Integrated development of software and hardware components of the frequency converter filter for operating in power-limited ship networks

Complex energy systems use a large number of different consumers with a non-linear load. Most of them are complex technical and expensive devices. Due to the non-linearity of the load of these consumers, electromagnetic interference occurs in the network, which negatively affects the correct operation of such equipment. Due to the impact of electromagnetic interference on the operation of complex technical equipment operating in large power systems, a decrease in the quality of signals and power, as well as a noticeable decrease in the service life of devices affected by interference, can occur. In frequency converters, due to electromagnetic interference in low-current control signals of power elements, there is a possibility of a short circuit, which will lead to a complete failure of the device. To reduce the effect of electromagnetic interference on devices, passive or active filtering is often used. This article discusses the development and design of an experimental sample of an active filter to use in low-current circuits of frequency converters, as well as the development of an algorithm for the operation of an active filter control system. The research method is to review existing solutions in order to understand how the algorithms are implemented on other devices. The control system, the algorithm was developed for, is implemented on the debugging platform STM32F411E-DISCO. Such solution will make it possible to meet all the emerging needs that arise during the implementation of the active filter device. The creation of the operation algorithm for this filter was carried out in the MATLAB software package. Due to this solution, it becomes possible to create an operation algorithm without additional difficulties associated with the further translation of the algorithm into C++ code loaded into the microcontroller.
