[0025] The first embodiment of a power supply protection method of the present application will be described in detail below.

[0026] The power supply device in the first embodiment of the present application includes a power supply 11, a controller 12, a first power module 13, a second power module 14, and a chip carrier board 15.

[0027] In the embodiment, the power supply 11 is a 12V power supply, and the power supply 11 is connected with the input ends of the first power supply module 13 and the second power supply module 14. It can be understood that the first power supply module 13 and the second power supply module 14 are parallel in circuit, and thus the voltages of the first power supply module 13 and the second power supply module 14 are consistent with the voltage of the power supply 11, which is 10V.

[0029] Preferably, the power supply 11 is a 48V power supply. Replacing the 12V power supply 11 with a 48V power supply can reduce the power loss caused by the device cable and thus reduce the requirement of the device on the cable.

[0031] In the embodiment, the output ends of the first power supply module 13 and the second power supply module 14 are connected with the chip carrier 15 to supply power to the chip carrier 15. It can be understood that the whole of the first power supply module 13 and the second power supply module 14 in parallel is connected in series with the chip carrier 15, and thus when the first power supply module 13 and the second power supply module 14 supply power to the chip carrier 15 at the same time, the current of the chip carrier 15 is the sum of the currents of the first power supply module 13 and the second power supply module 14. It can be understood that the chip carrier 15 can be connected with a chip, and the chip can be various chips to be tested, and the currents required for the normal operation of various chips are different. For example, the current required for the normal operation of a chip A is 8A, and thus the power supply device in the embodiment can be used to supply power, and only one of the first power supply module 13 or the second power supply module 14 is used to supply power to the chip carrier 15, which can meet the requirement of the normal operation of the chip A. The current required for the normal operation of a chip B is 16A, and thus the first power supply module 13 and the second power supply module 14 can be used to supply power to the chip carrier 15 at the same time, which can meet the requirement of the normal operation of the chip B.

[0032] In the embodiment, the controller 12 is connected with the power supply 11 to control the on-off of the power supply 11, and the controller 12 is also connected with the first power supply module 13 and the second power supply module 14 respectively to control the on-off of the first power supply module 13 and the second power supply module 14 respectively, so as to control the current provided to the chip carrier 15.

[0035] In other embodiments, there are multiple chip carrier boards 15 and multiple power modules, and each chip carrier board 15 is connected with multiple power modules. For example, there are 5 chip carrier boards 15 and a total of 30 power modules, and each chip carrier board 15 is connected with 6 power modules, and each power module is connected with the controller 12, and the controller 12 can control each power module to supply power to the chip carrier board 15 connected therewith, so as to provide various different currents for the chip carrier board 15, and meet the power supply requirements of various chips for normal operation, so as to better complete the test of the chips.

[0036] Referring to Figure 2 , Figure 2 is a structural schematic diagram of a second embodiment of the power supply device of the present application.

[0037] The second embodiment of the power supply device of the present application is described in detail below.

[0038] In this embodiment, the power supply device comprises a power supply 21, a power supply adapter 211, a controller 22, a first power module 23, a second power module 24, a chip carrier board 25, an overvoltage module 251, an overcurrent module 252, a temperature control module 26, a motor module 27, an acquisition module 28, and an alarm module 29.

[0039] In this embodiment, the power supply 21 is a 220V alternating current power supply, and the power supply 21 is connected with the input ends of the first power module 23 and the second power module 24 through the power supply adapter 211, and the power supply adapter 211 can convert the voltage of 220V of the power supply 21 into a voltage of 48V. The same as the first embodiment of the present application is that the first power module 23 and the second power module 24 are connected in parallel, and the voltages provided by the first power module 23 and the second power module 24 are consistent with the voltage converted by the power supply adapter 211, which is 48V. It can be understood that the controller 22 can control the first power module 23 and the second power module 24 to supply power to the chip carrier board 25 to make the chip carrier board 25 obtain a current of 8A or 16A to meet the current required by different chips for normal operation.

[0040] In the embodiment, the chip carrier 25 is also connected with an overvoltage module 251 and an overcurrent module 252. The overvoltage module 251 can detect the voltage of the chip carrier 25, so as to cut off the power supply of the chip carrier 25 when the voltage of the chip carrier 25 is abnormal, thereby protecting the chip from being burnt. The overcurrent module 252 can detect the current of the chip carrier 25, so as to cut off the power supply of the chip carrier 25 when the current of the chip carrier 25 is abnormal, thereby protecting the chip from being burnt. It can be understood that the overvoltage module 251 and the overcurrent module 252 can effectively protect the operation of the chip and the chip carrier 25, thereby increasing the safety of the power supply device.

