We the
team of “ASHOK ELECTRICAL” are obliged to introduce to you yet another finest
product, 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 ferro resonant 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.
