A frequency converter is an electronic device used to control the rotational speed and torque of an electric motor. The motor, in turn, drives a load (e.g. a pump). A frequency converter converts the mains AC voltage into DC voltage via a rectifier and is stabilised by the DC link capacitor bank. The inverter finally converts the DC voltage back into AC with variable frequency. Frequency inverters for primary water and waste water treatment applications are equipped with various customised functions for controlling single and multi-pump systems.
