Absract <p>Results of the development of and research in a reversing rectifier cell powered by a current loop for high-voltage sources of industrial electron-beam welding installations and power transmission systems are presented. The principles of its operation in direct and reverse modes are studied. Approaches to designing a control system with separate synchronization of two independent linearly varying voltage generators are proposed, the beginning and end of the control pulse being synchronized with the first or second generator, depending on the energy transfer direction. A model has been developed in the MATLAB Simulink environment, which made it possible to refine the structure of the control system and algorithms for controlling the cell in static and dynamic modes. Transient processes during operation without load and abrupt changes in the output voltage setpoint, as well as the operation of the cell under load, are analyzed.</p>
