Thyristors Balancing Voltage Regulator with Boost Voltage

This paper examines the problems of improving the power supply quality in four-wire distribution networks of 0.4 kV. The reasons leading to the quality deterioration of the electricity supplied to the consumer are considered. −The operation of known voltage regulators providing stabilization and balancing load voltage is analyzed, their advantages and disadvantages are shown. A new approach to the development of regulator for balancing power supply currents and voltages of the loads based on boost voltage is proposed. The mathematical analysis of electromagnetic processes of proposed devices illustrating efficiency of their work is shown. As an example, the effectiveness of the device installed in a network with an asymmetrical three-phase load is demonstrated.
