Along with the high growth demand for the functions of the phased array antenna system, its complexity and integration degree have become higher and higher, the development cost has shown a rapid increase, and the reliability problem of the entire phased array antenna system has become more and more prominent. Therefore, it has become more and more important to conduct reliability tests on the phased array antenna system, evaluate the reliability level of the system, find the factors affecting the system reliability, and rapidly enhance the reliability of the entire system. As an electronic product, the stability and reliability of the power supply are the most critical and core elements to ensure the normal operation of the system.

[0050] The following will, with reference to the drawings, elaborate on some embodiments of the present application. Without conflict, the following embodiments and the features in the embodiments may be combined with each other.

[0051] Existing power reliability verification test methods usually conduct special power verification tests through professional EMC laboratories. However, as a professional laboratory, an EMC laboratory is relatively expensive, and as a scarce professional resource, each test requires advance reservation and connection of resources, which takes a lot of time. For the routine power reliability special verification in the R & D stage, it is not very applicable. Or expensive professional power instruments are purchased to achieve various verifications of the power supply. Since such professional instruments are relatively expensive in themselves and are also targeted special test instruments, if comprehensive power verification needs to be completed, multiple test instruments need to be purchased, which is costly and has low effective utilization rate.

[0052] To overcome the above problems, an embodiment of the present application provides a phased array antenna power supply simulation system 10, which can be used to detect the power reliability of the phased array antenna.

[0053] Please refer Figure 1 , the phased array antenna power supply simulation system 10 includes a controller 101, a power supply module 102, a linear switch module 103, and an energy storage module 104. The controller 101 is respectively connected to the control end of the power supply module 102 and the control end of the linear switch module 103. The input end of the linear switch module 103 is connected to the output end of the power supply module 102, and the output end of the linear switch module 103 is connected to the input end of the phased array antenna 20. One end of the energy storage module 104 is connected between the linear switch module 103 and the input end of the phased array antenna 20, and the other end of the energy storage module 104 is connected to the negative end of the phased array antenna 20 or grounded.

[0054] The controller 101 is used to send a voltage command to the power supply module 102 and is also used to send a driving voltage to the linear switch module 103 according to a preset linearity.

[0055] Among them, the linearity is the change speed of the driving voltage. Possibly, the change speed includes an increasing speed and / or a decreasing speed.

[0056] The power supply module 102 is used to output a voltage corresponding to the voltage command after receiving the voltage command.

[0057] The linear switch module 103 is used to switch to an opening degree corresponding to the driving voltage after receiving the driving voltage.

[0058] Among them, under the condition that the input voltage remains unchanged, the opening degree is positively correlated with the magnitude of the current flowing through the linear switch module 103. Possibly, the opening degree can be understood as the saturation degree. Under the condition that the input voltage remains unchanged, when the saturation degree is larger, the current flowing through the linear switch module 103 is larger.

[0059] The energy storage module 104 is used to cache and supply energy for the phased array antenna 20.

[0060] Optionally, the controller 101 can adjust the output voltage of the power supply module 102 by changing the voltage command. The controller 101 can also adjust the opening degree of the linear switch module 103 by changing the driving voltage, change the current flowing through the linear switch module 103, and change the voltage loaded on the load - phased array antenna 20. Therefore, the controller 101 can simulate various working conditions corresponding to the power supply system of the phased array antenna 20 by adjusting the voltage command and the driving voltage.

[0061] In summary, in the phased array antenna power supply simulation system provided by the embodiments of the present application, the phased array antenna power supply simulation system includes: a controller, a power supply module, a linear switch module, and an energy storage module. The controller is respectively connected to the control end of the power supply module and the control end of the linear switch module. The input end of the linear switch module is connected to the output end of the power supply module. The output end of the linear switch module is connected to the input end of the phased array antenna.

[0063] The collection module 105 is used to collect the current voltage loaded on the phased array antenna 20 and transmit the current voltage to the controller 101.

[0064] The controller 101 adjusts the linearity according to the current voltage so that the current voltage changes according to a preset slope.

[0065] Optionally, after receiving the current voltage, the controller 101 determines whether the current voltage of the phased array antenna 20 matches the current output voltage command and driving voltage of the controller 101; if not, the linearity corresponding to the driving voltage needs to be changed to make it match; if it matches, no adjustment is required.

[0066] Optionally, the controller 101 determines a matching value based on the currently output voltage command and the driving voltage, compares the current voltage of the phased array antenna 20 with the matching value, and determines that they do not match if the difference is greater than a preset threshold.
