FAQ
What is a Static Frequency Converter?
A static frequency converter (SFC) is a type of power electronic device used to convert alternating current (AC) of one frequency to alternating current of another frequency. Its main function is to change the frequency of the power supply to suit the needs of different equipment, especially in applications that require a stable, frequency-specific power supply. The main purpose of a static inverter is to enable equipment requiring power at different frequencies to operate seamlessly with the available power supply. In many parts of the world, the standard frequency for AC power distribution is 50 Hz or 60 Hz, depending on the region. However, in some cases, equipment or systems designed for one frequency need to be used in areas with different frequencies. This is where static inverters come into play.
A static inverter is an important power electronic device that is widely used in aviation, marine, power systems and industrial manufacturing. Its main function is to provide a stable, frequency-specific power supply through frequency conversion to meet the special needs of various equipment and systems. Due to its high efficiency, high stability and low maintenance cost, static inverter has an important position in modern industrial and technical applications.
