[0063] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0064] As mentioned in the background technology, power factor correction (PFC) is an important control part of air conditioners. The stability of PFC requires the accuracy of the hardware circuit included in PFC. In the related technology, the hardware circuit of PFC needs to be equipped with a corresponding test circuit to test the accuracy of the hardware circuit of PFC. The accuracy test process requires a lot of manpower and has low test efficiency.

[0065] In view of this, the present disclosure provides a method, device and medium for testing a PFC hardware circuit, which are used to solve the technical problem of low efficiency in accuracy testing of a PFC hardware circuit in the related art.

[0066] Figure 1 is a flow chart of a method for testing a PFC hardware circuit according to an exemplary embodiment. The method can be applied to air conditioning equipment, such as Figure 1 As shown, the method includes the following steps.

[0067] Step 110, in response to the received test instruction, determining a test process, the test process being used at least to verify an output voltage of a current sampling circuit included in the PFC hardware circuit and / or a demagnetization protection value of a demagnetization protection circuit included in the PFC hardware circuit.

[0068] Step 120, executing the test process to obtain the test result, the test result is used to reflect whether there is any hardware-related problem in the PFC hardware circuit.

[0069] In some embodiments, a PFC (Power Factor Correction) hardware circuit may be provided in an electronic device to improve the efficiency of the electronic device in utilizing electric energy. In some embodiments, the electronic device may be an air conditioning device, such as a variable frequency air conditioner, or an air conditioner with an IFD (Intense Field Dielectric) function.

[0070] In some embodiments, the test instruction may be received in a variety of ways. For example, taking an air conditioner as an example, the test instruction may be received by communicating with an application of a terminal device through an air conditioner external unit board. The terminal device may include a mobile phone, a tablet computer, or an air conditioner remote control device.

[0071] In some embodiments, the PFC hardware circuit may include at least a current sampling circuit and a demagnetization protection circuit. In some embodiments, the current sampling circuit may be used to collect the PFC current of the PFC hardware circuit, and the output voltage of the current sampling circuit may refer to the bias voltage of the current sampling circuit.

[0072] In some embodiments, the demagnetization protection circuit may be a protection circuit included in a PFC hardware circuit, which is used to prevent the devices connected to the PFC hardware circuit from being demagnetized under high current conditions. For example, taking a PFC hardware circuit provided in an air-conditioning device as an example, the demagnetization protection circuit may be used to trigger the demagnetization protection circuit when the PFC current of the PFC hardware circuit exceeds a preset demagnetization protection value, so as to prevent the compressor connected to the PFC hardware circuit from being demagnetized. The demagnetization protection value may be specifically determined according to actual conditions, for example, the demagnetization protection value may be 38A. The demagnetization protection circuit may prevent the compressor from being demagnetized, thereby avoiding performance degradation or damage to the compressor and ensuring the normal operation of the air conditioner.

[0073] It is understandable that the PFC hardware circuit may also include other circuits, for example, a voltage zero-crossing detection circuit and / or a voltage amplitude sampling circuit, etc., and correspondingly, the circuit may be tested by a corresponding test process in response to a received test instruction, and the present disclosure does not impose any restrictions on this. In some embodiments, when the test process includes multiple processes, the corresponding test processes may be executed according to the order of the received test instructions.

[0074] In some embodiments, the test results can be used to reflect whether there are hardware-related problems in the PFC hardware circuit, for example, whether there are hardware usage errors, incorrect demagnetization protection values, and whether the hardware connection relationship is correct. For specific details on executing the test process to obtain the test results, please refer to the following Figure 2 and 3 And the related description will not be repeated here.

[0075] The disclosed embodiment automatically executes the test process through the test instruction to verify the output voltage of the current sampling circuit included in the PFC hardware circuit and / or the demagnetization protection value of the demagnetization protection circuit included in the PFC hardware circuit, and obtains the test result reflecting whether there is a hardware-related problem in the PFC hardware circuit. The output voltage of the current sampling circuit included in the PFC hardware circuit and / or the demagnetization protection value of the demagnetization protection circuit included in the PFC hardware circuit are automatically verified through the test process, and the test result reflecting whether there is a hardware-related problem in the PFC hardware circuit can be accurately obtained, realizing the automatic verification of the accuracy of the PFC hardware circuit, improving the test efficiency and test accuracy, and the entire test process does not need to be completed manually, saving a lot of manpower and reducing the test cost. At the same time, the verification of the accuracy of the PFC hardware circuit through the output voltage and the demagnetization protection value is highly universal and applicable to the accuracy verification of all PFC hardware circuits.

[0076] Figure 2 FIG. 1 is a flowchart of executing a test process according to an exemplary embodiment. Figure 2 As shown, the process includes the following steps:

[0077] Step 210, obtaining the output voltage of the current sampling circuit.

[0078] Step 220 , determining whether the output voltage satisfies a first preset condition based on a preset voltage value and a first preset error margin.

[0079] Step 230: When the output voltage does not satisfy the first preset condition, a test result reflecting that a hardware usage error exists in the PFC hardware circuit is obtained.

[0080] In some embodiments, the first preset condition may be specifically determined according to actual conditions. For example, the first preset condition may be preset voltage value - first preset error margin < output voltage < preset voltage value + first preset error margin.

