Abstract: An arrangement for forming a thermally insulated wall is provided that includes two panels connected to one another by multiple connecting means, wherein each connecting means has two receiving openings. Each panel is provided with an insertion opening, and a fixing means is inserted into the receiving opening of the connecting means through the insertion opening. Each of the connecting means includes a holding means of a first kind configured to hold a horizontal reinforcing means that connects the connecting means to one another and a holding means of a second kind configured to hold a vertical reinforcing means that connects the connecting means to one another. Other aspects are described and claimed.

Abstract: The application relates to an electric converter for converting AC or DC input into an electric AC or DC output. A swap circuit with controllable electric switches serves to selectively swap connection of a plurality of DC power banks (DCBs) between an input terminal and an output terminal, thus selectively connecting the DCBs to an electric source or an electric load. The DCBs are formed as series of interconnected submodules (SMs) each having electric energy storage elements (ESEs) and a switching circuit for selectively by-passing or connecting the ESEs. By properly controlling the swap circuit and the switching of the SMs, the converter can be used for DC-AC, DC-DC, AC-DC, or AC-AC conversion, allowing multilevel output.

A swap circuit with controllable electric switches serves to selectively swap connection of a plurality of DC power banks (DCBs) between an input terminal and an output terminal, thus selectively connecting the DCBs to an electric source or an electric load. The DCBs are formed as series of interconnected submodules (SMs) each having one or more electric energy storage elements (ESEs) and a switching circuit for selectively by-passing or connecting the ESEs. The ESEs can be capacitors, batteries, super capacitors, or a combination of these. By properly controlling the swap circuit and the switching of the SMs, such as by taking into account the dead-time for the electric switches involved, the converter can be used for DC-AC, DC-DC, AC-DC, or AC-AC conversion, allowing multilevel output.

Abstract: A thermal insulated building element is constructed together with connecting elements, and is suitable for making a building system quickly, and is also suitable for housing and extract fastening of any reinforcement. The thermal insulated element has polystyrene elements with a loadboarding part containing a metal framework between the polystyrene elements said loadbearing part is filled with concrete in-site, furthermore has connecting elements joining the polystyrene elements. The polystyrene elements (1) are plastic connecting elements (19) where fastening holes (8) serving joining the polystyrene elements as well as the nests (20) joining a framework (18) in a space (30) between the polystyrene elements. The plastic connecting elements are passed through an outside wall of one of the polystyrene elements and fixed into the respective polystyrene elements at the outside by clamping profiles which are led through the fastening holes placed in the polystyrene elements.
