Converter

The process of changing AC to DC. This is
accomplished through the use of a diode
rectifier or thyristor rectifier circuit. The term
“converter” may also refer to the process of
changing AC to DC to AC (e.g. adjustable
frequency drive). A “frequency converter”, such
as that found in an adjustable frequency drive,
consists of a Rectifier, a DC Intermediate
Circuit, an Inverter and a Control Unit
