Description

Technical Field

[0001] The present application relates to the technical field of electronic loads, and in particular to an output control method, device, system, electronic device, and storage medium. Background Art

[0002] When an electronic load is performing power supply testing, the power generated by the power supply needs to be consumed by the electronic load or fed back to the grid. This gives rise to two types of electronic loads: dissipative electronic loads and regenerative electronic loads. Currently, most electronic loads on the market use dissipative electronic loads. Dissipative electronic loads convert electrical energy into thermal energy through power tubes, which are then transferred to a heat sink through the power tubes and dissipated through air or water cooling. Regenerative electronic loads use DC-AC converters to convert most of the DC power into AC power and feed it back to the grid, achieving the recycling of local DC and AC power and significantly saving electricity consumption. A very small portion of the energy lost by regenerative electronic loads is converted into heat and transferred to the surrounding environment through air cooling.

[0003] With the development of AI technology, the requirements for server power supply power, current, and response speed are becoming increasingly stringent. Therefore, high-power battery testing requires extremely high test power and extremely fast dynamic response. Using a regenerative electronic load for testing, the boost inductor is limited by the physical law that inductor current cannot change suddenly, making it impossible to achieve a rapid current increase. This results in a slow dynamic current adjustment time. Using a dissipative electronic load, on the other hand, allows for faster dynamic current adjustment time, but struggles to meet energy-saving requirements. Summary of the Invention

[0062] The following is based on Figures 1 to 13 An output control method, device, system, electronic device, and storage medium provided in embodiments of the present application are described.

[0063] The present application provides an output control method, which is applied to an electronic load system, such as Figure 1 As shown, the electronic load system includes a controller ( Figure 1), a first consumable electronic load 100, a second consumable electronic load 110 and a regenerative electronic load 200, wherein the first consumable electronic load 100 and the regenerative electronic load 200 are arranged in series between the positive electrode of the power supply 300 under test and the negative electrode of the power supply 300 under test, and the second consumable electronic load 110 is arranged between the positive electrode of the power supply 300 under test and the negative electrode of the power supply 300 under test, as shown in FIG. Figure 2 As shown, the method includes a current control strategy, which includes:

[0064] Step S100: obtaining a target current value;

[0065] Step S200: Based on the target current value, controlling the first consumptive electronic load 100 to output a first output current;

[0066] Step S300: Based on the target current value and the first output current, controlling the second consumable electronic load 110 to output a second output current; wherein a rising rate of the second output current is greater than a rising rate of the first output current;

[0067] Step S400: When the output current of the electronic load system is at the target current value, control the second consumptive electronic load 110 to output at a third output current, so that the output current of the electronic load system remains at the target current value until the output current of the feedback electronic load 200 reaches the target current value, wherein the third output current maintains a downward trend.

[0068] In this embodiment, since the output current of the regenerative electronic load 200 is connected in series with the first consumable electronic load 100, the output current of the regenerative electronic load 200 is equal to the output current of the first consumable electronic load 100. Based on the target current value, the first consumable electronic load 100 is controlled to output at a first output current. Based on the target current value and the first output current, the second consumable electronic load 110 is controlled to output at a second output current, thereby rapidly increasing the output current of the electronic load system and meeting the current dynamic response speed requirement. When the output current of the electronic load system reaches the target current value, since the output current of the first consumable electronic load 100 continues to increase, the second consumable electronic load 110 is controlled to output at a third output current, i.e., the output current of the second consumable electronic load 110 decreases, thereby maintaining the output current of the electronic load system at the target current value until the output current of the regenerative electronic load 200 reaches the target current value. Energy is then fed back to the power grid through the regenerative electronic load 200, thereby meeting the energy conservation requirement.

[0069] In some embodiments of the present application, Figure 3As shown, the first consumptive electronic load 100 includes a first MOS transistor Q2, a source of the first MOS transistor Q2 connected to the negative electrode of the power supply 300 under test, a drain of the first MOS transistor Q2 connected to the positive electrode of the power supply 300 under test, and a gate of the first MOS transistor Q2 connected to the controller.

[0070] In some embodiments of the present application, Figure 3 As shown, the first consumptive electronic load 100 includes a first MOS transistor Q2 , a drain of the first MOS transistor Q2 is connected to the positive electrode of the power supply 300 under test, and a gate of the first MOS transistor Q2 is connected to the controller.

