The paper presents the method of synthesizing the algorithm for controlling semiconductor locks of three-phase inverter circuits according to the asymmetric 180-degree switching law to control three-phase asynchronous motors, and simultaneously evaluating, comparing oscillation speed and motor torque of motor when increasing pulse width modulation frequency. The results are surveyed and evaluated by simulation models on Matlab-Simulink software. The model allows us to evaluate the quality of speed and torque control of three-phase asynchronous motors when using the asymmetric 180-degree switching algorithm. At the same time, this switching algorithm also eliminates co-conductive current in the columns of the inverter circuits thanks to using the brake mode by closing the semiconductor locks simultaneously.
