Description

Technical Field

[0001] This invention relates to the field of power components and converters, and more specifically to an integrated power component and converter. Background Technology

[0002] Converters are widely used in power systems, rail transportation, military industry, petroleum machinery, new energy vehicles, wind power generation, solar photovoltaic and other fields. They can realize unidirectional or bidirectional conversion of electrical energy and have rectification and inversion functions. Among them, the NPC (Neutral Point Clamp) or ANPC (Active Neutral Point Clamp) three-level topology can use IGBT devices with low blocking voltage to increase the DC bus voltage, thereby increasing the AC output voltage and expanding the system power level. Therefore, it has been widely used in converters.

[0003] The main component of a converter is the power module, which primarily consists of a capacitor busbar and several switching transistors, typically IGBT modules. The rapid switching of these IGBT modules enables AC-DC conversion. However, the relatively high price of existing IGBT modules increases the overall cost of the converter. Summary of the Invention

[0004] The purpose of this invention is to overcome the aforementioned defects or problems in the prior art and to provide an integrated power component and converter that can reduce the overall cost of the converter when the price of IGBT modules is high.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Technical Solution 1: An integrated power component comprising: a circuit board defining a plurality of switch wiring areas arranged along a first direction; each switch wiring area having two first switch modules and two second switch modules, the first switch modules comprising a first number of switch modules connected in parallel, and the second switch modules comprising a second number of switch modules connected in parallel; each switch module comprising a plurality of single transistors, each single transistor cooperating with each other to achieve a controllable switching function and forming an input terminal, an output terminal, and a driving terminal of the switch module; the single transistors being diodes, transistors, or MOSFETs; within each switch wiring area, two second switch modules are arranged adjacent to each other, and two first switch modules are respectively located on both sides of the two second switch modules.

[0007] Technical solution two is based on technical solution one: the input, output and drive terminals of each switch module are arranged in parallel.

[0008] Technical solution three is based on technical solution two: within each switch wiring area, each switch module in the two first switch modules is arranged sequentially along the second direction, which is perpendicular to the first direction.

[0009] Technical solution four is based on technical solution three: within each switch wiring area, the input terminals, output terminals, and drive terminals of each switch module belonging to different first switch modules are oriented in opposite directions in a first direction.

[0010] Technical solution five is based on technical solution four: within each switch wiring area, two second switch modules are arranged adjacent to each other in the second direction.

[0011] Technical solution six is ​​based on technical solution five: In each switch wiring area, in the two second switch modules, some switch modules are arranged sequentially along the first direction, and the remaining switch modules are located between the switch modules arranged sequentially along the first direction in the two second switch modules.

[0012] Technical solution seven is based on technical solution four: within each switch wiring area, two second switch modules are arranged adjacent to each other in the first direction.

[0013] Technical solution eight is based on technical solution seven: within each switch wiring area, each switch module in the two second switch modules is arranged sequentially along the second direction.

[0014] Technical solution nine is based on technical solution eight: within each switch wiring area, the input terminals, output terminals, and drive terminals of each switch module belonging to different second switch modules are oriented opposite to each other in the first direction.

[0015] Technical Solution 10: A converter comprising an integrated power component as described in any one of Technical Solutions 1 to 9.

[0016] As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following beneficial effects:

