Frequency converters are designed to supply the power receipts with other parameters of voltage and frequency parameters than the main power grid. They are used in the power infrastructure of ports, airports, military installations and offshore. There is also the possibility of two-way flow of energy and control the flow of power.
They are performed in modern IGBT technology. They are characterized by high stability of output voltage, low noise, resistance to overload. Among their other features are: resistance to external interference and change the parameters power protection against short circuits, too low and too high voltage isolation of output circuit from the power circuit, automatic operation, full maintenance-free, high efficiency and power factor close to 1.
