Constant Voltage Transformer

In our Ferro Resonant type Constant Voltage Transformers - CVT, the AC mains power the input winding, which is widely separated physically from the isolated output winding. The input winding normally runs at very moderate Flux linkage levels. The output winding exhibits an intrinsic energy characteristic and this energy storage operate in conjunction with mains capacitor to produce self-generated AC flux Field which is indirectly extracted from the Input Winding.

These Constant Voltage transformer or CVT use a tank circuit composed of a high-voltage resonant winding and a capacitor to produce a nearly constant average output with a varying input. The ferroresonant approach is attractive due to its lack of active components, relying on the square loop saturation characteristics of the tank circuit to absorb variations in average input voltage.

The ferro-resonant action is a flux limiter rather than a voltage regulator, but with a fixed supply frequency it can maintain an almost constant average output voltage even as the input voltage varies widely.

All problems related to variation / fluctuation in Voltages are effectively handled because of this principle and a constant voltage output of ± 1% is given.

Purevolt is a leading supplier and exporter of PWM IGBT Static Voltage Stabilizers or regulators. These static stabilizer and regulators are majorly made keeping in view of changing requirements of the industrial machinery and its applications. Some machinery requires very accurate and fast response time which is not possible to achieve from traditional stabilizers or regulators, that whether the static stabilizer comes to the rescue of the industry. The static stabilizer employs IGBT based switching technology with microcontroller based control systems which ensures stable output voltage even in case of large input variations.

  • What are limitations of available voltage regulators? 
  • Since Long, conventional methods like Servo voltage stabilizer and Tap Changer AVR are used In industrial, commercial and residential application. But, these technology has following limitations,

    • Very slow correction speed

    • Slow Correction time

    • Interrupts power path at the time of regulation (tap changing method)

    • Mechanical component limitation or failure

    • Manual Bypass

    • Low reliability

    • Low regulation

  • What are the advantages of Static Voltage Regulator?

    • Compact in the size compare to conventional regulator

    • Very fast correction speed of 20Khz

    • Very fast correction time of 20-30ms as compare to conventional regulator (200 – 5000ms)

    • Excellent voltage regulation of +/- 1%

    • Auto bypass

    • No moving parts so no wear and tear and high reliability No maintenance

    • Silent operation

    • Excellent load protection capabilities to ensure load life

 

Rating Available for Static Voltage Stabilizers & Regulators :

1 KVA to 20 KVA - 1 Phase