[0017] In technical solution one, several switch wiring areas are defined on the circuit board. These switch wiring areas can be used to set switch modules. The switch modules include a first switch module and a second switch module. Both of them include a certain number of switch modules. The number of switch modules in the two can be the same or different. Each switch wiring area forms a commutation circuit through the cooperation of multiple switch modules to realize the power conversion function of the power component. Each switching module consists of several individual transistors, functioning as an IGBT module. The combination of these semiconductor transistors enables the controllable switching function of the switching module. Each switching module forms its input, output, and drive terminals through the collector, emitter, and gate of the corresponding semiconductor transistor, facilitating external wiring. Furthermore, using individual semiconductor transistors to form the switching module is less expensive than using individual switching modules, effectively reducing the cost of the power component. The use of individual semiconductor transistors also provides a larger heat dissipation area, improving the heat dissipation efficiency of the power component. Additionally, the increased number of circuit connection points allows for easier fault location in case of a malfunction, and repairs can be completed simply by replacing the faulty semiconductor transistor, resulting in higher maintenance efficiency. Moreover, a single switching module includes multiple switching modules connected in parallel, reducing the stress on each module and its internal semiconductor transistors, making them less prone to damage. However, combining individual semiconductor components to form a switching module results in a high stray inductance in the power component's commutation circuit. To address this, in this technical solution, all switching modules within each switching wiring area are divided into four parts: a first switching module and a second switching module. Two second switching modules are arranged adjacent to each other, while the other two first switching modules are located on either side of the two second switching modules. This minimizes the distance between the switching modules, shortens the length of the commutation circuit between the four switching modules, and reduces the overall stray inductance of the power component, enabling the power component to meet the stray inductance requirements during use.

[0018] In technical solution two, the input, output and drive terminals of each switch module are arranged in parallel, which facilitates the etching and connection of wiring circuits on the circuit board. The circuit layout of each switch module is more regular and also facilitates the integrated setup of the corresponding switch modules.

[0019] In technical solution three, each switch module in the first switch module is arranged sequentially along a second direction perpendicular to the first direction. When the first direction is the horizontal direction along the circuit board, the first switch module is arranged vertically along the circuit board. This arrangement facilitates the arrangement of other electrical components on the circuit board, such as capacitor busbars, and the two first switch modules can define a space between them, thus conveniently sandwiching the two second switch modules in the middle.

[0020] In technical solution four, the input, output, and drive terminals of the corresponding switch modules in the two first switch modules are oriented opposite to each other in the first direction. This is because the space between the two first switch modules needs to accommodate the second switch module, and the second switch module also needs to be wired externally. If the terminals of the first switch modules are oriented towards each other in the first direction, too many wires will be gathered in the middle of the switch wiring area. Therefore, with the above arrangement, the wiring of the first switch module can be arranged on the side of the switch wiring area, and the middle of the switch wiring area can be left for the second switch module to wire, making the wiring layout clearer and simpler.

[0021] In technical solution five, the two second switch modules are arranged adjacent to each other in the second direction. This arrangement can reduce the distance between the two second switch modules, thereby shortening the overall converter circuit.

[0022] In technical solution six, some switch modules in two adjacent second switch modules arranged in the second direction are arranged sequentially along the first direction, and the remaining switch modules can be located between these switch modules arranged along the first direction. Of course, the remaining switch modules should be the same number or fewer as the switch modules arranged along the first direction, so that the arrangement of each switch module in the second switch module can be balanced. By setting it in this way, the switch modules in the second switch module can be more concentrated, further shortening the commutation loop and reducing stray inductance.

[0023] In technical solutions seven and eight, two second switch modules are arranged adjacent to each other in the first direction, in conjunction with two first switch modules arranged in the first direction. Each switch module in the four switch modules is arranged vertically. This layout forms a shorter commutation loop between the four switch modules, which can effectively reduce the stray inductance of the circuit.

[0024] In technical solution nine, the wiring terminals of each switch module belonging to the second switch module are oriented opposite to each other in the first direction, similar to technical solution four, which can make the wiring layout clearer and simpler.

[0025] In technical solution ten, a converter is provided. This converter, by adopting the aforementioned integrated power components, can effectively reduce manufacturing costs and has low stray inductance, thus meeting the application requirements. Attached Figure Description

[0041] Example

[0042] Reference Figure 1 This embodiment provides an integrated power component, which includes a circuit board 1 and electrical components disposed on the circuit board 1.

