A simpleequivalentcircuit model of quantum well laser (QW LD) which is derived by QW rate equations and is accomplished in the circuit simulation program SPICE.
This paper presents a transient mathematical model of the HVDC converters-EquivalentCircuit Method (ECM), which can describe all possible states of converter valves in a simple and explicit way.
A simple method is devised for measuring the detection impedance in the acoustic impedance method of detection of unbonds and is based on an equivalentcircuit of the detector.
