Sažetak
Accurate description of thermo-electric systems and their behaviour during transient represents a demanding task. Because of high nonlinearity of elements in such system and if linearization cannot be done during transient, corresponding differential equation(s) are also nonlinear. Development of personal computers (PCs) and the reduction of their price, provide application of the numerical techniques and procedures for solving such nonlinear systems instead of the analytical solving techniques. However, knowing of analytical expression(s) which describes behaviour of nonlinear system during the transient is beneficial. In this article development of minimum correct transient thermo-electric model of incandescent lamp is described in detail. Procedure for obtaining analytical solution with exact solution which describes behaviour of incandescent lamp during the transient is shown. Obtained analytical solution and presented model are verified with numerical solution of non approximated nonlinear differential equation and measurement results. The application of presented thermo-electric model for description transient behaviour of incandescent lamp is shown on obtaining inrush current of well known H7 car light bulb. Presented thermo-electric model and its analytical solution are also applicable for determining inrush current of all incandescent lamps and infrared heaters.
