The present invention relates to a device and method for uninterruptible power supply. An ordinary AC voltage source, p, supplies an AC voltage to a converter, L, which conveys a DC voltage to voltage converters, S. The voltage converters, S, adapt the received DC voltage to one for the users adapted DC voltage, or conversion to one by the users adapted AC voltage. In connection to the converter, A, a DC voltage is arranged adapted to bridge a time corresponding to the connection and start up time for a standby electrical power unit, G. The suggested solution makes possible that standby electric power is offered without interruption. |
