Product & Technology News
- The ferro resonant transformers, also known as constant voltage transformers (CVTs) or ferros, provide good surge suppressions through high isolation and inherent short-circuit protection.
- The phenomenon which makes the CVT special is ferro resonance; this is achieved by resonating of the output secondary coil with selected high stability capacitors.
- This resonant circuit is so dimensioned that the secondary part of the transformer core is separated during each half cycle, providing constant output voltage even for large variations in the input voltages.
- By design Purevolt's CVT has sinusoidal waveform; all problems related to variation/fluctuations in voltage are affectively handled because of this principle and a constant voltage output of +- 1 per cent is given by the CVT.
- 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.
