Abstract
The present invention discloses a flying capacitor converter, a short circuit current suppression circuit for the same and an energy storage system. The flying capacitor converter comprises a controller, and has a high voltage side connected to a first power source and a low voltage side connected to a second power source. The short circuit current suppression circuit comprises: at least one current detection unit connected to the low voltage side and/or the high voltage side of the flying capacitor converter; and at least one switch set connected in series to the high voltage side and/or the low voltage side of the flying capacitor converter, wherein the controller controls the switch set to cut off a connection between the flying capacitor converter and the first power source and/or between the flying capacitor converter and the second power source, when the current detection unit detects a short circuit.
