An engineer inspects a large synchronous converter in a power plant control room.

Definition

Noun: 1. A type of electrical converter: A synchronous converter is a specific kind of electrical machine. Its primary function is to change alternating current (AC) into direct current (DC), or to perform the reverse operation, converting DC into AC.

Usage Notes

• A synchronous converter is a rotating machine, meaning it has moving parts, unlike modern static semiconductor-based converters.
• It combines the functions of a synchronous motor and a DC generator (or vice-versa) within a single unit.
• This term is largely historical, as these machines have been mostly replaced by more efficient and maintenance-free solid-state converters (like rectifiers and inverters). You will encounter it in technical texts discussing older power systems.

Examples

• Noun:
  • The power substation used a large synchronous converter to provide DC for the city's tram system.
  • Before the invention of modern rectifiers, synchronous converters were essential for industrial processes requiring direct current.

Advanced Usage

• Rotary Converter: This is a common synonym for a synchronous converter, emphasizing its rotating nature.
• In early 20th-century electrical engineering, a was a key component for linking AC distribution networks with DC loads like elevators and industrial motors.

Variants and Related Words

• Converter (n): The general category of devices for converting electrical energy from one form to another.
• Rotary Converter (n): A direct synonym for synchronous converter.
• Synchronous Motor (n): An AC motor that runs at a constant speed synchronized with the frequency of the supply current; it is a key component a synchronous converter.
• Dynamotor (n): A similar type of rotating electrical machine that converts voltage levels of DC power.

Synonyms

• Rotary converter

Antonyms / Contrasting Terms

• Static Converter (n): A converter with no moving parts, such as a semiconductor-based rectifier or inverter.
• Rectifier (n): A device (now typically static) that converts AC to DC only.
• Inverter (n): A device (now typically static) that converts DC to AC only.
