摘要： The invention relates to a drive system for a facility having an alternating-current isolated network, in particular for a ship or an offshore platform, comprising a three-phase drive machine (8), which can be operated both as a motor and as a generator, and comprising a converter (2) having a direct-current intermediate circuit (5) having an intermediate circuit voltage (Uz). The invention aims to provide a way of avoiding undesired and/or impermissible voltage and/or frequency increases in the alternating-current isolated network. For this purpose, the drive system comprises according to the invention an energy absorbing device (20) arranged in the intermediate circuit (5), which energy absorbing device comprises at least one energy absorber (21), which preferably comprises at least one electrical resistor, for absorbing at least a part of the electrical energy that the three-phase drive machine (8) generates in generator operation and outputs to the intermediate circuit (5) by means of the motor-side current converter (4) of the converter (2). The energy absorber (21) can be activated by the energy absorbing device (20) according to the polarity of the intermediate circuit voltage (Uz). The energy absorbing device (20) is preferably variable regarding an absorption of electrical braking power of the three-phase drive machine (8).

A switching network (28) includes a plurality of transistors (29) and diodes (131) connected to the coils (30). A current source inverter is provided by a switching network, a pair of inductors (26) positioned on power rails, and commutating capacitors (32). The current source inverter and the coils (30) are all positioned within said housing (22). Power architecture for a vehicle has a source of DC power, which communicates with machines through integrated motor drives. The motor drives include at least three coils positioned adjacent to the rotors for a motor associated with the integrated motor drive. A storage switching network is positioned downstream of the coils, with the storage switching network to be closed to allow power from the coils to drive the rotor, or to be opened to allow power to pass to a local storage component.

摘要： An apparatus includes a DC-link (26), a voltage converter (14), a bus voltage controller (36), and a supervisory controller (12). The voltage converter (14) 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 (26). The bus voltage controller (36) is configured to iterate calculation of the adjustment signal to communicate each iterated calculation of the adjustment signal to the voltage converter (14). The supervisory controller (12) is configured to iterate calculation of the command signal and to communicate each iterated calculation of the command signal to the voltage converter (14) and to the bus voltage controller (36). A frequency of the bus voltage controller (36) to communicate each iterated calculation of the adjustment signal is higher than a frequency of the supervisory controller (12) to communicate each iterated calculation of the command signal.
