Ⅰ. Introducción

Voltage regulators are essential in modern electrical systems to maintain stable voltage and protect equipment. This article compares carbon brush and contactless voltage regulators across multiple dimensions, including their working principles, performance, applications, and more. By understanding the advantages and limitations of each type, readers can make informed decisions when selecting voltage regulators for their specific needs. Special attention is given to BKPOWER’s BK-AVR contactless voltage regulator.

Ⅱ. Working Principle of Carbon Brush Voltage Regulator

Carbon brush voltage regulators operate based on the motor-driven rotation of carbon brushes. The motor adjusts the position of the carbon brushes according to voltage fluctuations, altering the transformer’s voltage ratio to achieve voltage regulation. The structure is relatively simple, but it suffers from significant issues such as carbon brush wear and sparking at the contact points.

  • Carbon Brush Wear: Carbon brushes gradually wear down during use, requiring regular replacement.
  • Sparking: Sparks may be generated when carbon brushes contact the slip ring, posing safety hazards and potentially interfering with other electrical equipment.

Ⅲ. Working Principle of Contactless Voltage Regulator

Contactless voltage regulators employ semiconductor devices like thyristors for voltage regulation. By controlling the conduction angle of thyristors, the input voltage can be adjusted to achieve the desired output voltage. This design eliminates mechanical contacts, avoiding problems associated with carbon brush wear and sparking.

  • Semiconductor Devices: Use thyristors to achieve voltage regulation.
  • No Mechanical Contacts: Avoid issues related to carbon brush wear and sparking.
