The aero-engine gas path fault is the important aero-engine fault and has high frequency. This fault must be found timely and solved as early as possible to make sure the normal work of aero-engine and the safe flight of the airplane. The burn fragments fault is a common fault aero-engine gas path fault. The special aero-engine gas path fault simulation test system is necessary if we want to study...
This paper proposed a novel topology and control strategies for AC solid state power controllers (SSPC) in order to improve its capacity for starting large capacitive loads and enhance the security during short-circuit protection in high-power applications.
The wide application of same-tower transmission lines has brought new challenges to fault analysis and relay protection operation in power system. In this paper, the diversity of construction form of same-tower transmission lines is introduced. And its operation characteristics, such as strong magnetic coupling and easy occurrence of inter-line fault, are analyzed. Then the influence of same-tower...
The quantitative descriptions of fault responses' characters are the chiefly presupposition of circuit fault analysis and diagnosis. Aimed to solving the deficiency of traditional information entropy theory in characters extraction of the information mutation, an energy based information entropy model is proposed to measure the complexity feature of signals. Firstly, the energy distribution uncertainty...
In this paper, we propose a new BIST method for analog and mixed-signal circuits test based on pseudorandom testing. Firstly we use pseudo-random sequence as testing stimulus, and we can obtain K-dimensional signature space by calculating the cross-correlation function of input and output sequences. Secondly, we can analyze and diagnosis the circuits under test (CUT) by signatures in the signature...
