摘要： A circuit arrangement for providing electrical power for at least one DC load from at least one alternating current source having a primary DC intermediate voltage circuit. The primary DC intermediate voltage circuit is supplied with electrical power of the alternating current source via two rectifiers connected in series such that a centre point tap is provided, means for limiting the DC output voltage of the associated rectifier are provided between the centre point tap of the primary DC intermediate voltage circuit and at least one DC potential of the primary DC intermediate voltage circuit, which can limit the DC output voltage of at least one of the rectifiers connected in series in the event of a fault state in the DC load, in the secondary DC intermediate voltage circuit and/or in at least one of the DC/DC converters.

摘要： The invention relates to a method of controlling the on-time of a plurality of energy modules of an energy storage. The energy storage comprising a plurality of series connected energy modules forming an energy module string. A string controller is controlling which of the individual energy modules that is part of a current path through the energy module string, by control of the status of a plurality of switches. The string controller is controlling the frequency of the energy module string voltage according to an electric system reference related to a system to which the energy storage is connected. And wherein the string controller is controlling the switches of the individual energy modules so that each of the individual energy modules that are required to be included in the current path to establish the energy modules string voltage are included in the current path for at least a minimum on-time.

摘要： The application relates to an energy storage including a plurality of energy modules arranged in one or more energy module strings. A string controller is configured for controlling a current path through the energy module strings by controlling the status of a plurality of semiconductor switches. A first end of a current path is electrically connectable to a first electric system of a first electric bus via a first bus switch and to a second electric system of a second electric bus via a second bus switch. A second end of the current path is electrically connectable to a first reference potential being the same as the reference potential of the electric systems connected to the first end of the current path. An energy storage controller is configured for controlling the status of the first bus switch and of the second bus switch in dependency of the received power status.
