Control of the Pulse Converter in Case the Presence of Input Perturbations and Current Overloads in the Output Circuit : In memory of the professor of the Department of physical and biomedical electronics NTU "KhPI" Yuri Petrovich Goncharov
The original technical solutions for the implementation of a microprocessor control system for a DC/DC converter are proposed in the paper. The effectiveness of such solutions has been proven by using the developed mathematical model. Input perturbations are considered in the form of single jumps of the input voltage or its deviation from a certain constant value. It is shown that to compensate such disturbances, it is sufficient to clock the digital pulse-width modulator with impulses, the repetition rate of which is proportional to the input voltage of the converter.Additionally, it is possible to implement an automatic restart in the event of short-term overcurrent in the output circuit of the converter by reducing the modulation frequency of the input signal.
