Constant Voltage Transformers(CVT)
Constant Voltage Transformers(CVT)
The constant voltage transfer generates constant output voltage for a specific input voltage and specific load range.
The CVT is non – linear transformer and works on Ferro – resonance principle. The transformer operates in the magnetic saturation region as per ferro – resonance principle therefore if there is any change in the input voltage, magnetic flux does not change and output voltage remains constant. Simply, the ferro – resonance works as a flux limiter not voltage regulator.
