- found: Wikipedia, viewed March 6, 2019(Frequency changer; also, frequency converter; an electronic or electromechanical device that converts alternating current (AC) of one frequency to alternating current of another frequency. The device may also change the voltage, but if it does, that is incidental to its principal purpose, since voltage conversion of alternating current is much easier to achieve than frequency conversion. Traditionally, these devices were electromechanical machines called a motor-generator set. Also devices with mercury arc rectifiers or vacuum tubes were in use. With the advent of solid state electronics, it has become possible to build completely electronic frequency changers. )
- found: Georator Corp. web site, viewed June 25, 2019(WHAT IS A FREQUENCY CONVERTER?A frequency converter, also known as a frequency changer, is a device that takes incoming power, normally 50 or 60 Hz and converts it to 400 Hz output power. Different types of power frequency converters exist, specifically, there are both rotary frequency converters and solid state frequency converters. Rotary frequency converters use electrical energy to drive a motor. Solid state frequency converters take incoming alternating current (AC) and converts it to direct current (DC).)
