Frequency Converter, aka AC power supply / frequency changer, is electric supply conversion device. It converts the alternating current in the electric supply through AC-DC-AC, and outputs pure sine wave. The frequency converter changes a fixed-frequency (50 Hz, 60 Hz), fixed-voltage (110V, 120V, 220V, 230V, 240V, 380V, 400V, 440V, 480V etc.) sine wave power to a variable-frequency (50Hz, 60Hz or 400Hz adjustable), variable-voltage (1-phase 0-300v adjustable, 3-phase 0-520v adjustable) output used for international appliances compatible, make power source with no difference among countries.