[0071] In some embodiments of the present application, Figure 3 As shown, the feedback electronic load 200 includes:

[0072] A first inductor L1, wherein a first end of the first inductor L1 is connected to a source of the first MOS transistor Q2;

[0073] a diode D1, where an anode of the diode D1 is connected to the second end of the first inductor L1;

[0074] A DC-AC converter T1 , wherein a first end of the DC-AC converter T1 is connected to the cathode of the diode D1 , and a second end of the DC-AC converter T1 is connected to the negative electrode of the power supply 300 under test;

[0076] a second capacitor C2, wherein a first end of the second capacitor C2 is connected to the cathode of the diode D1, and a second end of the second capacitor C2 is connected to the negative electrode of the power supply 300 under test;

[0077] The second MOS transistor Q3 has a source connected to the negative electrode of the measured power supply 300 , a drain connected to the second end of the first inductor L1 , and a gate connected to the controller.

[0078] In some embodiments of the present application, Figure 3 As shown, the second consumptive electronic load 110 includes a third MOS transistor Q1 , a drain of the third MOS transistor Q1 connected to the positive electrode of the power supply 300 under test, a gate of the third MOS transistor Q1 connected to the controller, and a source of the third MOS transistor Q1 connected to the negative electrode of the power supply 300 under test.

[0079] In some embodiments of the present application, the step S200 of “controlling the first consumable electronic load 100 to output at the first output current based on the target current value” is further described. The step S200 includes:

[0080] Step S210: determining a first rising curve based on the target current value;

[0081] Step S220: Based on the first rising curve, controlling the first consumptive electronic load 100 to output at a first output current;

[0082] Further describing the step S300 of “controlling the second consumable electronic load 110 to output at the second output current based on the target current value and the first output current”, step S300 includes:

[0083] Step S310: determining a second rising curve according to the target current value and the first rising curve;

[0084] Step S320 : Based on the second rising curve, control the second consumptive electronic load 110 to output at a second output current, wherein the slope of the second rising curve is greater than the slope of the first rising curve.

[0085] In this embodiment, the current preset output curve of the electronic load system is as follows: Figure 4 As shown. For the first consumer electronic load 100, as Figure 6 As shown, based on the target current value, a first rising curve is determined, and the controller controls the first consumable electronic load 100 to output a first output current according to the first rising curve, wherein the first rising curve includes multiple first time nodes and multiple first current values, and the multiple first current values ​​correspond one-to-one to the multiple first time nodes.

[0086] like Figure 5 As shown, for the second consumable electronic load 110, once the first rising curve is determined, the controller determines a second rising curve based on the target current value and the first rising curve. The controller controls the second consumable electronic load 110 to output a second output current based on the second rising curve, compensating for the difference between the first output current and the target current value using the second output current. The second rising curve includes multiple second time nodes and multiple second current values, each corresponding to the multiple second time nodes. The slope of the second rising curve is greater than that of the first rising curve, thereby improving the current dynamic response speed of the electronic load system.

[0087] In some embodiments of the present application, a difference circuit may be provided in the electronic load system, and the difference between the first output current and the target current value may be calculated using the difference circuit to determine the second output current.

[0088] In some embodiments of the present application, the step S400 of “controlling the second consumable electronic load 110 to output at a third output current so that the output current of the electronic load system is maintained at a target current value” is further described. The step S400 includes:

[0089] Step S410: determining a first descending curve according to the target current value and the first ascending curve;

[0090] Step S420 : Based on the first decreasing curve, control the second consumable electronic load 110 to output at a third output current, so that the output current of the electronic load system is maintained at the target current value.

[0091] In this embodiment, once the first rising curve is determined, a first falling curve is determined based on the target current value and the first rising curve. When the output current of the electronic load system reaches the target current value, that is, when the sum of the first output current and the second output current reaches the target current value, the controller controls the second consumptive electronic load 110 to output a third output current based on the first falling curve. The third output current compensates for the difference between the first output current and the target current value until the output current of the feedback electronic load 200 reaches the target current value. The first falling curve includes multiple third time nodes and multiple current values, and the multiple third current values ​​correspond one-to-one with the multiple third time nodes.

