FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering and electric power industry and can be used in power supply systems of industrial enterprises, for social needs and autonomous power supply systems, for stabilizing and regulating voltage on power lines, controlling bandwidth and regulating active and reactive power. A three-phase booster device with high-frequency galvanic isolation contains an input three-phase rectifier, an output three-phase inverter, output booster transformers, input and output passive filters, differs in that a double active bridge with high-frequency galvanic isolation is installed between the three-phase rectifier and the three-phase inverter allows you to change the level of the rectified voltage, thereby improving the quality of the boost voltage and providing additional reliability due to galvanic isolation.
EFFECT: invention provides the accuracy of work and safety of operation of the booster device while reducing the volume and weight of the device.
