5 14 Institute of the Fifth Academy of Aerospace Science and Technology developed a brand-new power resistance testing device.




As the first-class metering station of national defense science, technology and industry electricity, 514 newly-developed DC power supply system impedance testing devices in the Fifth Academy of China Aerospace Science and Technology Corporation have completed the test from


Theoretical research and practical application, as well as all-round development from measuring methods to measuring instruments, from physical quantity definition to measurement standards, from standards and specifications to technical indicators, have been supplemented.


Domestic blank.


Foreign spacecraft have widely used power supply impedance as a technical index to evaluate the performance of power supply system, and internationally renowned power supply manufacturers have been in the technical parameters of DC power supply products


The power supply impedance is required in the number. However, China's power supply manufacturers have not given such parameters.


In order to solve this problem, the institute researched and developed a calibration device. Support the periodic calibration of new parameters, and also develop related application software to provide the stability of power system.


Qualitative design simulation, popularize the application of new parameters.


The project has formed the core technology and invention patents with independent intellectual property rights, revised the existing technical specifications and calibration specifications of DC power supply products, and revised the new parameters.


Measurement and calibration also produced devices and standards with independent intellectual property rights, which promoted the technical update of DC power products.
