VOLTAGE RANGE DETERMINATION FOR AN INTERMEDIATE BUS ARCHITECTURE POWER SUPPLY CONTROLLER

摘要

The invention relates to a range determining device for a voltage controller of an intermediate bus voltage (VIB) in an intermediate bus architecture power system, an intermediate bus architecture power system as well as to a method, computer program and computer program product of providing a range within which a controlled intermediate bus voltage in an intermediate bus architecture power system is allowed to vary. The range determining device obtains a range (R3) for the controlled intermediate bus voltage, which range has been determined based on statistical data corresponding to a current time interval of the control, and provides the range to the voltage controller for the voltage controller to control the intermediate bus voltage (VIB) within the determined range in a current time interval.
