Converters & Their types
Converters:
Converters are used to convert AC power to DC power. Virtually all electronic devices require converters. They are also used to detect amplitude modulated radio signals. They are also used to supply polarized voltage for welding. Converters can be used for DC to DC conversion. Here, the inverter converts DC to AC, then a transformer is used to convert it back into DC.
The basic difference between various types of converters is that they vary in their nature and the devices they support.
Analog-to-digital converter (ADC)
The analog-to-digital converter is a device that converts the input analog voltage to a digital number proportional to the magnitude of the voltage or current. Some non-electronic or partially electronic devices, like rotary encoders, can be considered as ADCs.
Digital-to-analog converter (DAC)
Digital-to-analog converter is a device that converts a digital code to an analog signal. DAC is found in CD players, digital music players, and PC sound cards.
Digital-to-digital converter (DDC)
Digital-to-digital converter is a device that converts one type of digital data to another type of digital data.
