The main content of logic circuit fault detection includes describing circuit to be diagnosed, determining fault and circuit initial information, generating circuit location test set. In this study, LASAR is used to carry out the logic circuit simulation so as to create such documents as fault dictionary, node truth value table, etc. for the preparation of fault detection. Due to the limitation...

When test vectors are applied to a circuit, the fault coverage increases. The rate of increase, however, could be circuit-dependent. In fact, the actual rise of fault coverage depends on the characteristics of vectors, as well as, on the circuit. The paper shows that the average fault coverage can be computed kom circuit testability. A relationship between fault coverage and circuit testability...

A switched capacitor circuit which simulates Frequency Dependant Negative Resistor is proposed. The circuit is controlled by three phases clock and needs one unity gain buffer. A comparison among SC FDNRs in other references is shown. SWITCAP simulation of SC filter using these circuits are also shown. Key-Words; Switched-Capacitor(SC) Frequency Dependant Negative Resistor(FDNR) Filter immittan...

The Sen Transformer (ST) provides an economical solution for power flow control and voltage regulation. However, fault analysis evaluation of the performance transmission protection system in presence a ST have not been investigated. Hence, short-circuit model using phase coordinate method is proposed this paper. Firstly, according to coupled-circuit model, nodal admittance matrix between sendi...

Temporary overvoltage (TOV) is becoming one challenge for the integration of significant power electronics resources into a system. To assess risk TOV in Multi-Infeed Power Electronic System (MIPES), worst-case estimation approach proposed to risk. The paper starts with analyzing mechanism TOV, which reveals that dominated by excessive reactive resulting from comprehensive control laggings. The...
