Constant Voltage Transformer And Ultra-isolation Transformer

Constant Voltage Transformer(CVT):-
A Constant Voltage Transformer (CVT) is a non-linear transformer also known as a Ferro-Resonant Transformer (Ferro).

Ferro-resonance is the regulated output provided by a CVT through an electromagnetic phenomenon.

A CVT is basically a 1:1 transformer that is driven high on the saturation curve, thereby providing an output voltage that is not significantly affected by changes in input voltage. This characteristic is the basis for the application of Ferro-Resonant Transformers as power conditioners.

Ultra-Isolation Transformer:-
An ultra-isolation transformer is a transformer used to transfer power from an alternating current (AC) source to some device or equipment while completely isolating the connected device from the source, usually for safety reasons.

An isolation transformer is a transformer, usually with symmetrical windings, used to decouple two circuits. An isolation transformer allows an alternating current (AC) signal or power to be taken from one device and introduced into another device without electrically connecting the two circuits. Isolation transformers block direct current (DC) signals from being transferred from one circuit to another, but allow AC signals to pass through. They can also block interference caused by ground loops. Isolation transformers with electrostatic shielding are used as power supplies for sensitive equipment such as computers, laboratory instruments, CNC machine tools, and medical equipment.

The isolation transformer uses a novel multi-shielding technology, which greatly reduces the capacitance between windings and improves DC isolation.
