Why is regulator control considered superior to thyristor-based control in rectifiers?

  • A highly effective regulator is considered the best choice for plating, and the technology has been widely adopted in Germany and Europe for its numerous advantages.
  • Many rectifier manufacturers have shifted to using thyristors, largely due to their inability to access the advanced rolling carbon roller regulator technology.
  • As a result, thyristor-controlled rectifiers tend to have a lower loss rate than regulators, according to these manufacturers. They often compare thyristors with sliding carbon-type regulators, but in our case, this claim does not hold true. In order to regulate the carbon content, we use a vertical coil-type rolling regulator. The copper section is three times larger, which reduces the losses to about one-sixth, or 20%, of the usual amount.
  • With our regulator, the roller moves on both sides of the coil, giving the output of either 440 V or 254 V. A ‘Q’ connection is used on our rectifiers, where the regulator current is only half that of the line current.This reduces energy losses and significantly extends the equipment’s lifespan.

Starting Circuitry: Power rectifiers are designed for 3-phase, 50 Hz operation. A standard AC input supply in India can support voltages between 380 and 440 volts, but custom adjustments can be made to accommodate 60 Hz AC or other voltage specifications. When performing maintenance or in the event of a fault, it is recommended to connect the rectifier input through an appropriate protective device to ensure both personnel and system safety.

DC Output Control:Making changes to the input voltage which is applied to the primary winding of the main transformer adjusts the voltage, current, or operating range of the transformer. The DC output voltage can be smoothly varied from 0 to 100% using an on-load, roller-type voltage regulator.

Advantages of Roller Type Regulator:

  • There is no waveform distortion at any load. Electrical waves have the same behavior as moving wheels where their diameters decrease proportionally with the rated voltage, which means that the magnitude of the waves decreases.
  • There is an increase in power factor of over 98.
  • The cost of spares is very negligible
  • There are 3 times as many copper sections for particular currents as conventional makes
  • The carbon roller rolls on a coil and lasts more than 20 years without requiring maintenance
  • Over all losses are less

Advantages of Conventional Make :

  • In thyristor-controlled systems, waveform distortion occurs, resembling a scenario where the wheel is cut by 50% before being set in motion.
  • The power factor typically ranges between 0.5 and 0.75.
  • The system is highly specialized, requiring the expertise of specially trained electronic engineers for proper repair and maintenance.
  • The cost of replacement is very high
  • In conventional designs, the copper section used for a specific current is reduced to one-third of the standard requirement.
  • Considering the fact that carbon brushes slide on coils, their lifespan is reduced and they break easily
  • Over all losses are less
