Моделювання резонансного генератора імпульсів на основі діода в системі формування наносекундних сигналів

Abstract

The paper presents an approach to studying the processes of nanosecond pulse formation in the system of electromagnetic disinfection of grain mass based on the development of a generalized mathematical model. The model structure is proposed in the form of interconnected functional blocks that reproduce the operation of a real installation, in particular the processes of input signal formation, its transformation in a resonant generator based on a nonlinear semiconductor diode and the generation of pulses of nanosecond duration. The paper uses methods of the theory of electrical circuits, mathematical and numerical modeling, and spectral analysis of signals using the Fourier transform, which allowed us to study the time and energy characteristics of pulses. Particular attention is paid to taking into account the nonlinear properties of the diode and their influence on the shape, duration, and spectrum of the signal. The proposed model provides the possibility of a comprehensive analysis of the processes of generation, transmission, and conversion of pulses, and can also be used as a theoretical basis for optimizing the parameters of systems of electromagnetic disinfection of grain products.
