Description

Technical Field

[0001] The present invention relates to the technical field of performance testing, and particularly to a dynamic performance testing system for a shock converter. Background Art

[0002] A shock converter is a device used in power electronic systems, mainly for handling transient voltage or current shocks. Its core function is to convert the input voltage or current waveform through specific circuit designs to protect subsequent circuits or devices from the impacts of transient overvoltage, overcurrent, etc. Shock converters are widely used in power systems, communication devices, industrial automation, etc., and are important components to ensure the stable operation of the system. During the use of shock converters, it is necessary to test the performance of shock converters, mainly to ensure the reliability of the equipment and ensure that it can operate stably under various extreme conditions, and to prevent the equipment from failing due to insufficient performance in critical applications, resulting in system paralysis or safety accidents.

[0003] A test device for a DC / DC converter and a power supply test system with the patent publication number CN110673055A only need to connect to the power grid at one point of the compensation power supply, rather than reconnecting the electronic load to the power grid at the back end for feedback. Therefore, fewer devices are required, saving space. At the same time, it will not cause disturbances to the power grid. The electric energy circulates self - contained within the test device. After each test cycle, the compensation power supply compensates for the lost energy, which not only saves electric energy but also does not interfere with the power grid. There is no need to add power grid isolation equipment, saving space and having higher efficiency. It can also cooperate with inductors and constant - voltage electronic loads to filter out low - frequency and high - frequency ripples and improve the accuracy of detection.

[0004] In the process of detecting a shock converter with the above - mentioned and similar technical solutions, since the shock converter converts the input voltage or current waveform into appropriate output data, and during the use of the shock converter, the input voltage or current is not fixed. Therefore, conventional constant detection methods cannot detect the impact of fluctuating voltage or current on the shock converter. When the input voltage or current changes, there may be a problem that the target shock converter has a slow response speed at a certain fixed voltage or current, resulting in the inability to quickly detect the fault points of the shock converter.

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0039] Conventional shock converter detection methods usually use static constant voltage or constant current sources for testing. Although this method is simple and easy to implement and can evaluate the static characteristics of shock converters at specific operating points, such as conversion efficiency, output ripple, etc., however, the input voltage or current in actual applications often changes dynamically, such as transient changes in the power supply load, output fluctuations of solar panels, fluctuations in the grid voltage, etc. These fluctuations will directly affect the operating state of the shock converter and may trigger potential failures. For example, when the input voltage suddenly drops, the control circuit of the shock converter needs to adjust the duty cycle in a timely manner to maintain the stability of the output voltage. If the response speed of the control circuit is not fast enough, or the compensation parameters are set unreasonably, it will cause a large drop in the output voltage and even trigger overcurrent protection, resulting in system shutdown. Therefore, relying solely on static detection cannot comprehensively evaluate the performance of shock converters in actual working environments. It cannot reveal the transient response characteristics of shock converters when facing dynamic inputs, such as response time, overshoot, undershoot, etc. These problems are difficult to detect under constant input conditions but will significantly affect the performance of shock converters and even induce failures under dynamic input conditions. The technical solution provided in this application obtains the model identification data of the target shock converter, and based on the model identification data, obtains the basic information of the target shock converter. Through data query, the identification information and attribute information of the target shock converter are obtained to obtain the required information, and the required information includes the input limit value and output limit value of the target shock converter. Therefore, the detection span value can be set according to the required information. According to the set detection span value, after obtaining the actual input information and output information of the target shock converter, according to the combined results of each with the detection span value, multiple combined results of input data and output data are obtained, thereby realizing the detection of the performance of the shock converter in the current working state, and achieving the effect of drawing inferences from one instance. At the same time, the performance in multiple other states is detected, providing a stronger detection effect for the shock converter. At the same time, by continuously detecting the working state of the shock converter, when the working input data or output data of the shock converter changes, the changed targets are respectively set as the updated input item or the updated output item, and the updated input item or the updated output item is recombined with the set detection span value to obtain multiple groups of combinations that can be used for performance testing again, thereby realizing the dynamic performance detection effect of the cluster converter. Specifically in this application, as Figure 1 shown, it includes steps S100 - S800.

