Simulation and study of the operating modes of a semiconductor converter with intermediate link for energy storage in the power supply system of a magnetodynamic installation (MDI) are carried out. The process of controlled periodic replenishment with energy of an oscillatory circuit with a load is studied in detail. The efficiency of the semiconductor converter as a regulator of the magnitude and phase of the voltage on the electromagnet of MDI is shown, which provides high-quality regulation of the electromagnetic pressure acting on the molten metal in the MDI. Reference 6, figures 4.
Key words: semiconductor converter, intermediate link for energy storage, storage and compensating capacitor, magnetodynamic installation, electromagnetic pressure.
