In order to identify the best control algorithm, the effects of modulation control algorithms on the energy characteristics of a two-level autonomous frequency converter inverter were studied. The research was carried out by the methods of mathematical and simulation modeling. The equa-tions of mathematical description were compiled taking into account a number of generally accepted assumptions. An equivalent circuit of a two-level autonomous inverter was created. Comparisons of pulse-width modulation algorithms with carrier signals of various shapes and frequencies were made. Three different forms of carrier signal were used: triangular, sawtooth with a falling edge and sawtooth with a leading edge. Studies were conducted at frequencies of 3,000, 6,000 and 9,000 Hz. Conclusions were made about the identity of the spectral composition of the front and rear edges of the sawtooth signal, it was also noted that with the triangular waveform, being the part of the har-monics, present in the sawtooth form is removed, so, the triangular shape provides the best result of the autonomous inverter. Also, by increasing in the carrier frequency, it was noted that pulse packets appear at different harmonic numbers, shift, and the amplitude and distortion factor decrease, that means, the best performance was obtained at the maximum frequency studied. In the study of the voltage at the output of the chokes at different frequencies of the carrier signal, it was noted that at a higher frequency, the ripple of the output voltage decreases. Throttles do not eliminate harmonics, but only reduce their amplitude. Based on the results, it was concluded that the algorithm with a triangular carrier signal and the maximum frequency provides the best harmonic composition of the output voltage of the frequency converter.

Computer-measuring system of the induction motor's dynamical torque-speed characteristics In the article an efficient method of determining the dynamic torque-speed characteristic of induction motors and the computer-measuring system for its realization is considered. In this method, the additional flywheel is used, the dynamic measurements of the angular speed as a function of time are taken at the start, after the end of the transition process, and at during the self-braking mode of the induction motor. For approximating the data that are obtained as a result of the measurements, the moving average algorithm is used. Also, with the help of this system, the inertia moment, angular speed dependence on time, electromagnetic dynamic moment dependence on time, electromagnetic dynamic power dependence on time, mechanical dynamic power dependence on time, and dynamic loss in rotor winds dependence on time are measured. In the article, the results of experimental measurements of the induction motor characteristics using a proposed computermeasuring system are given. The proposed system is experimental; in the future, it can be used to test induction motors during their production processes.