[0041] In the embodiment, the power supply 21 and the controller 22 are also connected with a temperature control module 26 and a motor module 27.

The motor module 27 can control the temperature of the environment where the chip carrier 25 is located, thereby providing corresponding temperature conditions for testing the performance of the chip. It can be understood that the temperature control module 26 can cooperate with the motor module 27 to complete the temperature control at the chip carrier 25, thereby completing the corresponding chip test.

The alarm module 29 can issue an alarm to remind the abnormal working of the equipment. It can be understood that the controller 22 judges after receiving the data information collected by the collection module 28. If it is determined that the chip carrier 25 works abnormally, the controller 22 controls the alarm module 29 to issue an alarm, thereby playing a role of reminding the staff, and further increasing the safety and reliability of the equipment.

[0043] Referring to Figure 3 , Figure 3 is a structural schematic view of a third embodiment of the power supply device.

[0047] In the embodiment, the power supply 31 is a 220V alternating current power supply, and is used for supplying power to the test computer 311, the switch 312, the controller 32, the power adapter 321, the temperature control module 36, the motor module 37, the acquisition module 38 and the alarm module 39.

When the controller 32 is powered on, the controller 32 starts a self-checking program to detect faults of each module.

[0049] Please refer to Figure 4 , Figure 4 which is a flowchart of the first embodiment of the power supply control method of the application.

[0050] The first embodiment of the power supply control method of the application is described in detail below.

[0051] S410: receiving the required current of the chip carrier.

[0052] In the embodiment, the different chips arranged on each chip carrier cause different required currents, so the required current of the chip on each chip carrier is required, and the required current of the chip carrier is the voltage that can enable the chip to work normally.

[0053] S420: according to the required current, analyzing the expected number of power supply modules required to be connected in parallel for each chip carrier, and sending a parallel instruction containing the expected number information through the controller.

[0054] In the embodiment, the required current of each chip carrier is different, and the number of power modules required for power supply is different. Each chip carrier corresponds to a plurality of power modules. The voltage of each power module is the same, and the current that can be provided is also the same. Therefore, the number of power modules required can be calculated according to the current required by each chip carrier. The controller sends a parallel instruction with the number of power modules required in parallel to make the corresponding number of power modules in parallel to supply power to the chip carrier.

[0055] S430: In response to the parallel instruction of the controller, turn on the expected number of power modules in parallel to supply power to the chip carrier.

[0056] In the embodiment, the corresponding number of power modules in the parallel instruction is connected in parallel to the corresponding chip carrier by the parallel instruction sent by the controller to supply power to the chip carrier, so that the chips connected to the chip carrier work normally.

[0057] In other embodiments, the step S430 further includes: collecting the voltage and / or current of the chip carrier; determining whether the voltage and / or current of the chip carrier is abnormal; in response to the abnormal voltage and / or current of the chip carrier, disconnecting the power module connected to the chip carrier; and sending alarm information of the abnormal voltage and / or current of the chip carrier to the controller. By collecting the voltage or current at the chip carrier and determining whether the voltage or current of the chip carrier is abnormal, that is, whether it is greater than a preset value. If the voltage or current is abnormal, each power module that is abnormal is disconnected from the corresponding chip carrier, which can effectively protect the safety of the chip carrier and the chip. The voltage and current at the chip carrier can also be collected at the same time. As long as any one of them is greater than the preset value, the connection between the chip carrier and the corresponding power module is disconnected. After disconnecting the chip carrier and the corresponding power module, an alarm information is sent.

[0058] In other embodiments, before step S410, it further includes: collecting self-checking information of the controller; determining whether the self-checking information of the controller is abnormal; in response to the abnormal self-checking information of the controller, disconnecting the power supply; and in response to the normal self-checking information of the controller, supplying power to the power module. Before supplying power to the chip carrier, the controller is supplied with first-level power. The controller performs self-checking and determines whether there is a device failure in the self-checking information. If the self-checking information shows that there is a device failure, the power supply is disconnected and the power module is not supplied with second-level power. If the self-checking information shows that there is no device failure, the power module is supplied with second-level power.
