A New Pulse Shift Method of DC Bus Current Detection for Driving with a Low Modulation Factor

Abstract Lock-in IR-OBIRCH analysis, as a kind of static thermal laser stimulation (S-TLS) technique, is very effective to isolate a fault for the parametric failure cases. However, its capability is limited to localize a defect when the IC is operated under a defined operating condition. Whereas the dynamic thermal laser stimulation (D-TLS) technique is good at locating a fault while the IC is operated under some functions to activate the failure. In this paper, a novel method is presented to realize DTLS just by Lock-in IR-OBIRCH assisted with a Current Detection Probe Head. Two cases are studied to demonstrate the effectiveness of this method.

Current Detection

In spite of the increased use of streaming current detectors (SCDs) as a means of monitoring and/or controlling coagulant dosage, knowledge regarding fundamental workings is incomplete. This paper provides an initial attempt at predicting and verifying functioning compared to electrophoretic mobility. The instrument's components -- the sensor and the signal processor -- are first described. Equations modelling electro-double layer behavior in its sensor are then developed. Simplifying assumptions include the use of a capacitance model of the double layer and a triangular velocity profile for fluid within the sensor's annulus. More complex modelling approaches are also suggested which incorporate the Gouy-Chapman electro-double layer model and an exact solution for the velocity profile. Experimental results confirm predictions of the simplified model under conditions of low potential. A monotonic relationship exists between streaming current electrophoretic mobility, which is required for its use as a control parameter. Deviations from model predictions are suggested to be due to charge characteristics of the sensor surfaces themselves.
