Question

What is the name of AC to AC converter?

Answer 1

An AC to AC converter is called a AC-AC converter or AC regulator. More specifically, it can be categorized based on the type of conversion or regulation it performs:

1. Cycloconverter: Converts an input AC voltage at one frequency to an output AC voltage at a different frequency. It can directly change both the amplitude and frequency of the input AC signal.
   

1. AC Voltage Regulator: This adjusts the amplitude of the AC voltage, often by controlling the duty cycle of the signal. It is commonly used for controlling the voltage supplied to devices like fans, lights, and motors.
   

1. Phase-Controlled Rectifiers: These are used to convert AC to DC and then use another converter to turn it back into AC, often used in motor speed control applications.
   

If you're dealing with AC voltage regulation and frequency changes, cycloconverters and AC voltage regulators are typically the main types of AC-to-AC converters.