[0092] In some embodiments of the present application, the step S300 of “controlling the second consumable electronic load 110 to output at the second output current based on the target current value and the first output current” is further described. Step S300 includes:

[0093] Step S330: Determine a first intermediate output current using a first preset prediction model based on the target current value and the first output current; wherein the first preset prediction model is trained based on historical data of the electronic load system;

[0094] Step S340: determining a second output current according to the first intermediate output current and the target current value;

[0095] Step S350 : Control the second consumptive electronic load 110 to output at a second output current.

[0096] In this embodiment, a neural network model is trained using historical data from the electronic load system to obtain a first preset prediction model. The target current value and the real-time value of the first output current are input into the first preset prediction model. The first preset prediction model outputs a first intermediate output current, which is the current value of the first output current predicted by the first preset prediction model at the next time point. Based on the first intermediate output current and the target current value, the second output current is determined. The difference between the first intermediate output current and the target current value is the current value of the second output current at the next time point. The controller controls the second consumable electronic load 110 to output at the second output current.

[0097] In some embodiments of the present application, the type of neural network model to be trained is not limited. For example, a long short-term memory network, a sequential convolutional network, or a Transformer model can be trained to obtain a first preset prediction model.

[0098] In some embodiments of the present application, the step S400 of “controlling the second consumable electronic load 110 to output at a third output current so that the output current of the electronic load system is maintained at a target current value” is further described. The step S400 includes:

[0099] Step S430: Determine a first intermediate output current using a first preset prediction model based on the target current value and the first output current; wherein the first preset prediction model is trained based on historical data of the electronic load system;

[0100] Step S440: determining a third output current according to the first intermediate output current and the target current value;

[0101] Step S450 : controlling the second consumptive electronic load 110 to output at a third output current, so that the output current of the electronic load system is maintained at a target current value.

[0102] In this embodiment, the target current value and the real-time value of the first output current are input into a first preset prediction model. The first preset prediction model outputs a first intermediate output current, which is the current value of the first output current predicted by the first preset prediction model at the next time point. Based on the first intermediate output current and the target current value, the third output current is determined. The difference between the first intermediate output current and the target current value is the current value of the third output current at the next time point. The controller controls the second consumable electronic load 110 to output at the third output current, so that the output current of the electronic load system remains at the target current value.

[0103] In some embodiments of the present application, the current control strategy further includes:

[0104] In response to the current output end instruction, the first consumer electronic load 100 is controlled to output at a fourth output current based on the preset current output curve until the output current of the electronic load system returns to a steady-state operating current.

[0105] In this embodiment, in response to the current output end instruction, the first consumable electronic load 100 is controlled to output at the fourth output current based on the preset current output curve until the output current of the electronic load system returns to the steady-state operating current, and the dynamic response of the electronic load system is fast.

[0106] In some embodiments of the present application, the method further includes a constant voltage output control strategy:

[0107] Step S1000: obtaining a target voltage value;

[0108] Step S2000: Based on the target voltage value, controlling the feedback electronic load 200 to output a first output voltage;

[0109] Step S3000: Based on the target voltage value and the first output voltage, controlling the first consumable electronic load 100 to output at a second output voltage; wherein a rising speed of the second output voltage is greater than a rising speed of the first output voltage;

[0110] Step S4000: When the output voltage of the electronic load system is at the target voltage value, control the first consumer electronic load 100 to output at a third output voltage, so that the output voltage of the electronic load system remains at the target voltage value until the output voltage of the feedback electronic load 200 reaches the target voltage value, wherein the third output voltage maintains a downward trend.

[0111] In an embodiment of the present application, based on a target voltage value, the controller controls the feedback electronic load 200 to output at a first output voltage. Based on the target voltage value and the first output voltage, the controller controls the first consumable electronic load 100 to output at a second output voltage, so that the output voltage of the electronic load system rises rapidly, meeting the voltage dynamic response speed requirement. When the output voltage of the electronic load system reaches the target voltage value, since the output voltage of the feedback electronic load 200 continues to rise, the controller controls the first consumable electronic load 100 to output at a third output voltage, that is, the output voltage of the first consumable electronic load 100 decreases, so that the output voltage of the electronic load system remains at the target voltage value until the output voltage of the feedback electronic load 200 reaches the target voltage value, at which point the feedback electronic load 200 alone performs voltage output, meeting the energy-saving requirement.

[0112] In step S1000 , the target voltage value is the output voltage value of the electronic load system required for testing the power supply 300 under test.