[0043] Specifically, the integrated power component provided in this embodiment is used to realize the diagram, Figure 3 or Figure 4 The circuits shown are both inverter circuits used to convert DC input to AC output. Figure 2 It is a T-type three-level topology circuit. Figure 3 It is a type I three-level topology circuit. Figure 4This is an ANPC type three-level topology circuit. (Refer to...) Figure 2 and Figure 3 It can be seen that both inverter circuits include four switching units, each of which includes a switching transistor T and a diode D. Figure 2 and Figure 3 In this context, the serial number of the corresponding switching unit is indicated by the designation of the switching transistor or diode. For example, the serial number of the switching unit formed by T1 and D1 is 1, and so on. (Refer to...) Figure 4 ,and Figure 2 and Figure 3 The difference lies in the fact that... Figure 2 and Figure 3 The two individually used diodes D in the circuit are replaced with a complete switching unit. In use, the switching on and off of each switching transistor is controlled by a drive control board to achieve various forms of AC output. This application method is a conventional technique in this technical field and will not be elaborated upon here. Typically, this switching transistor can be implemented using an IGBT module; however, IGBT modules are expensive, and their large-scale use would lead to excessively high manufacturing costs for this integrated power component.

[0044] Therefore, the integrated power component provided in this embodiment adopts the following solution:

[0045] The circuit board 1 of the integrated power component defines a plurality of switch wiring areas 2 arranged along a first direction. Each switch wiring area 2 is provided with two first switch modules 3 and two second switch modules 4. The first switch module 3 includes a first number of switch modules 5 connected in parallel, and the second switch module 4 includes a second number of switch modules 5 connected in parallel. Furthermore, within each switch wiring area 2, the two second switch modules 4 are arranged adjacent to each other, and the two first switch modules 3 are respectively located on both sides of the two second switch modules 4.

[0046] The switching module 5 includes several individual transistors, which cooperate to achieve a controllable switching function and form the input terminal 6, output terminal 7, and drive terminal 8 of the switching module 5. The individual transistors are diodes, transistors, or MOSFETs. It should be noted that since these individual transistors need to cooperate to form the controllable switching module 5, at least one of these individual transistors should be able to be driven and controlled by sending a signal, thus enabling the switching module 5 to form the input terminal 6, output terminal 7, and drive terminal 8.

[0047] Specifically, refer to Figure 1 In addition to the circuit board 1, the integrated power component provided in this embodiment also includes multiple switching modules and capacitor modules 9. The capacitor modules 9 are... Figure 2 or Figure 3 The capacitors C1, C2, C3, or C4 in the circuit shown represent the switching module. Figure 2, Figure 3 or Figure 4 A switching unit in the circuit shown, a switch wiring area 2 includes a set of Figure 2 , Figure 3 or Figure 4 The circuit shown includes three sets of circuits on the circuit board 1 for inverting three-phase electricity. These three switch wiring areas 2 are arranged along a first direction, which is a transverse direction in this embodiment.

[0048] The circuit board 1 is a conventional printed circuit board, and its substrate material can be glass fiber reinforced epoxy resin to improve the structural strength of the circuit board 1. A metal layer is covered on the surface of the circuit board 1, and circuit patterns can be formed on the metal layer through chemical etching or other methods to connect the electrical components thereon. Through the circuit board 1, the electrical components in the integrated power component can be supported and connected through the circuit patterns on the circuit board 1. Therefore, the aforementioned switching module can be reliably installed, connected, and fixed to form a complete circuit system. In addition, the circuit board 1 can be a single-layer structure or a multi-layer structure. A multi-layer circuit board 1 can accommodate more circuits and arrange components more efficiently.

