Definitions
- the invention relates to the field of capacitive components for electric power devices, and in particular to a composite capacitance used as a DC-link capacitance in an electric power frequency converter.
- a state-of-the-art frequency converter as depicted in Fig.8 comprises typically a rectifier converting alternating current (AC) to direct current (DC), an inverter converting direct current (DC) to alternating current (AC), as well as a DC link connecting the rectifier and inverter.
- the DC link comprises a capacitive component acting as energy storage and filter for the DC-link voltage.
- a conventional capacitive component used in a power frequency converter or other power device comprises one or several capacitors which are mounted directly on a main circuit board of the power frequency converter and tend to occupy a large area on the main circuit board.
- the supply chain management is an important issue.
- replacement of a failed capacitor on the main circuit board might be time-consuming and onerous.
- US 6215278 discloses a single type of box-like capacitor modules with improved packaging density and housing series-connected capacitor cells, to be arranged in capacitor banks with a heat-dissipater mounted on an end surface of the modules located on the outside of the bank.
- Flexible printed circuits positioned on any surface of the module include interconnects for monitoring signals.
- the folded capacitor cells are not rigidly mounted on a support board but tightly squeezed between two pressure plates at opposite ends of the stacked cells.
- US 4912597 discloses a capacitor bank with ten base capacitors arranged next to each other in two parallel rows, the capacitors of each row being electrically connected to a respective one of two parallel dielectric Printed Circuit Boards (PCBs).
- the two PCBs are identical and comprise copper claddings and dielectric stripes configured and arranged in exactly the same manner. Accordingly, the two modules consisting each of a PCB and a row of five capacitors are not physically distinguishable.
- a composite capacitance which comprises a plurality of physically distinguishable capacitor modules electrically connected with each other.
- Each of the capacitor modules comprises a number of base capacitors mounted on and electrically connected to a module-specific Printed Circuit Board (PCB), wherein all the base capacitors from the plurality of modules are of a single type.
- PCB Printed Circuit Board
- physically distinguishable capacitor modules exhibit distinct mechanical and/or electrical properties. That is, two capacitor modules out of the plurality of physically distinguishable capacitor modules may have a different number of base capacitors. Or the PCBs of the two modules may distinguish in shape, size, thickness, or topography. Distinguishable modules may further differ in internal wiring, printed circuits, or electrical interconnection of the base capacitors mounted thereon.
- the spatial flexibility gained by the use of a plurality of electrically interconnected capacitor modules is advantageous in those electrical power devices where the volume available for the capacitive component inside the device might be limited or otherwise constrained in at least one direction.
- At least one of the capacitor modules is mounted on and electrically connected to a support board with a central axis of all its cylindrical base capacitors arranged substantially parallel to the surface of the support board.
- the base capacitors of one module are arranged on one side or on both sides of the module- specific PCB.
- the base capacitors are electrically connected through printed circuits on or within the module-specific PCB in order to constitute the total capacitance of the capacitor module.
- the modules comprise additional components such as voltage dividing circuits, high frequency capacitors, charging and discharging circuits or capacitor diagnostics circuits arranged on the module-specific PCB.
- the additional components contribute to a more complete functionality of the composite capacitance, by simplifying a connection with other modules, extending a high frequency bandwidth and detecting the performance of the module, respectively.
- the module- specific PCB may comprise holes permitting cooling air to pass through and establish a flow of cooling air in a direction parallel to the central axis of the base capacitors.
- the holes are provided in an area overlapping with the open area between the base capacitors where the PCB is visible when viewing the module in said direction.
- the present invention also relates to a use of the above mentioned composite capacitance as a DC-Link capacitance in a space-constrained low voltage or medium voltage power frequency converter.
- Fig.1 shows a composite capacitance in accordance with the present invention
- Fig.2, 3 and 4 depict three capacitor modules for a composite capacitance
- Fig.5 and 6 show two schematic cross sections of a capacitor module
- Fig.7 depicts five capacitor modules based on five different types of base capacitors;
- Fig.8 shows a schematic diagram of a prior art power frequency converter.
- Preferred Embodiments of the Invention Fig.1 depicts a composite capacitance with a plurality of capacitor modules (32, 33, 34 and 35) each comprising a module-specific PCB (Printed Circuit Board) and being mounted on a support board (31 ).
- the plurality of capacitor modules are electrically connected to each other in serial and/or parallel connection by means of suitable connecting circuits on the support board.
