[0062] In a preferred embodiment, the obtaining of the application device category of the high-voltage output switching power supply includes:

[0063] Identifying a device keyword from a design database of the high-voltage output switching power supply;

[0064] According to the equipment keywords, the application equipment of the high-voltage output switching power supply is classified into industrial automation equipment, communication equipment, household electrical appliances, medical equipment, and new energy battery charging equipment.

[0065] Specifically applied to the embodiments of the present invention, the device keywords can also be identified through the design database to obtain the category of the application equipment of each high-voltage output switching power supply. For example, when the design database retrieves keywords such as "automation", "robot", "production", and "monitoring", the application equipment corresponding to the high-voltage output switching power supply is classified as industrial automation equipment.

[0070] The current or voltage thresholds corresponding to each category of equipment are different. Adding the equipment category as an influencing factor helps to improve the accuracy of the current or voltage threshold switching soft or hard switch.

[0071] Step S103: query the load electrical threshold of the application device category.

[0072] In actual application to the embodiment of the present invention, the initial load electrical threshold of the application equipment category can also be obtained, that is, in the embodiment of the present invention, the correspondence between the industrial automation equipment category, communication equipment category, household electrical appliance category, medical equipment category, and new energy battery charging equipment category and the initial load electrical threshold can be pre-set.

[0073] For example, the initial load electrical threshold corresponding to the automation equipment class C1 is M1, and the corresponding relationship between the two is {C1, M1}; the initial load electrical threshold corresponding to the communication equipment class C2 is M2, and the corresponding relationship between the two is {C2, M2}; the initial load electrical threshold corresponding to the household appliance class C3 is M3, and the corresponding relationship between the two is {C3, M3}; the initial load electrical threshold corresponding to the medical equipment class C4 is M4, and the corresponding relationship between the two is {C4, M4}; the initial load electrical threshold corresponding to the new energy battery charging equipment class C5 is M1, and the corresponding relationship between the two is {C5, M5}.

[0076] According to the industrial automation equipment category, communication equipment category, household electrical appliances category, medical equipment category, and new energy battery charging equipment category, the corresponding initial load electrical threshold is queried;

[0077] The initial load electrical threshold is determined to be the load electrical threshold for the application equipment category.

[0078] In an embodiment of the present invention, the codes C1, C2, C3, C4, and C5 of the application device category can be first obtained; based on the correspondence between the application device category and the initial load electrical threshold, M1 or M2 or M3 or M4 or M5 can be obtained; it should be noted that the load electrical threshold refers to the current threshold or voltage threshold for controlling the switching of soft switching devices and hard switching devices.

[0079] Step S104: Correct the load electrical threshold according to the circuit type ratio to obtain a corrected load electrical threshold.

[0082] First, the correction coefficient of the circuit type ratio can be calculated, and then the upper limit and lower limit of the load electrical threshold are obtained according to the correction coefficient, and the load electrical threshold is combined with the upper limit and lower limit to obtain the corrected load electrical threshold.

[0083] Specifically applied to the embodiment of the present invention, the expression of the correction coefficient is as follows:

[0084]

[0085] Among them, t represents the correction coefficient, u represents the rated voltage of the system, L represents the load power of the system, b represents the number of circuit types of the high-voltage output switching power supply, n represents the proportion of each circuit type, i=1, 2, 3...b; λ represents the line impedance of the system; the upper limit and lower limit of the load electrical threshold can be obtained according to the correction coefficient, that is, the upper limit is +t, and the lower limit is -t. For example, the corrected load electrical threshold is M1 ±t, that is, (M1-t, M1+t).

[0086] It should be noted that the above-mentioned correction method for the load electrical threshold is only an example of an embodiment of the present invention. The load electrical threshold can also be corrected in other ways, and the embodiment of the present invention does not impose too many restrictions on this.

[0087] Step S105: Control switching of the soft switch device or the hard switch device according to the corrected load electrical threshold value to obtain corresponding test parameters.

[0088] Specifically applied to the embodiment of the present invention, after obtaining the corrected load electrical threshold, the electrical parameters such as current and voltage of the test system can be detected, and the relationship between the electrical parameters such as current and voltage and the load electrical threshold can be determined, so as to control the switching of soft switching devices or hard switching devices and output corresponding test parameters; wherein, the test parameters may include a plurality of preset parameters representing the safety and durability of the equipment, and the embodiment of the present invention does not impose excessive restrictions on this.

[0089] In actual applications, the soft switching device or the hard switching device is switched according to the corrected load electrical threshold control to obtain corresponding test parameters, including: when the electrical parameter of the high-voltage output switching power supply is less than the load electrical threshold, the control is switched to the soft switching device for testing to obtain the first test parameter; when the electrical parameter of the high-voltage output switching power supply is greater than the load electrical threshold, the control is switched to the hard switching device for testing to obtain the second test parameter.

[0090] In an embodiment of the present invention, the automatic testing method of the high-voltage output switching power supply includes: obtaining the circuit type ratio of the high-voltage output switching power supply; obtaining the application equipment category of the high-voltage output switching power supply; querying the load electrical threshold of the application equipment category; correcting the load electrical threshold by the circuit type ratio to obtain the corrected load electrical threshold; controlling the switching of soft switching devices or hard switching devices according to the corrected load electrical threshold to obtain corresponding test parameters, and according to the electrical device composition of the high-voltage output switching power supply itself (internal factors) and the equipment used by the high-voltage output switching power supply (external factors), the two are combined to obtain the switching control threshold, so that the timing of switching the soft switch or the hard switch is determined by the comprehensive electrical characteristics and equipment characteristics, thereby improving the accuracy of the switching power supply control, improving the accuracy of the simulation test, solving the problem of how to test the high-voltage switching power supply of the dual-switch type, and being suitable for testing of various application scenarios.
