The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0042] The following describes the programming-based automatic optimization and recommendation method and device for DC converter topology according to an embodiment of the present invention with reference to the accompanying drawings.

[0043] The embodiment of the present invention provides a programming-based method for automatically optimizing and recommending a DC converter topology, so as to automatically recommend an optimal topology according to engineering requirements.

[0044] Figure 1 A schematic flow chart of a method for automatically optimizing and recommending a DC converter topology based on programming provided in an embodiment of the present invention.

[0045] like Figure 1 As shown, the programming-based DC converter topology automatic optimization and recommendation method includes the following steps:

[0046] Step S101, determining the engineering requirements and the device types and device quantities of the DC converter topology diagram required for the engineering, and generating a first table using a DC converter topology diagram construction method based on vertex prime degree, wherein the first table includes a plurality of DC converter topologies.

[0047] In step S101, the determined engineering requirements may include structural requirements, ripple requirements, gain requirements, and requirements for voltage, power, cost and efficiency. Among them, the structural requirements include common ground output, negative voltage output and non-common ground non-negative voltage output requirements. The ripple requirements include low input ripple, low output ripple, low input low output ripple and non-low ripple requirements. The gain requirements include boost requirements, buck requirements and buck-boost requirements. The requirements for voltage, power, cost and efficiency can be requirements for input voltage, output voltage, output power, low cost and high efficiency.

[0048] In step S101, the device types of the DC converter topology diagram required for the project may include switch tubes, diodes, inductors, capacitors, input ports, and output ports. The number of devices corresponding to the six device types is 2, 2, 2, 1, 1, 1.

[0049] In step S101, according to the determined engineering requirements, the device types and device quantities of the DC converter topology diagram required for the project, a DC converter topology diagram construction method based on vertex prime degree is used to obtain a variety of DC converter topology diagrams (referred to as topology diagrams), and all the DC converter topology diagrams obtained form a first table.

[0050] Step S102: structurally classify the DC converter topology diagrams in the first table using a preset first condition to generate a second table.

[0051] In step S102, the first condition is preset as a classification condition for different structural requirements of the topology diagram. Based on step S101, it can be known that the structural requirements may include common ground output, negative pressure output, and non-common ground non-negative pressure output requirements. That is, the first condition is preset to include three classification conditions: classifying the topology diagram as a common ground output topology diagram, classifying the topology diagram as a negative pressure output topology diagram, and classifying the topology diagram as a non-common ground non-negative pressure output topology diagram.

[0052] Figure 2 This is a flow chart of classification using a preset first condition provided by an embodiment of the present invention. Figure 2 As shown, the process of structurally classifying the DC converter topology diagrams in the first table using the preset first condition includes:

[0053] The topology diagrams are classified into common ground output topology diagrams: the topology diagram in which the negative end of the input port is connected to the negative end of the output port;

[0054] The topology diagram is classified into negative voltage output topology diagram: the topology diagram in which the negative end of the input port is connected to the positive end of the output port;

[0055] Classify the topology diagrams into non-common ground and non-negative pressure output topology diagrams: topology diagrams that do not meet the above two topology classification standards;

[0056] The second table is obtained by performing the three classification processes on the DC converter topology diagram in the first table.

[0057] Step S103, using a preset second condition to perform ripple classification on the DC converter topology diagrams in the first table to generate a third table.

[0058] In step S103, the second condition is preset as a classification condition for different ripple requirements of the topology diagram. Based on step S101, it can be known that the ripple requirement may include low input ripple, low output ripple, low input and low output ripple, and non-low ripple requirements. That is, the second condition is preset to include classifying the topology diagram into a low input ripple topology diagram, classifying the topology diagram into a low output ripple topology diagram, classifying the topology diagram into a low input and low output ripple topology diagram, and classifying the topology diagram into a non-low ripple topology diagram.