[0040] An impact converter dynamic performance test system, comprising: an acquisition module: acquiring the attribute information of a target impact converter to obtain target attribute items, obtaining requirement information based on the target attribute items to obtain requirement information items, setting a detection span value, and obtaining a detection span item based on the combined result of the requirement information items and the detection span value; a detection module: acquiring the real-time conversion data of the target impact converter during operation, the real-time conversion data including a target input item and a target output item, setting detection input data and detection output data through a first combination method to obtain a detection input set and a detection output set; an analysis module: acquiring the response time and the change time when the detection input set changes to the detection output set to obtain an output response set and an output change set, setting a detection method to obtain the average values of the output response set and the output change set to obtain a response average item and a change average item, and acquiring the test feedback information of the target impact converter based on the response average item and the change average item to perform a matching detection on the working state of the target impact converter; a dynamic module: determining whether the target input item and the target output item fluctuate, and obtaining updated input items and updated output items when the target input item and the target output item fluctuate; a change module: setting detection input data and output data through a second combination method based on the updated input items and the updated output items to obtain an updated input set and an updated output set, and further obtaining an updated response set and an updated change set, determining whether the response average item and the change average item are successfully acquired, and adjusting the updated input set and the detection input set through an adjustment method to perform dynamic detection on the impact converter.

[0041] Step S100: Acquire the attribute information of the target impact converter to obtain target attribute items.

[0042] It should be noted that, as Figure 2 shown, model identification data is stored on the target impact converter, and the method for obtaining the target attribute items includes: based on the model identification data, obtaining the basic information of the target impact converter, and based on the basic information, obtaining the identification information and attribute information of the target impact converter through data query to obtain the target attribute items.

[0043] Specifically, after the impact converter is normally put into use, its device itself will come with model identification data, and the basic information of the impact converter can be obtained according to the model identification data, so that the attribute information of the target impact converter can be obtained through big data query.

[0044] Embodiment 1

[0045] In a specific implementation process, it is now necessary to perform a performance test on a shock converter A that is in a working state. The model identification data attached to the shock converter A is ABB OVR Series. Based on this model identification data, the attribute information of the shock converter A is obtained through big data query. The attribute information is: input voltage 100V - 1000V, output voltage 50V - 500V.

[0046] Step S200: Obtain requirement information based on the target attribute item to get requirement information items, set a detection span value, and based on the combination result of the requirement information items and the detection span value, obtain a detection span item.

[0047] It should be noted that, as Figure 3 shown, the requirement information includes the input limit value and the output limit value of the target shock converter. The method for obtaining the detection span item includes: based on the requirement information items, obtain the input limit value range and the output limit value range to get an input range item and an output range item; set a detection span value, and the detection span value is a fixed ratio value, the detection span value is ±1%, obtain the limit value difference information of the input range item and the output range item to get an input difference item and an output difference item; based on the combination result of the input difference item and the output difference item and the detection span value, obtain an input span item and an output span item, and the input span item and the output span item are combined to obtain the detection span item.

[0048] Embodiment 2

[0049] In a specific implementation process, the attribute information of a shock converter A is: input voltage 100V - 1000V, output voltage 50V - 500V, that is, the input limit value range is 100V - 1000V, and the output limit value range is 50V - 500V. At this time, the limit value difference information of the input range item and the output range item is 900V and 450V respectively. At this time, according to the set detection span value of ±1%, it is combined with the input difference item and the output difference item respectively to obtain that the input span item and the output span item are ±9V and ±4.5V respectively.

[0050] Step S300: Obtain the real-time conversion data of the target shock converter during operation. The real-time conversion data includes a target input item and a target output item. Set the detection input data and the detection output data through the first combination method to obtain a detection input set and a detection output set.

[0051] It should be noted that the first combination method includes: input combination: based on the combination result of the input span item and the target input item, obtain the detection input set; output combination: based on the combination result of the output span item and the target output item, obtain the detection output set.

[0052] Embodiment 3

[0053] In a specific implementation process, during the use of a certain impact converter A, the input limit value range is 100V - 1000V, the output limit value range is 50V - 500V, the input span term and the output span term are ±9V and ±4.5V respectively. It is obtained that during a certain power conversion process, a voltage of 500V is converted into 100V. At this time, the target input term is 500V and the target output term is 100V. At this time, according to the combined result of the input span term and the target input term, the detected input set is obtained as 491V, 500V, and 509V. According to the combined result of the output span term and the target output term, the detected output set is obtained as 95.5V, 100V, and 104.5V.

[0054] Step S400: Obtain the response time and change time for the detected input set to change to the detected output set, and obtain the output response set and the output change set.

[0055] It should be noted that the methods for obtaining the output response set and the output change set include: separately splitting the detected input set and the detected output set to obtain at least one detected input term and at least one detected output term; based on the corresponding relationship between the detected input term and the detected output term, obtaining the combined result of the detected input term and the detected output term, and respectively obtaining the response time and the change time based on the combined result to obtain the output response set and the output change set.

