description: Topic of the final qualification work- "Development and investigation of a model of a sinusoidal pulse-width modulation rectifier". The purpose of the work is to develop the control program code for the operation of a PWM rectifier. The primary task is to correct the nonlinearity of the input signal. PWM rectifiers are devices that convert alternating current (AC) into direct current (DC) with minimal energy loss. They are used in applications where not only the type of electricity needs to be changed but also its quality needs improvement. For example, such devices make the electrical grid more stable and efficient: they reduce energy losses, minimize interference, and extend equipment lifespan. In the context of "smart grids," things are more complex. These grids require all devices in the system to operate in harmony. For instance, during peak load hours, energy must be redistributed quickly to avoid overloads. This is achieved using artificial intelligence technologies that instantly analyze data and manage the grid. Such technologies also facilitate the integration of local microgrids with the main system and optimize the use of energy storage devices. Now, regarding how to create an electrical signal of the required shape, there are two approaches Simple method (ideal sine through conversion)- in this approach, alternating current is first converted into direct current and then back into alternating current, but with a perfect sine wave shape. Here, the input signals form does not matterâ the output always produces a clean, distortion-free sine wave. This method is easier to implement, but in practice, an additional system is still needed to correct minor errors. Complex method (correcting the input signal)- in this approach, the input signal is analyzed, and the device "corrects" it to make it ideal. This is achieved through a special method of analysisâsignal decomposition into components. The system monitors distortions, calculates how to eliminate them, and performs all corrections in real-time. The second approach is more complex as it requires precise measurements, computations, and continuous feedback. This method involves using a PID controller to handle inaccuracies and stabilize the system. The controller takes into account how the device responds and gradually adjusts actions to achieve optimal results. In real projects, the second approach is more commonly implemented but simplified to process data faster. This enables real-time signal handling without delays. In the project code, the second approach is implemented but without Fourier transformation. This allows the signal to be processed instantly without lagging by half a period or averaging over multiple cycles. The program generates the signal in real time.
