Podnebennaya S. K. Three-to-one phase converter's control method for powerfactor corrected power supply of resistance welding machine [Електронний ресурс] / S. K. Podnebennaya, V. V. Burlaka, S. V. Gulakov // Науковий вісник Національного гірничого університету. - 2018. - № 4. - С. 106-114. - Режим доступу: http://nbuv.gov.ua/UJRN/Nvngu_2018_4_17 Purpose. The improvement of control method for a three-to-one phase matrix converter of a power supply of a single-phase resistance welding machine. This allows ensuring electromagnetic compatibility of the power supply with the power network, increasing the converter efficiency by reducing the switching frequency of power switches, and reducing power losses therein. Methodology. To study the power characteristics of power supplies for resistance welding machines, methods of mathematical and simulation modeling were used. The synthesis of the control system is based on the obtained regularities, characteristics and generalized requirements applicable to power supplies for resistance welding machines. Findings. The control algorithm for the three-to-one phase matrix converter of the power supply of resistance welding machine is developed. A control system based on this algorithm is synthesized. A mathematical simulation of a power supply with a developed control system is performed. A control method of the direct converter of the resistance welding machine power supply is developed. It ensures electromagnetic compatibility with the supply network and improves the converter efficiency. Originality. A method for controlling the three-to-one phase matrix converter, based on one-cycle control algorithm, is proposed. This method consists of sequential switching of bidirectional converter switches. Their switching on depends on the network voltages according to a given algorithm. The commutation moments are determined by the time when the current integral reaches the value of the reference charge, calculated in accordance with the value of the active resistance simulated by the converter with respect to mains. Practical value. The use of a direct matrix converter for supplying the resistance welding machine, which is controlled by the developed algorithm, makes it possible to ensure electromagnetic compatibility of the power supply with the power network and increase its energy efficiency by reducing the switching frequency of power switches, reducing power losses therein. | ||

Burlaka V. Design of an universal source for semi-automatic AC welding and induction heating [Електронний ресурс] / V. Burlaka, E. Lavrova, S. Podnebennaya, V. Ivanov, S. Burikov // Eastern-european journal of enterprise technologies. - 2021. - № 6(1). - С. 38-46. - Режим доступу: http://nbuv.gov.ua/UJRN/Vejpte_2021_6(1)__7 This paper proposes a circuit solution and a power source control algorithm for semi-automatic AC welding with improved energy and weight-size characteristics. A distinctive feature of the designed source is the absence of an input rectifier: welding is carried out with a high-frequency alternating current. That has made it possible to significantly reduce power losses in the source, as well as provide the possibility of implementing induction heating by connecting an inductor to the source output. Another distinctive feature of the designed source is an increased power factor and a reduced level of higher harmonics of the current consumed. The power factor of the described source reaches 0,94 against 0,5 - 0,7 for sources equipped with a conventional rectifier with capacitive smoothing. The designed source's composition includes a power supply system for the wire feed drive with speed stabilization due to positive feedback on the motor current. That has made it possible to ensure the stable operation of the drive in a wide range of speeds. A model has also been developed of a flux wire welding torch containing a feed drive and a coil with a wire (up to 100 mm in diameter), placed, in order to reduce the size, in the handle of the torch. In addition to the welding function, the source makes it possible to solve the tasks related to induction heating and/or hardening of small parts; to that end, a compact inductor is connected to its output. Tests of the source showed the feasibility of the proposed ideas and circuit solutions. The dimensions of the source are 190 x 107 x 65 mm; weight, 1,4 kg; output current, up to 120 A. The proposed technical solution enables the construction of small-sized, lightweight, universal, easy-to-use power supplies for semi-automatic welding with the option of induction heating. | ||
