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).