[0056] Embodiment 4

[0057] In a specific implementation process, as Figure 4 shown, the detected input set of the impact converter A is obtained as 491V, 500V, and 509V, and the detected output set is 95.5V, 100V, and 104.5V. At this time, the detected input set and the detected output set are separately split, and based on the corresponding relationship between the detected input term and the detected output term, the combined result of the detected input term and the detected output term is obtained. The combined results are 491V - 95.5V, 491V - 100V, 491V - 104.5V, 500V - 95.5V, 500V - 100V, 500V - 104.5V, 509V - 95.5V, 509V - 100V, 509V - 104.5V, a total of nine kinds. The response time and the change time are respectively obtained. The response times are 25ns, 23ns, 21ns, 27ns, 26ns, 25ns, 23ns, 22ns, 22ns, and the change times are 1µs, 0.9µs, 0.8µs, 0.9µs, 1µs, 0.8µs, 1µs, 0.9µs, 1µs. Then the output response set and the output change set are obtained.

[0058] Step S500: Set a detection method to obtain the average values of the output reaction set and the output change set, and obtain the reaction average term and the change average term.

[0059] It should be noted that the detection method includes: setting the detection average value, with the detection average value being 10 times. Continuously detect the target impact converter based on the detection average value with the detection input set, obtain the average values of the reaction time and the change time when the detection input set changes to the detection output set, and then obtain the reaction average term and the change average term. Obtain the test feedback information of the target impact converter based on the reaction average term and the change average term.

[0060] Specifically, according to the set detection average value, detect the average values of the reaction time and the change time when different detection input sets change to the detection output set, so as to obtain the average reaction time and the change time, which are used to represent the reaction time and the change time of the combination results of the detection input item and the detection output item under different combinations.

[0061] In the specific implementation process, the combination results of the detection input item and the detection output item are 491V - 95.5V, 491V - 100V, 491V - 104.5V, 500V - 95.5V, 500V - 100V, 500V - 104.5V, 509V - 95.5V, 509V - 100V, 509V - 104.5V, a total of nine kinds. When the detection average value is 10 times, obtain the reaction time and the change time respectively. The average reaction times are 24ns, 24ns, 21ns, 27ns, 25ns, 22ns, 23ns, 25ns, 21ns respectively, and the average change times are 1µs, 0.99µs, 0.82µs, 0.95µs, 1.05µs, 0.85µs, 0.89µs, 0.89µs, 0.5µs respectively, and then obtain the reaction average term and the change average term.

[0062] Step S600: Determine whether the target input item and the target output item fluctuate. When the target input item and the target output item fluctuate, obtain the updated input item and the updated output item.

[0063] It should be noted that the method for obtaining the updated input item and the updated output item includes: continuously obtaining the real-time conversion data of the target impact converter during operation, and obtaining the data trend information of the target input item and the target output item; judging whether the trend fluctuates based on the data trend information. When the trend fluctuates, obtain the fluctuation point data information, which is set as the fluctuation feedback item. Based on the source of the fluctuation feedback item, when the source is an input fluctuation, obtain the updated input item, and when the source is an output fluctuation, obtain the updated output item.

[0064] Specifically, such as Figure 5As shown, the impact converter A converts a voltage of 500V into 100V. At this time, the target input item is 500V, and the target output item is 100V. Continuously obtaining the target input item and the target output item, the trend information of the target input item is 500V, 500V, 500V, 500V, 600V, and the trend information of the target output item is 100V, 100V, 100V, 100V, 130V. At this time, it is obtained that the trend information of both the target input item and the target output item has changed. The change points are set as the fluctuation feedback items, and then the updated input item and the updated output item are obtained, which are 600V and 130V respectively.

[0065] Step S700: Based on the updated input item and the updated output item, set the detection input data and output data through the second combination method to obtain the updated input set and the updated output set, and then obtain the updated reaction set and the updated change set.

[0066] It should be noted that the second combination method includes: obtaining the updated input set based on the combination result of the input span item and the updated input item, and obtaining the updated output set based on the combination result of the output span item and the updated output item.

[0067] Specifically, during the continuous detection of the target input item and the target output item, when the target input item or the target output item changes, the changed target is set as the updated input item or the updated output item. The input span item and the output span item are ±9V and ±4.5V respectively. At this time, according to the combination result of the input span item and the updated input item, the updated input set is obtained, and the combination result of the output span item and the updated output item can obtain the updated output set.

