Abstract

The invention discloses a power supply test platform system applied to a testability verification test. According to the technical scheme provided by the invention, the system has medium-high frequency alternating current output, high voltage direct current output, AC / DC resistive load output and high-power switching capacities. Not only a single piece of equipment can be operated, but also the outputs of multiple pieces of equipment can be controlled via software. Therefore, high power is achieved, medium-high frequency is covered, and the effects of multiple fault injection means, and beingsafe and reliable, and controllable in injection process are achieved. The requirement of simulating power fault injection during the testability experimental process can be met.

Description

technical field [0001] The invention relates to a power supply test platform system used for testability verification tests, and belongs to the technical field of testability verification. Background technique [0002] Built-in test, BIT technology is the comprehensive ability of the system or equipment to rely on its internal detection circuit and detection software to complete system or equipment working parameter monitoring, fault detection and isolation. [0003] Pitfalls and Risks of Power Fault Injection Techniques. In the process of product testability verification test, the hardware fault injection technology is adopted. In view of the particularity of the power module of the equipment, hardware fault injection has a greater risk and is not easy to operate. It is very likely to cause damage to the equipment, resulting in equipment failure. The testability verification test failed. [0004] The means of injecting power faults in current testability experiments are v...