[0113] In step S2000, based on the target voltage value, the regenerative electronic load 200 can control the first output voltage to increase from the steady-state operating voltage at a controllable fixed slope. The regenerative electronic load 200 can also control the first output voltage to increase nonlinearly from the steady-state operating voltage at a maximum voltage build-up rate.

[0114] In step S3000, because the voltage dynamic response speed of the regenerative electronic load 200 is relatively slow, the controller controls the first consumable electronic load 100 to output at a second output voltage based on the target voltage value and the first output voltage. By superimposing the output voltages of the regenerative electronic load 200 and the first consumable electronic load 100, and by increasing the second output voltage at a faster rate, the output voltage of the electronic load system increases rapidly, thereby improving the voltage dynamic response speed.

[0115] In step S4000, when the output voltage of the electronic load system is at the target voltage value, that is, when the sum of the first output voltage and the second output voltage reaches the target voltage value, the first output voltage continues to rise, and the controller controls the first consumable electronic load 100 to output at the third output voltage. The third output voltage maintains a downward trend, so that the output voltage of the electronic load system remains at the target voltage value until the output voltage of the feedback electronic load 200 reaches the target voltage value.

[0116] In some embodiments of the present application, the step S2000 of “controlling the feedback electronic load 200 to output the first output voltage based on the target voltage value” is further described. The step S2000 includes:

[0117] Step S2100: determining a first rising curve based on the target voltage value;

[0118] Step S2200: Based on the first rising curve, control the feedback electronic load 200 to output a first output voltage;

[0119] Further describing the step S3000 of “controlling the first consumable electronic load 100 to output at the second output voltage based on the target voltage value and the first output voltage”, step S3000 includes:

[0120] Step S3100: determining a second rising curve according to the target voltage value and the first rising curve;

[0121] Step S3200 : Based on the second rising curve, control the first consumer electronic load 100 to output at a second output voltage, wherein the slope of the second rising curve is greater than the slope of the first rising curve.

[0122] In this embodiment, for the feedback electronic load 200, a first rising curve (eg, Figure 8 As shown in the section t1 to t3 in FIG, the controller controls the feedback electronic load 200 to output the first output voltage according to the first rising curve, wherein the first rising curve includes a plurality of first time nodes and a plurality of first voltage values, and the plurality of first voltage values ​​correspond one-to-one to the plurality of first time nodes.

[0123] For the first consumable electronic load 100, when the first rising curve is determined, the controller determines the second rising curve (eg, Figure 9 (as shown in the section t1 to t2 in the figure), the first consumable electronic load 100 is controlled to output a second output voltage according to the second rising curve, and the difference between the first output voltage and the target voltage value is compensated by the second output voltage. The second rising curve includes multiple second time nodes and multiple second voltage values, and the multiple second voltage values ​​correspond to the multiple second time nodes in a one-to-one manner. The slope of the second rising curve is greater than the slope of the first rising curve, thereby improving the voltage dynamic response speed of the electronic load system. The output voltage of the electronic load system is as shown in FIG. Figure 7 shown.

[0133] In this embodiment, a neural network model is trained using historical data from the electronic load system to obtain a first preset prediction model. The target voltage value and the real-time value of the first output voltage are input into the first preset prediction model. The first preset prediction model outputs a first intermediate output voltage, which is the voltage value of the first output voltage predicted by the first preset prediction model at the next time point. Based on the first intermediate output voltage and the target voltage value, the second output voltage is determined. The difference between the first intermediate output voltage and the target voltage value is the voltage value of the second output voltage at the next time point. The controller controls the first consumable electronic load 100 to output at the second output voltage.

[0134] In some embodiments of the present application, the type of neural network model to be trained is not limited. For example, a long short-term memory network, a sequential convolutional network, or a Transformer model can be trained to obtain a first preset prediction model.

[0135] In some embodiments of the present application, the step S4000 of “controlling the first consumable electronic load 100 to output at a third output voltage so that the output voltage of the electronic load system is maintained at a target voltage value” is further described. The step S4000 includes:

[0136] Step S4300: Determine a first intermediate output voltage based on the target voltage value and the first output voltage using a first preset prediction model, wherein the first preset prediction model is trained based on historical data of the electronic load system;

[0137] Step S4400: determining a third output voltage according to the first intermediate output voltage and the target voltage value;

[0138] Step S4500 : controlling the first consumer electronic load 100 to output at a third output voltage, so that the output voltage of the electronic load system is maintained at a target voltage value.

