“…The main disadvantage of such devices can be considered the presence of odd harmonics in the output signal, which significantly worsens the values of the harmonic coefficient and affects the increased consumption of reactive power at the input [5,6]. This disadvantage can be eliminated, the first method is algorithmic [7,8]. It is enough to monitor the voltage to achieve the required engine speed, since voltage and speed are proportionally related [9].…”

The formation of the required AC voltage level is currently one of the most important problems. An unstable voltage level can lead to the failure of domestic and industrial equipment, also to the appearance of a lighting equipment flicker effect, which can adversely affect the operating mode. In this regard, the development of AC voltage regulators that perform the function of stabilizers has become relevant. In turn, new topologies should be energy efficient and reliable, this can be achieved by reducing the number of semiconductor elements, which in turn will reduce losses and increase efficiency. In addition to voltage stabilization, AC voltage regulators have found application as soft-start devices for asynchronous motors, and have become competitors to frequency converters. The power level can vary from units to tens of kilowatts where such devices can be used. This paper provides a review of AC voltage regulators, which can be used both as soft starters and AC voltage stabilizers. The analysis of the circuits was carried out and the efficiency was evaluated through their total harmonic distortions (THD), power factor and efficiency coefficient. Experiments were also performed for a number of circuits, where their operating modes were evaluated. Eventually, all circuits were divided into full number of switches with two or more AC switches per phase, with a reduced number of switches, where one AC switch per phase and with low number of switches – with one complementary pair of AC switches for all three phases.

Induction motors are used in industry in variety of achieved with an AC voltage controller using thyristors. By applications such as blowers, fans, compressors, pumps, mixers, using different time functions for the firing angles of thyristors, crushers and grinders etc. Soft starters, involving voltage ossible to controllers, are used for starting and speed adjustment of .tai t spee in ducton toritha chsen induction motors. This paper presents a neural network based constant torque. The initial value of the firig angle ensures soft starter which controls the speed by the adjustment of firing that the first current peak does not exceed the rated value. The angles of thyristors. The suggested technique eliminates the final value of the firing angle, from the first function, will set starting torque pulsations by triggering the back to back the starting torque on the desired value. By keeping this firing connected thyristors. The control strategy is implemented using angle constant for a while, the motor accelerates with the microcontrollers and neural networks and performance analysis hosen constant tor a 1 teh of the system is carried out with the help of hybrid model of chosen constanttorque [6-10]. induction motor. The results obtained are satisfactory and
