The disclosure relates to an electronic fuse system, and to a method for an electronic fuse system. The method comprises determining () if the number of engaged electronic circuit breaker modules () has changed compared to the stored configuration. Upon determining that the number of engaged electronic circuit breaker modules () has changed, determining () if the configuration of the electronic fuse system has changed by means of comparing a stored configuration in the power distribution controller () and a stored configuration in the electronic circuit breaker module (). Upon determining that the configuration of the electronic fuse system has changed, determining () if a stored configuration is available from the bus (). Upon determining () that a stored configuration is available from the bus, fetch () the stored configuration from the bus and start operation of the electronic fuse system according to the fetched configuration. Upon determining () that a stored configuration is not available from the bus, determining () if a stored configuration is available from the connectable external main processor. Upon determining () that a stored configuration is available from the connectable external main processor, fetch () the configuration from the connectable external main processor and start operation of the electronic fuse system according to the fetched configuration. Upon determining () that a stored configuration is not available from the connectable external main processor, start operation of the electronic fuse system according to a default configuration ().

Electronic fuse system and a method therefore

An energy supply device with connection portion for an energy source and an energy consumer. The energy supply device is arranged to feed energy from an energy source to an energy consumer, and also comprises energy storage for supplying a connected energy consumer with energy in the event of an interruption of energy supply. There is also a control unit and sensing portion for sensing an energy flow to and/or from the energy storage portion. The sensing portion is connected to the control unit which detects a power disturbance if there is an energy flow from the energy storage portion during a predefined length of time.

Device and method for power disturbance detection

The present invention relates to a switched power converter system (), comprising at least a first power converter () and a second power converter (). Each power converter () has a corresponding input terminal () and output terminal (), where each power converter () comprises a corresponding switch arrangement (). The system further comprises a control unit () that at least at start-up is connected to each power converter () in the system () and arranged to control each switch arrangement () by means of spread spectrum modulation, such that cross correlation between the conducted or radiated emissions of the switch arrangements () is avoided.

Coordinated power converter system

A system and method for managing processing resources in a communication device having a power unit with distributed processing capability. In one aspect, digital power control processors that are configured to perform power system tasks and signal processing tasks are reconfigured by reallocating the tasks among the processors in order to balance the processing loads.