- the capacitor modules and the support board together form a composite capacitance or capacitive component to be used in an electrical power device such as power frequency converter.
- Each capacitor module comprises one single module-specific PCB, and all the cylindrical base capacitors (36) arranged on a single PCB are part of the same board-specific module.
- the capacitor modules are mounted on the support board in a manner such that a central axis of all the cylindrical base capacitors is arranged substantially parallel to the surface of the support board.
- the number of mounted modules, their mutual arrangement, and the size of each module can be selected arbitrarily, such that the resulting composite capacitance may have an overall shape that departs from a standard rectangular volume.
- the arrangement of capacitor modules depicted in Fig.1 gives rise to a wedge-shaped overall volume.
- the total capacitance of is made up by the totality of modules mounted on the support board, the number of base capacitors on each module and the specifics of the electrical base capacitor connection.
- At least two out of the plurality of capacitor modules are physically distinguishable in terms of, for example, mechanical properties or electrical properties. That is, the PCBs of these distinct modules may distinguish in shape, size, thickness, or topography. Distinct modules may also have a different number of base capacitors and/or distinguish in the internal wiring or electrical interconnection of the base capacitors. Hence the total capacitance of two distinct modules may be different or the same.
- the structure and configuration of the composite capacitance is very flexible and may be optimized to adapt to or fill any available space in the electrical power device. Compared to a conventional capacitive component which uses only a single-storey volume closest to PCB surface, the proposed composite capacitance can, by stacking base capacitors, occupy additional parts of the internal space above the PCB surface.
- the capacitor modules (32, 33, 34, 35) in Fig.1 show three to six base capacitors (36) arranged next to each other in a direction perpendicular to the support board (31 ).
- the four capacitor modules are arranged parallel to each other.
- two or more PCB modules may alternatively form an arbitrary angle at their intersection. Therefore, the proposed composite capacitance enables an optimized usage of the available three dimensional spaces within the electrical power device.
- the modules can be mounted on the support board through various connecting means. By selecting the connecting means appropriately, the modules can be easily and repeatedly mounted and removed. That is, in case a single capacitor module does not function properly, the latter can be replaced by a spare one in a straightforward manner. Moreover, if during operation a different total capacitance should be required for the power device, modules can be added to or removed from the support board accordingly. Under the following design aspects, it is preferable to build the capacitor module based on a large number of base capacitors with small capacitance rather than a few capacitors with large capacitance. By doing so, if only one or few base capacitors fail while the other base capacitors of the capacitor module continue to work properly the total capacitance is only slightly diminished. The reliability of the proposed module is thus improved.
- the total equivalent stray inductance of the capacitor module becomes very low, which could result in advantageously stable switching behavior.
- the total heat generated by a large number of small capacitors is typically less than the heat generated by a few large capacitors of the same capacitance.
- the total capacitance of the module being constituted by a great number of identical base capacitors gives rise to an appreciable economy of scale and a simplified supply chain management.
- a first individual capacitor module is shown.
- Many base capacitors (12) of a single type are mounted on a module-specific Printed Circuit Board PCB (1 1 ).
- the type and capacitance of the base capacitors can be arbitrarily selected according to the requirements of the intended application.
- the base capacitors (12) are mounted on both sides of the PCB (1 1 ).
- the base capacitors (12) may be mounted on a single side of the PCB only. Considering the dimensions of the PCB and the footprint of each base capacitor, as many base capacitors as possible are mounted on the PCB. That is, by arranging base capacitors side by side in a square or even in a triangular close-packed lattice, the area of PCB surface occupied by capacitors is substantially identical with the overall surface area of the PCB.
- Fig.3 depicts a capacitor module with several electronic components (21 ) in addition to the base capacitors arranged on the PCB. Additional electronic components can be easily integrated with the capacitor module in order to improve the performance or add desired functionality.
- the additional components may include a voltage dividing circuit, a high frequency capacitor and a capacitor diagnostics circuit.
- dedicated high frequency capacitors connected in parallel to the main capacitors can be integrated in order to improve the frequency bandwidth of the module; and a diagnostic sensor may be integrated in order to detect and improve the signaling performance of the capacitor module.
- a voltage dividing circuit e.g. parallel resistors
- Further additional functions may be added through integrating capacitor charging and discharging circuits.