[0139] In this embodiment, the target voltage value and the real-time value of the first output voltage are input into a first preset prediction model. The first preset prediction model outputs a first intermediate output voltage, which is the voltage value of the first output voltage predicted by the first preset prediction model at the next time point. Based on the first intermediate output voltage and the target voltage value, the third output voltage is determined. The difference between the first intermediate output voltage and the target voltage value is the voltage value of the third output voltage at the next time point. The controller controls the first consumable electronic load 100 to output at the third output voltage, so that the output voltage of the electronic load system remains at the target voltage value.

[0140] In some embodiments of the present application, the method further comprises:

[0141] Step S5000 : In response to the prediction end instruction, controlling the feedback electronic load 200 to output at a fourth output voltage until the output voltage of the feedback electronic load 200 returns to a steady-state operating voltage;

[0142] Step S6000 : adjusting the output voltage of the first consumer electronic load 100 according to the preset voltage output curve and the decreasing speed of the output voltage of the feedback electronic load 200 , so that the output voltage of the electronic load system is consistent with the preset voltage output curve.

[0143] In this embodiment, the prediction end instruction is used to instruct the electronic load system to prepare to restore the output voltage to the steady-state operating voltage. In response to the prediction end instruction, the controller controls the feedback electronic load 200 to output the fourth output voltage (e.g., Figure 8 As shown in the section t4 to t6, Figure 10 As shown in the section t4 to t5 in FIG, the fourth output voltage maintains a downward trend until the output voltage of the feedback electronic load 200 returns to the steady-state operating voltage. The controller can determine the magnitude of the fourth output voltage based on the decreasing speed of the output voltage of the feedback electronic load 200, and further determine the difference between the fourth output voltage and the preset voltage output curve of the electronic load system, and adjust the output voltage of the first consumer electronic load 100 to the difference (as shown in FIG. Figure 9 As shown in the section t4 to t6, Figure 11 t4 to t6 in FIG), so that the output voltage of the electronic load system is consistent with the preset voltage output curve.

[0144] In step S5000, the prediction end instruction can be generated based on the preset voltage output curve of the electronic load system, for example, generated a certain time before the starting point of the decline of the preset voltage output curve, to indicate that the electronic load system is ready to restore the output voltage to the steady-state operating voltage.

[0145] In step S6000, if Figure 7As shown, the voltage preset output curve includes multiple fourth time nodes and multiple fourth voltage values, and the multiple fourth time nodes correspond to the multiple fourth voltage values ​​in a one-to-one manner.

[0146] In some embodiments of the present application, the step S6000 of “adjusting the output voltage of the first consumer electronic load 100 according to the preset voltage output curve and the decreasing rate of the output voltage of the feedback electronic load 200” is further described. Step S6000 includes:

[0147] Step S6100: In response to the prediction end instruction, controlling the first consumer electronic load 100 to output at a fifth output voltage, so that the output voltage of the electronic load system is maintained at the target voltage value;

[0148] Step S6200: In response to the voltage output end instruction, controlling the first consumer electronic load 100 to output at a sixth output voltage until the output voltage of the electronic load system returns to a steady-state output voltage; the sixth output voltage decreases faster than the fourth output voltage.

[0149] Among them, the output end instruction and the predicted end instruction are determined according to the voltage preset output curve, wherein the output end instruction is generated at the starting moment of the period when the electronic load system drops from the target voltage to the steady-state operating voltage, and the generation moment of the predicted end instruction is before the generation of the output end instruction.

[0150] In this embodiment, in response to the prediction end instruction, the feedback electronic load 200 outputs a fourth output voltage, which decreases at a fixed slope and returns to a steady-state operating voltage at a predetermined endpoint time. In response to the prediction end instruction, the controller controls the first consumer electronic load 100 to output a fifth output voltage, compensating for the difference between the fourth output voltage and the target voltage, thereby maintaining the output voltage of the electronic load system at the target voltage. In response to the voltage output end instruction, the controller controls the first consumer electronic load 100 to output a sixth output voltage, which decreases at a faster rate than the fourth output voltage, causing the output voltage of the electronic load system to decrease rapidly until the output voltage of the electronic load system returns to the steady-state output voltage at the endpoint time. The endpoint time is the fourth time point corresponding to when the fourth voltage value of the preset voltage output curve returns to the steady-state output voltage.

