description: In this bachelors thesis, a control device was developed for a single-phase low-frequency inverter, which allows issuing control signals for transistors that provide a rectangular-step voltage of the âmodified sine waveâ type at the output of the converter. The main feature of the development, which should replace the existing control device, is the presence of a special algorithm for limiting the output current, which allows you to charge the capacitance of devices connected to the load, but at the same time ensures a limitation of the switching frequency of transistors. The need for development is caused by the desire to modernize existing converters in such a way that the consumer has the opportunity to connect rectifier-capacitive ones as a load, a striking example of which are switching power supplies. An additional bonus, since it is rational to solve this problem on a microcontroller, is the ability to organize data transmission channels, both with other boards as part of the product, and with a computer during setup. The practical significance of the work is that the results obtained can be used in the construction of not only single-phase, but also three-phase voltage inverters, and the proposed algorithm for measuring the output voltage can be of interest in all cases of developing a similar class of devices. We can also note the possibility of continuing this work in the form of research into the influence of circuit parameters and connected loads on the quality indicators of power supply to consumers.