- the PCB-based capacitor modules can be equipped with various connectors for any intended purpose or application. While any commercially available type of connectors can be used as a connecting means for the capacitor module, Fig.2 and Fig.3 depict a specially designed extra-wide low impedance connector (13).
- the connector (13) makes it possible to easily and reversibly attach and detach the capacitor module to/from the support board.
- the PCBs shown in Fig.2 and 3 are of square shape, the PCBs can be designed to have any other shape as well. For example, a triangular or a circular shaped PCB is also possible and may even be preferable in view of the internal space of the electrical power device that it will be used in.
- Fig.4 depicts a plurality of air convection holes (22) provided on the PCB (1 1 ) of the capacitor module.
- the air convection holes allow cooling air to flow in a direction parallel to the base capacitors (12) mounted on the PCB.
- the holes are arranged on the PCB in such a manner that the holes are at least partially visible when viewing the PCB in a direction of the base capacitors (12), i.e. the holes basically coincide with the interstices between the base capacitors.
- Fig.5 and Fig.6 show two out of countless possible ways of interconnecting the base capacitors on the PCB.
- Fig.5 depicts a cross section of a module with all the base capacitors (41 ) being parallel connected and mounted on one side of the PCB.
- the PCB comprises three layers, a plus conducting layer (44), a minus conducting layer (46) and an insulation layer (45) sandwiched between above two conducting layers. Plus and minus pins (42, 43) of the base capacitors are connected with plus and minus conducting layers (44, 46) at pin-to-PCB connecting contacts (47, 49).
- the plus pin 42 connects with plus conducting layer (44) on contact (49), and the minus pin traverses the plus conducting layer (44) via an opening or recess (48) provided in the plus conducting layer, and is connected with minus conducting layer (46) at the contact point (47) at the opposite side of the PCB.
- the base capacitors can be mounted on both sides of the PCB and electrically connected in parallel by means of the two conducting layers.
- Fig.6 a cross section of a module is shown, wherein, the capacitors are two-by- two series connected and mounted on one side of the PCB. Contrary to Fig.5, the upper conducting layer is divided into a first upper conducting layer (610) and a second upper conducting layer (64), which both serve as serial contacts to the abovementioned connectors or to further neighboring pairs of base capacitors.
- Fig.6 all capacitors (61 ) (C1 to C4) are connected with bottom conducting layer (61 1 ). However, both of the capacitors C1 and C2 are connected with the first upper conducting layer (610), and both of the capacitors C3 and C4 are connected with the second upper conducting layer (64). Therefore, the base capacitors C1 and C2 are connected in parallel as a first group; and the base capacitors C3 and C4 are connected in parallel as a second group. The first capacitor group (C1 , C2) is connected with the second capacitor group (C3, C4) in series.
- Fig.7 depicts five capacitor modules (71 , 72, 73, 74 and 75) of substantially identical total capacitance and based on five different types of base capacitors. The geometrical and electrical arrangement of the base capacitors gives rise to the physical properties as follows.
- the first module A (71 ) comprises 4 base capacitors, and its total surface area is 252,675 mm 2 ; its total volume is 7,320,404 mm 3 ; its total impedance Zmax (10kHz, 2O 0 C) is 5 mOhm; and its total ripple current capability I_AC max (100Hz, 85 0 C) is 90.2A.
- the second module B (72) comprises 6 base capacitors, and its total surface area is 247,815 mm 2 ; its total volume is 7,179,627 mm 3 ; its total Zmax (10kHz, 20 0 C) is 4.67 mOhm; its total I_AC max (100Hz, 85 0 C) is 97.8A.
- -the third module C (73) comprises 33 base capacitors, and its total surface area is 431 ,624 mm 2 ; its total volume is 7,090,664 mm 3 ; its total Zmax (10kHz, 2O 0 C) is 4.36 mOhm; its total I_AC max (100Hz, 85 0 C) is 151 .8 A.
- -the fourth module D (74) comprises 50 base capacitors, and its total surface area is 653,975 mm 2 ; its total volume is 10,743,430 mm 3 ; its total Zmax (1 OkHz, 20 0 C) is 4.88 mOhm; and its total I_AC max (100Hz, 85 0 C) is 170A.
- the fifth module E (75) comprises 270 base capacitors, and its total surface area is 932,877 mm 2 ; its total volume is 6,534,000 mm 3 ; its total Zmax (1 OkHz, 20 0 C) is 4.3 mOhm; its total I_AC max (100Hz, 85 0 C) is 126.9 A.