[0068] In the specific implementation process, it is obtained that during a certain power conversion process, the impact converter A converts a voltage of 500V into 100V. At this time, the target input item is 500V, and the target output item is 100V. The input span item and the output span item are ±9V and ±4.5V respectively. After this change is completed, the 500V voltage is repeatedly converted into 100V until three times later, when the 500V voltage needs to be converted into 120V, and at this time the target output item changes. That is, 120V is set as the updated output item. According to the set input span item and output span item, the updated input set is the detection input set at this time, which is 491V, 500V, and 509V, and the updated output set is 115.5V, 120, and 124.5V.

[0069] Step S800: Determine whether the reaction average item and the change average item are successfully obtained, and adjust the updated input set and the detection input set through the adjustment method.

[0070] It should be noted that the adjustment method includes: when the reaction average term and the change average term are not fully obtained, taking the average values of the updated reaction time and the updated change time as a replacement, setting the unfinished part as the first preparatory item, and re-obtaining the first preparatory item after completing the updated reaction set and the updated change set, and dynamically detecting the impact converter.

[0071] Specifically, since the set detection average value is 10 times, it is necessary to detect the target impact converter with the detection input set at a frequency of 10 times, and obtain the average values of the reaction time and the change time when the detection input set changes to the detection output set. However, when the 10 - time detection is not completed, the target input item or the target output item changes. At this time, taking the average values of the updated reaction time and the updated change time as a replacement, that is, detecting the target impact converter with the updated input set at a frequency of 10 times, and obtaining the average values of the reaction time and the change time when the updated input set changes to the updated output set, and determining the average values of the reaction time and the change time when the remaining unfinished detection input set changes to the detection output set as the first preparatory item, and re - obtaining the remaining unfinished part after completing the updated reaction set and the updated change set.

[0072] In a specific implementation process, during the acquisition module stage, the attribute information of the target impact converter is acquired. Impact converter A, which is in a working state, is obtained. The model identification data attached to impact converter A is ABB OVRSeries. Based on this model identification data, the attribute information of impact converter A is obtained through big data query. The attribute information is: input voltage 100V - 1000V, output voltage 50V - 500V. That is, the target attribute items of impact converter A are obtained as: input voltage 100V - 1000V, output voltage 50V - 500V. Subsequently, it is necessary to obtain the demand information based on the target attribute items to obtain the demand information items. The demand information includes the input limit value and the output limit value of the target impact converter, and then the input range item and the output range item are obtained. Since the target attribute items are: input voltage 100V - 1000V, output voltage 50V - 500V, at this time, the input limit value range is 100V - 1000V, and the output limit value range is 50V - 500V. The detection span value is set. Based on the combination result of the demand information items and the detection span value, the detection span item is obtained. The detection span value is a fixed ratio value, and the detection span value is ±1%. According to the input limit value range and the output limit value range, the limit value difference information of the input range item and the output range item is obtained to obtain the input difference item and the output difference item. At this time, the input difference item and the output difference item are respectively: 1000V - 100V = 900V, 500V - 50V = 450V. According to the combination result of the set detection span item of ±1% and the input difference item and the output difference item, the input span item and the output span item are respectively 900V * ±1% = ±9V, 450V * 1% = ±4.5V;

[0073] In the detection module stage, it is necessary to obtain the real-time conversion data of the target impact converter during operation. The real-time conversion data includes the target input item and the target output item. The detection input data and the detection output data are set by the first combination method, and the first combination method includes: input combination: based on the combination result of the input span item and the target input item, obtain the detection input set; output combination: based on the combination result of the output span item and the target output item, obtain the detection output set. Suppose an impact converter A is in use, the input limit value range is 100V - 1000V, and the output limit value range is 50V - 500V. At this time, according to the calculation: 900V * ±1% = ±9V, 450V * 1% = ±4.5V, it is obtained that the input span item and the output span item are ±9V and ±4.5V respectively. It is obtained that during a certain power conversion process, a voltage of 500V is converted into 100V. At this time, the target input item is 500V, and the target output item is 100V. At this time, according to the combination result of the input span item and the target input item: 500V and 500V ± 9V, the detection input set is obtained as 491V, 500V, and 509V. According to the combination result of the output span item and the target output item: 100V and 100V ± 4.5V, the detection output set is obtained as 95.5V, 100V, and 104.5V;