[0081] In some embodiments, based on a preset voltage value and a first preset error margin, determining whether the output voltage satisfies a first preset condition includes: subtracting the preset voltage value and the first preset error margin to obtain a first value, and summing the preset voltage value and the first preset error margin to obtain a second value; when the output voltage is less than the first value or greater than the second value, determining that the output voltage does not satisfy the first preset condition; and when the output voltage is greater than the first value and less than the second value, determining that the output voltage satisfies the first preset condition.

[0082] For example, when the first value is less than the output voltage and less than the second value, it is determined that the output voltage satisfies the first preset condition, the output voltage is correct, and a test result reflecting that there is no hardware usage error in the PFC hardware circuit is obtained; when the output voltage is less than the first value, or the output voltage is greater than the second value, it is determined that the output voltage does not satisfy the first preset condition, the output voltage is incorrect, and a test result reflecting that there is a hardware usage error in the PFC hardware circuit is obtained.

[0083] In some embodiments, the preset voltage value may be a standard bias voltage of the current sampling circuit, and the first preset error margin may be an allowable error value of the bias voltage. The preset voltage value and the first preset error margin may be specifically determined according to actual conditions, for example, the preset voltage value may be 2.27V, and the first preset error margin may be 0.25V.

[0084] In some embodiments, a hardware usage error may refer to damaged hardware and / or incorrect hardware parameters, for example, a damaged resistor or operational amplifier, a wrong resistor value or operational amplifier model, etc. In some embodiments, a hardware usage error in a PFC hardware circuit may refer to a hardware usage error in the PFC hardware circuit or a current sampling circuit included therein.

[0085] Figure 3 FIG. 1 is another flow chart showing a test process according to an exemplary embodiment. Figure 3 As shown, the process includes the following steps:

[0086] Step 310 , increasing the output current of the PFC hardware circuit to a demagnetization protection triggering value to start the hardware demagnetization protection function of the demagnetization protection circuit.

[0087] Step 320 , obtaining a current change of the output current after the hardware demagnetization protection function is started, and determining a current peak value in the current change.

[0088] Step 330 : determining whether the current peak value satisfies a second preset condition based on the demagnetization protection value and the second preset error margin.

[0089] Step 340: When the current peak value does not satisfy the second preset condition, a test result is obtained reflecting that the demagnetization protection value of the hardware in the PFC hardware circuit is incorrect.

[0090] In some embodiments, the PFC hardware circuit is further provided with a software demagnetization protection function, and the output current of the PFC hardware circuit is increased to trigger the demagnetization protection value, including: turning off the software demagnetization protection function, and increasing the output current of the PFC hardware circuit to trigger the demagnetization protection value. In some embodiments, the demagnetization protection value set by the software demagnetization protection function can be amplified by a preset multiple to turn off the software demagnetization protection function, for example, it can be amplified by 10 times. By turning off the software demagnetization protection function, the interference of the software demagnetization protection function on the hardware demagnetization protection function can be avoided, so as to facilitate the subsequent accurate verification of whether the demagnetization protection value of the hardware demagnetization protection circuit is correct.

[0091] In some embodiments, increasing the output current of the PFC hardware circuit to trigger the demagnetization protection value includes: increasing the inductance parameter included in the PFC hardware circuit by a preset multiple to increase the output current of the PFC hardware circuit to trigger the demagnetization protection value. The preset multiple can be specifically determined according to actual conditions, and the preset multiple can be 8-10 times, for example, the preset multiple can be 10 times. By increasing the inductance parameter included in the PFC hardware circuit by a preset multiple, the PFC hardware circuit can be abnormal after startup, so as to increase the output current of the PFC hardware circuit, trigger the demagnetization protection value, and then start the hardware demagnetization protection function of the demagnetization protection circuit.

[0092] In some embodiments, the second preset condition may be specifically determined according to actual conditions. For example, the second preset condition may be demagnetization protection value - second preset error margin < output voltage < demagnetization protection value + second preset error margin.

[0093] In some embodiments, based on the demagnetization protection value and the second preset error margin, determining whether the current peak meets the second preset condition includes: subtracting the demagnetization protection value and the second preset error margin to obtain a third value, and summing the demagnetization protection value and the second preset error margin to obtain a fourth value; when the current peak is less than the third value or greater than the fourth value, determining that the current peak does not meet the second preset condition.

[0094] For example, when the third value is less than the current peak value and less than the fourth value, it is determined that the current peak value satisfies the second preset condition, the demagnetization protection value is correct, and a test result is obtained reflecting that the demagnetization protection value is incorrect and that there is no hardware in the PFC hardware circuit; when the current peak value is less than the third value, or the current peak value is greater than the fourth value, it is determined that the current peak value does not satisfy the second preset condition, the demagnetization protection value is incorrect, and a test result is obtained reflecting that the demagnetization protection value is incorrect and that there is hardware in the PFC hardware circuit.

[0095] In some embodiments, the incorrect demagnetization protection value of the hardware may refer to an incorrect demagnetization protection value of a demagnetization protection circuit included in the PFC hardware circuit. For example, taking the demagnetization protection circuit as an example for performing demagnetization protection on a compressor connected to the PFC hardware circuit, the incorrect demagnetization protection value of the hardware may refer to an incorrect demagnetization protection value of the compressor.

[0096] In some embodiments, different demagnetization protection values ​​may be set according to different active devices of the demagnetization protection circuit. For example, taking the active device as a compressor as an example, the demagnetization protection value may be 38A. In some embodiments, the second preset error margin may be an allowable error value of the demagnetization protection value, and the second preset error margin may be specifically determined according to actual conditions, for example, the second preset error margin may be 3A.
