Abstract: An electric system comprising communication link between a signal transmitting end and a signal receiving end, wherein, at the signal transmitting end, a number of data bits are integrated into a low frequency signal to form an integrated signal. Each data bit is transmitted as part of a symbol. Each symbol comprises a predefined number of bits encoding at least one data bit, the state of some of the bits of each symbol being dependent on the state of the low frequency symbol.

Abstract: A method for a direct current (DC) power distribution arrangement and a direct current (DC) power distribution arrangement, comprising a plurality of DC power distribution subsystems. Each DC power distribution subsystem comprises an inverter unit (INU) configured to operate as a subsystem-specific circuit breaker for intercoupling / separating the DC power distribution subsystem to / from the rest of the DC power distribution arrangement.

Abstract: Power electronics device, such as a frequency converter, comprising power units (REC1, INU1, INU2, CDC1), a metal frame (31) and a DC bus arrangement in which the power units are connected. The power units may be assembled inside the metal frame (31) wherein the shape of the metal frame is elongated with rectangular cross-sectional shape, consisting of a bottom part (33) and from that essentially vertical oriented side wall parts (32). The DC bus arrangement is arranged on top of the bottom part (33) of the metal frame (31) and separated by an insulator layer (S1) from the metal frame (31). The DC bus arrangement comprises a first DC bus current conductor (DC+) and a second DC bus current conductor (DC-) which are arranged apart from each other. The DC bus current conductors (DC+, DC-) have a flat shape in such a way that their thickness dimension is essentially shorter than their width dimension.