[0074] In the analysis module stage, it is necessary to obtain the reaction time and change time when the detection input set changes to the detection output set. The methods for obtaining the output reaction set and output change set include: separately splitting the detection input set and the detection output set to obtain at least one detection input item and at least one detection output item. The detection input set of the impact converter A is 491V, 500V, and 509V, and the detection output set is 95.5V, 100V, and 104.5V. At this time, the detection input set and the detection output set are separately split. Based on the corresponding relationship between the detection input item and the detection output item, the combined results of the detection input item and the detection output item are 491V - 95.5V, 491V - 100V, 491V - 104.5V, 500V - 95.5V, 500V - 100V, 500V - 104.5V, 509V - 95.5V, 509V - 100V, 509V - 104.5V, a total of nine kinds. The reaction time and change time of the actual detection input and output are detected by an oscilloscope: the reaction times are 25ns, 23ns, 21ns, 27ns, 26ns, 25ns, 23ns, 22ns, 22ns respectively, and the change times are 1µs, 0.9µs, 0.8µs, 0.9µs, 1µs, 0.8µs, 1µs, 0.9µs, 1µs respectively. Then the output reaction set and output change set are obtained. Set the average values of the output reaction set and output change set obtained by the detection method. The detection method includes: setting the detection average value, and the detection average value is 10 times. Based on the detection average value, continuously detect the target impact converter with the detection input set to obtain the average values of the reaction time and change time when the detection input set changes to the detection output set, and then obtain the reaction average item and change average item. Since the combined results of the detection input item and the detection output item are 491V - 95.5V, 491V - 100V, 491V - 104.5V, 500V - 95.5V, 500V - 100V, 500V - 104.5V, 509V - 95.5V, 509V - 100V, 509V - 104.5V, a total of nine kinds. When the detection average value is 10 times, the reaction time and change time are respectively obtained. In the 10 detections of 491V - 95.5V detected by the oscilloscope, the reaction times are 23.5, 24.2, 23.8, 24.5, 23.7, 24.1, 23.9, 24.3, 23.6, 24.4 respectively. At this time, the average reaction time is:

[0075] ;

[0076] Obtain and calculate the remaining detections in the same way. The average reaction times obtained are 24ns, 21ns, 27ns, 25ns, 22ns, 23ns, 25ns, 21ns respectively, and the average change times are 1µs, 0.99µs, 0.82µs, 0.95µs, 1.05µs, 0.85µs, 0.89µs, 0.89µs, 0.5µs respectively. Then obtain the average reaction term and the average change term, and based on the average reaction term and the average change term, obtain the test feedback information of the target impact converter, and perform a matching detection on the working state of the target impact converter;

[0077] In the dynamic module stage, by judging whether the target input item and the target output item fluctuate, continuously obtain the real-time conversion data of the target impact converter during operation, and obtain the data trend information of the target input item and the target output item; based on the data trend information, judge whether the trend fluctuates. When the trend fluctuates, obtain the fluctuation point data information and set it as the fluctuation feedback item. Based on the mapping source of the fluctuation feedback item, when the source is input fluctuation, obtain the updated input item, and when the source is output fluctuation, obtain the updated output item. Impact converter A converts a voltage of 500V into 100V. At this time, the target input item is 500V and the target output item is 100V. Continuously obtain the target input item and the target output item. The trend information of the target input item is 500V - 500V - 500V - 500V - 600V, and the trend information of the target output item is 100V - 100V - 100V - 100V - 130V. At this time, it is obtained that the trend information of the target input item and the target output item has both changed, and both are in the fifth target input item and target output item. Set the change point as the fluctuation feedback item, and then obtain the updated input item and the updated output item, which are 600V and 130V respectively;

[0078] In the change module stage, based on the updated input items and updated output items, the input data and output data for detection are set through a second combination method. The second combination method includes: obtaining an updated input set based on the combination result of the input span item and the updated input item, obtaining an updated output set based on the combination result of the output span item and the updated output item. It is obtained that during a certain power conversion process, the impact converter A converts a voltage of 500V into 100V. At this time, the target input item is 500V, the target output item is 100V, the input span item and the output span item are ±9V and ±4.5V respectively. After this change is completed, the conversion of 500V voltage to 100V is repeated until three times later, when the voltage of 500V needs to be converted to 120V. At this time, the target output item changes, and 120V is set as the updated output item. According to the set input span item and output span item, the updated input set, which is the detection input set, is 491V, 500V, and 509V, while the updated output set is 115.5V, 120, and 124.5V. Determine whether the reaction average item and the change average item are successfully obtained. When the reaction average item and the change average item are not fully obtained, use the average values of the updated reaction time and the updated change time as a replacement, and set the unfinished part as the first preparatory item. After completing the updated reaction set and the updated change set, re-obtain the first preparatory item and perform dynamic detection on the impact converter, perform dynamic detection on the impact converter.

The scope of the present invention is defined by the appended embodiments and their equivalents.
