Frequency Converter FAQ

  • What is a Frequency Converter?

    A Frequency Converter is a device that converts the AC of one frequency to another frequency. In addition, usually the Frequency Converter will also convert the voltage, providing a variable output.

    These systems can also be referred to as Frequency Changers or AC to AC Frequency converters.

  • What is difference between SFC and RFC?
    SFC Static Frequency Converter – This the modern method of frequency conversion with no moving parts, utilising electronic solid state Pulse Width Modulation units.

    RFC Rotary Frequency Converter – This was the chosen method prior to SFC systems, using electro mechinical motor to generate/adjust the frequency of the waveform.