[0151] The prediction end instruction and the output end instruction are generated based on the voltage preset output curve of the electronic load system. For example, the output end instruction is generated at the fourth time node corresponding to the starting point of the period when the voltage preset output curve drops from the target voltage to the steady-state operating voltage, and the prediction end instruction is generated a certain time before the starting point of the period when the voltage preset output curve drops from the target voltage to the steady-state operating voltage, so that the generation time of the prediction end instruction is before the generation time of the output end instruction.

[0152] In some embodiments of the present application, the step S6000 of “adjusting the output voltage of the first consumer electronic load 100 according to the preset voltage output curve and the decreasing rate of the output voltage of the feedback electronic load 200” is further described. Step S6000 includes:

[0153] Step S6300: In response to the prediction end instruction, controlling the first consumer electronic load 100 to output at a fifth output voltage, so that the output voltage of the electronic load system is maintained at the target voltage value;

[0154] Step S6400: When the output voltage of the feedback electronic load 200 recovers from the target voltage to the steady-state operating voltage and the preset voltage output curve indicates that the electronic load system needs to maintain output, control the first consumer electronic load 100 to output at a sixth output voltage until the output voltage of the electronic load system recovers to the steady-state output voltage.

[0155] In this embodiment, in response to a prediction end instruction, the controller controls the first consumable electronic load 100 to output at a fifth output voltage, compensating for the difference between the fourth output voltage and the target voltage, thereby maintaining the output voltage of the electronic load system at the target voltage. When the output voltage of the feedback electronic load 200 recovers from the target voltage to the steady-state operating voltage, and the preset voltage output curve indicates that the electronic load system needs to maintain the target voltage output, the controller controls the first consumable electronic load 100 to output at a sixth output voltage, i.e., outputting at the difference between the target voltage and the steady-state operating voltage, thereby maintaining the output voltage of the electronic load system at the target voltage. In response to a voltage output end instruction, the controller controls the sixth output voltage of the first consumable electronic load 100 to rapidly decrease, thereby rapidly decreasing the output voltage of the electronic load system until the output voltage of the electronic load system returns to the steady-state output voltage at the end time node.

[0156] In some embodiments of the present application, the step S6000 of “adjusting the output voltage of the first consumer electronic load 100 according to the preset voltage output curve and the decreasing rate of the output voltage of the feedback electronic load 200” is further described. Step S6000 includes:

[0157] Step S6500: If the output voltage of the regenerative electronic load 200 has not recovered to the steady-state output voltage and the preset voltage output curve indicates that the electronic load system needs to maintain output, a second intermediate output voltage is determined based on the steady-state output voltage and the fourth output voltage using a second preset prediction model. A seventh output voltage is also determined based on the second intermediate output voltage and the steady-state output voltage, and the first consumer electronic load 100 is controlled to output the seventh output voltage.

[0158] Step S6500: When the output voltage of the feedback electronic load 200 recovers to the steady-state output voltage and the preset voltage output curve indicates that the electronic load system needs to maintain output, control the first consumer electronic load 100 to output at the eighth output voltage until the output voltage of the electronic load system recovers to the steady-state output voltage.

[0159] In this embodiment, in the regenerative electronic load 200, a neural network model is trained using historical data of the electronic load system to obtain a second preset prediction model. If the output voltage of the regenerative electronic load 200 has not recovered to the steady-state output voltage and the preset voltage output curve indicates that the electronic load system needs to maintain the output target voltage value, the second preset prediction model is used to determine the voltage value of the fourth output voltage at the next time node based on the steady-state output voltage and the fourth output voltage. Based on the second intermediate output voltage and the steady-state output voltage, the voltage value of the first consumable electronic load 100 at the next time node is determined to compensate for the difference between the fourth output voltage and the target voltage value, i.e., to determine the seventh output voltage, and the seventh output voltage of the first consumable electronic load 100 is then controlled.

[0160] When the output voltage of the feedback electronic load 200 recovers to the steady-state output voltage and the preset voltage output curve indicates that the electronic load system needs to maintain the output target voltage value, the first consumer electronic load 100 is controlled to output at the eighth output voltage until the output voltage of the electronic load system recovers to the steady-state output voltage.

[0161] In some embodiments of the present application, the type of neural network model to be trained is not limited. For example, a long short-term memory network, a sequential convolutional network, or a Transformer model can be trained to obtain a second preset prediction model.
