Регулируемый источник питания для технологических процессов, использующих электрическую дугу, содержит преобразователь переменного тока в постоянный, имеющий согласующий трансформатор и выпрямитель, который выполнен на вентилях в виде мостовой схемы и связан с согласующим трансформатором, в диагональ постоянного тока которого, являющийся выходом выпрямителя, включены электроды, между которыми образуется электрическая дуга, и схему регулирования напряжения на электродах, имеющую узел сравнения действительного выпрямленного напряжения с заданной величиной напряжения и устройство регулирования положения электрода, вход которого подсоединен к узлу сравнения и которое изменяет положение электродов, один относительно другого. В источнике использован однофазный преобразователь переменного тока в постоянный, имеющий последовательно соединенные между собой две фазосдвигающих цепи, которые взаимосвязаны с согласующим трансформатором, первая из которых содержит дроссель, а вторая - конденсатор, каждая подсоединена к соответствующему входу выпрямителя, дополнительные вентили, имеющие общую точку, связанную с общей точкой фазосдвигающих цепей и подсоединенные к выходу выпрямителя в одинаковой полярности с вентилями выпрямителя, подсоединенными к электродам.Adjustable power supply for technological processes using an electric arc contains an AC-DC converter with a matching transformer and a rectifier, which is made on the valves in the form of a bridge circuit and is connected to a matching transformer whose electrodes are included in the DC diagonal, which is the rectifier output. between which an electric arc is formed, and a voltage regulation circuit on the electrodes, having a reference point for the actual rectified voltage Nia a predetermined voltage value and the electrode position adjusting device, whose input is connected to the comparison node and which changes the position of the electrodes relative to one another. The source used a single-phase AC-to-DC converter that has two phase-shifting circuits connected in series, which are interconnected with a matching transformer, the first of which contains a choke and the second is a capacitor, each connected to the corresponding rectifier input, additional gates having a common point, connected to the common point of the phase-shifting circuits and connected to the output of the rectifier in the same polarity with the rectifier valves connected to the electrodes.