[0049] Each switch module includes multiple switch modules 5, each independently possessing a corresponding switching and conductive function. The parallel connection of multiple switch modules 5 enhances the stress resistance of the entire switch module. (Refer to...) Figure 5 Each switching module 5 includes a transistor, a MOSFET, and a diode. The drain of the MOSFET is connected in parallel to the base of the transistor and the cathode of the diode, and the source of the MOSFET is connected to the emitter of the transistor and the anode of the diode. Diode D1 serves as a freewheeling diode, providing a path for current to continue flowing when the circuit from the transistor to the MOSFET is broken in the switching module 5, preventing backflow current from the load inductor in the circuit and thus protecting the entire switching module 5 from damage. After forming the switching module 5 using the aforementioned semiconductor components, the collector and emitter of the transistor are used as the input terminal 6 and output terminal 7 of the switching module 5, while the gate of the MOSFET serves as the driving terminal 8 of the switching module 5. Figure 6 or Figure 7Each switching module 5 has its input terminal 6, output terminal 7, and drive terminal 8 connected to corresponding wiring points via etched circuits on the circuit board 1, facilitating wiring and maintenance. Using these semiconductor components to form IGBT modules results in lower costs compared to directly using IGBT modules, effectively reducing the cost of the power component. Furthermore, using individual semiconductor components provides a larger heat dissipation area for the entire switching module 5 compared to individual IGBT modules, improving the heat dissipation efficiency of the power component. Simultaneously, the increased number of circuit connection points allows for easier identification of the fault location in case of a failure, and repairs can be completed simply by replacing the faulty semiconductor component, resulting in higher maintenance efficiency and reduced repair costs. Of course, in other embodiments, the specific types and connection methods of the individual transistors within the switching module 5 can be adjusted according to actual needs, such as using only diodes and MOSFETs.

[0050] At the same time, refer to Figure 6 When each switch module 5 is mounted on the circuit board 1, its input terminal 6, output terminal 7, and drive terminal 8 are arranged in parallel. Specifically, the main body of the semiconductor device in each switch module 5 can be mounted on the back of the circuit board 1, and the pins of each semiconductor device are inserted into the circuit board 1, forming corresponding solder joints on the front of the circuit board 1. The collector and emitter of the transistor and the gate of the MOSFET form three solder joints for each switch module 5. These three solder joints are arranged in parallel along a specific direction, which can be the arrangement direction of the three semiconductor devices in the switch module 5. Arranging the input terminal 6, output terminal 7, and drive terminal 8 of each switch module 5 in parallel facilitates the etching and connection of the wiring circuit on the circuit board 1, makes the circuit layout of each switch module 5 more regular, and also facilitates the integrated setup of the corresponding switch modules.

[0051] Reference Figure 6 Each switch wiring area 2 includes two first switch modules 3 and two second switch modules 4. Figure 6 In the illustrated embodiment, the first switch module 3 contains four switch modules 5, and the second switch module 4 contains three switch modules 5. Within each switch module, these switch modules 5 are connected in parallel. Furthermore, the two second switch modules 4 are arranged adjacent to each other, with the two first switch modules 3 located on either side of the two second switch modules 4. Also, corresponding to... Figure 2 or Figure 3 The circuit has two switch modules: the first switch module consists of switch units 1 and 4, and the second switch module consists of switch units 2 and 3.

[0052] In this configuration, each switch module 5 in the two first switch modules 3 is arranged sequentially along a second direction, which is perpendicular to the first direction. Simultaneously, within each switch wiring area 2, the input terminals 6, output terminals 7, and drive terminals 8 of the switch modules 5 belonging to different first switch modules 3 are oriented away from each other along the first direction. Furthermore, the second switch modules 4 are arranged adjacent to each other along the second direction, and in the two second switch modules 4, some switch modules 5 are arranged sequentially along the first direction, while the remaining switch modules 5 are located between the switch modules 5 arranged sequentially along the first direction in the two second switch modules 4.

[0053] Specifically, refer to Figure 6 , Figure 6 The general layout of a switch wiring area 2 on the circuit board 1 is shown. Figure 6 In the illustrated embodiment, two first switch modules 3 are located at both ends in a first direction, and two second switch modules 4 are located at both ends in a second direction, with the two second switch modules 4 placed between the two first switch modules 3. Figure 6 Taking the direction shown as an example, the two first switch modules 3 are located on the left and right sides respectively, and the switch modules 5 within these two switch modules are arranged vertically. In the first switch module 3 on the left, the tube portion of the switch module 5 is on the right, and the wiring terminal portion is on the left. Similarly, in the second switch module 4 on the right, the tube portion of the switch module 5 is on the left, and the wiring terminal portion is on the right. This arrangement allows the wiring to the two first switch modules 3 to be placed on the left and right sides of the switch wiring area 2, without encroaching on the central space. At the same time, Figure 6 In this configuration, each of the two second switch modules 4 contains three switch modules 5 arranged in an "L" shape. Taking the upper second switch module 4 as an example, two switch modules 5 are arranged along the first direction, with another switch module 5 located below them. The other second switch module 4 located at the lower side is similar. Similar to the arrangement of the first switch module 3, in the two second switch modules 4, the corresponding terminals of the switch modules 5 arranged along the first direction are also opposite to each other, thus avoiding excessive convergence during wiring. With this arrangement, the wiring of the first switch module 3 can be arranged on the side of the switch wiring area 2, leaving the middle of the switch wiring area 2 for the second switch module 4 to wire. This results in a clearer and simpler wiring layout, while shortening the commutation loop and reducing stray inductance.

