Abstract: A cable clamping assembly includes a cable clamp and a supporting base. The cable clamp includes a protruding base and two bendable arms. The protruding base has an opening disposed on the center of a top surface. The two bendable arms respectively include a plurality of first latching components and a plurality of second latching components. The supporting base includes a concave portion. A guiding slope and a positioning portion are disposed within the concave portion. When the cable clamp clamps a cable, the two bendable arms respectively slide downwardly along two ends of the guiding slope to surround the cable, until one of the two bendable arms is stopped by the positioning portion. The protruding base is deformed in response to a pressing force, so that the bendable arms tie the cable closely, and the plurality of first latching components lock with the plurality of second latching components.

Abstract: A power conversion system is coupled between a power grid and a load. The power conversion system includes a battery, a first converter, a second converter and a DC/DC converter. The first converter is configured to selectively convert an input power from the power grid into a first charging power when the power grid is operated normally. The second converter is configured to convert the input power from the power grid into an output power when the power grid is operated normally. The DC/DC converter is electrically connected between the battery and the second converter. The DC/DC converter is configured to convert a storage power in the battery into a backup power when the power grid is not operated normally.
