Abstract
An apparatus includes a DC-link, a voltage converter, a bus voltage controller, and a supervisory controller. The voltage converter is configured to convert a first DC voltage into a second DC voltage based on a command signal and based on an adjustment signal and to supply the second DC voltage to the DC-link. The bus voltage controller is configured to iterate calculation of the adjustment signal to communicate each iterated calculation of the adjustment signal to the voltage converter. The supervisory controller is configured to iterate calculation of the command signal and to communicate each iterated calculation of the command signal to the voltage converter and to the bus voltage controller. A frequency of the bus voltage controller to communicate each iterated calculation of the adjustment signal is higher than a frequency of the supervisory controller to communicate each iterated calculation of the command signal.
