Abstract :
The efficient modeling of unijunction transistor (UJT) is an burning issue in power industries. The available SPICE based model provides V-I characteristic of UJT. The output characteristic of UJT is nonlinear in nature and its modeling plays an important role in many applications where the output voltage of UJT drives any other device or circuit. In this paper a nonlinear device model is proposed using functional link artificial neural network (FLANN) and adaptive finite impulse response (FIR) filter along with artificial immune system (AIS) for simulation of UJT. The potential of the proposed model is demonstrated for modeling of both the V-I and output characteristics of UJT under variable load conditions.