[0059] Figure 3 This is a flow chart of classification using a preset second condition provided by an embodiment of the present invention. Figure 3 As shown, the process of classifying the ripple of the DC converter topology diagram in the first table by using the preset second condition includes:

[0060] The topology diagram is classified into low input ripple topology diagram: the positive or negative end of the input port of the topology diagram is connected to either end of the inductor;

[0061] The topology diagram is classified into low output ripple topology diagram: the positive or negative end of the output port of the topology diagram is connected to either end of the inductor;

[0062] Classify the topology diagram into low input and low output ripple topology diagrams: meet the above two topology diagram classification standards;

[0063] Classify the topology into non-low ripple topology: topology that does not meet the above three topology classification standards;

[0064] The third table is obtained by performing the four classification processes on the DC converter topology diagrams in the first table.

[0065] Step S104, performing gain classification on the DC converter topologies in the first table using a preset third condition to generate a fourth table.

[0066] In step S104, the third condition is preset as a classification condition for different gain requirements of the topology diagram. Based on step S101, it can be known that the gain requirement may include a boost requirement, a buck requirement, and a buck-boost requirement. That is, the third condition is preset to include classifying the topology diagram as a boost topology diagram, classifying the topology diagram as a buck topology diagram, and classifying the topology diagram as a buck-boost topology diagram.

[0067] Figure 4 This is a flow chart of classification using a preset third condition provided by an embodiment of the present invention. Figure 4 As shown, the process of performing gain classification on the DC converter topology diagram in the first table using the preset third condition includes:

[0068] The topologies are classified into boost topologies: topologies whose gain is always greater than 1 for any duty cycle;

[0069] The topologies are classified into buck topologies: topologies whose gain is always less than 1 for any duty cycle;

[0070] Classify the topology diagrams into buck-boost topology diagrams: the topology diagrams that do not meet the above two topology classification standards;

[0071] The fourth table is obtained by performing the three classification processes on the DC converter topology diagrams in the first table.

[0072] Step S105 , screening the DC converter topology diagram in the first table by using the engineering requirements, the second table, the third table and the fourth table to generate a fifth table.

[0073] In step S105, the DC converter topology diagrams in the first table are screened using the determined engineering requirements, the second table, the third table and the fourth table to screen out topology diagrams that meet the engineering requirements. These topology diagrams that meet the engineering requirements form a fifth table.

[0074] Step S106, using the preset fourth condition to screen the DC converter topology diagrams in the fifth table to generate a sixth table, which includes the optimal DC converter topology diagrams.

[0075] In step S106, the fourth condition is preset as a classification condition for topological diagrams with different cost efficiencies. The DC converter topological diagrams in the fifth table are screened using the preset fourth condition to screen out the best topological diagram that meets the engineering requirements.

[0076] Figure 5 This is a flow chart of classification using the preset fourth condition provided by an embodiment of the present invention. Figure 5 As shown, the process of screening the DC converter topology diagrams in the fifth table by using the preset fourth condition includes:

[0077] The topological maps in the fifth table are screened for low-cost and high-efficiency topological maps to obtain the sixth table. The screening principle is as follows: when the efficiency is greater than or equal to 99%, the low-cost topological map is given priority; when the efficiency is less than 99%, the high-efficiency topological map is given priority.

[0078] The following is a verification of a method for automatically optimizing and recommending a DC converter topology based on programming according to an embodiment of the present invention in conjunction with a specific embodiment, which specifically includes:

[0079] Step 1): The engineering requirements are determined as input voltage 48V, output voltage 400V, output power 500W, common ground output, low input ripple, boost, low cost and high efficiency; the device types of the DC converter topology diagram are switch tube S, diode D, inductor L, capacitor C, input port V dc1 , output port V R1 , as shown in Table 1, the corresponding number of devices is 2, 2, 2, 1, 1, 1.

[0085] Step 5): Use the preset third condition to perform gain classification on the topological graphs in the first table to obtain a fourth table.

[0086] Step 6): Use the engineering requirements, the second table, the third table, and the fourth table to filter the topology diagram in the first table to obtain the fifth table.

[0087] Step 7): Use the preset fourth condition to filter the topological graphs in the fifth table to obtain the sixth table.