[0054] In addition, refer to Figure 6Each of the first switch module 3 and the second switch module 4 is provided with a drive connector 10. The drive connector 10 is disposed on the circuit board 1 and is connected to the drive terminal 8 of each switch module 5 in the switch module it is in through a circuit. An external drive control board can be connected to the drive connector 10 and transmit the pulse signal used to control the switch module 5 to the drive terminal 8 of the switch module 5 through the drive connector 10, thereby realizing the on and off control of the MOS transistor in the switch module 5.

[0055] Reference Figure 7 ,exist Figure 7 In the embodiment shown, the second switch module 4 adopts the same as... Figure 6 The embodiments shown have different layouts. Figure 7 In the first direction, two second switch modules 4 are arranged adjacent to each other, and each switch module 5 in the two second switch modules 4 is arranged sequentially along the second direction. The input terminals 6, output terminals 7 and driving terminals 8 of each switch module 5 belonging to different second switch modules 4 are oriented opposite to each other in the first direction.

[0056] Specifically, refer to Figure 7 The arrangement of the two first switch modules 3 is the same as Figure 6 The layout schemes shown are the same, the difference being that the arrangement of the two second switch modules 4 is also similar to that of the first switch module 3. Each of the two second switch modules 4 includes four switch modules 5, which are arranged along the second direction. In the second switch module 4 located on the left, the pipe fittings of the four switch modules 5 are on the right, and the wiring is on the left. Conversely, in the second switch module 4 located on the right, the pipe fittings of the four switch modules 5 are on the left, and the wiring is on the right. This arrangement ensures that the switch modules 5 of the four switch modules extend vertically and are arranged horizontally during wiring, preventing mutual interference and making wiring and maintenance more convenient.

[0057] The integrated power component provided by this invention defines several switching wiring areas 2 on a circuit board 1. These switching wiring areas 2 can be used to set up switching modules, including a first switching module 3 and a second switching module 4. Both include a certain number of switching modules 5, and the number of switching modules 5 in the two modules can be the same or different. Each switching wiring area 2 forms a commutation circuit through the cooperation of multiple switching modules, realizing the power component's conversion function. A single switching module includes multiple switching modules 5, which are connected in parallel. Each switching module 5 and its internal semiconductor components are subjected to low pressure and are less prone to damage. However, combining individual semiconductor components to form IGBT modules results in a high stray inductance in the power component's commutation circuit. To address this, in this technical solution, within each switch wiring area 2, all switch modules are divided into four parts according to the first switch module 3 and the second switch module 4. The two second switch modules 4 are arranged adjacent to each other, and the other two first switch modules 3 are located on either side of the two second switch modules 4. This minimizes the distance between the switch modules, shortens the length of the commutation circuit between the four switch modules 5, and reduces the overall stray inductance of the power component, enabling the power component to meet the stray inductance requirements during use.

[0058] Furthermore, this invention also provides a converter that includes the integrated power component described above. Typically, the converter may also include a heat sink, which is disposed on the back of the integrated power component and in contact with the pipe portions of each switching module 5, thereby dissipating heat from the switching modules 5, reducing their temperature, and ensuring the normal operation of the integrated power component.

[0059] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this invention, but does not constitute a limitation on the scope of protection of this invention. Modifications, equivalent substitutions, or other improvements to the embodiments of this invention or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this invention or the foregoing embodiments, in conjunction with common knowledge, general technical knowledge, and / or existing technology, should all be included within the scope of protection of this invention.
