltage side and the low-voltage side and includes three terminals and four power switches. The current switch unit is electrically connected with the high-voltage side, the low-voltage side and/or a common node. The current detection unit is electrically connected between a third terminal of the power switch unit and the common node. If the current detected by the current detection unit indicates that a short-circuit condition occurs, the power switch unit is disconnected from the high-voltage side and/or the low-voltage side.
