Inhalt:
Today DC offers far-reaching advantages over AC. Therefore, many devices have been equipped with an internal DC link for many years. In the field of energy supply, the use of DC technology is also growing and is state of the art in offshore, high-voltage, vehicle and data center applications. The spread of industrial open DC grids is currently starting and is completely different due to the requirements: The industrial DC grid is highly dynamic. This means that power varies greatly over time and therefore there is a large amount of capacitance with little damping. The paper describes possibilities of outsourcing DC link capacitors from devices and the resulting influences on the lifetime.
