Converter

A circuit that converts AC to DC or from DC to AC or acts as AC frequency changer. Modern electric drive systems, in which speed control of the electric motor is required, use power supply converters. These converters adapt the voltage and frequency of the power supply to the electric motor as required for the desired motor speed. The basic components of the converters are diodes, transistors and thyristors.
