Controllers for Voltage Stabilisers
A QuadCore controller drives four small transformers.
Transformers, selected in groups of four, produce correction voltage in 32 linear steps.
A controller computes the transformer combination for the right correction voltage.
When the input changes, new correction voltages are applied.
Transformers are selected free of stress at zero crossing moments in the sine wave.
Output voltages are precise, steady, stable and pure sine wave.
Overload capacity allows motors to start and to reverse.
There is no upper power limit for this technology.
No high frequency switching. Filters and shielding are not required.
No contacts, no moving parts. Switching is performed by reliable SCRs.
No maintenance is ever required; life expectancy is not limited.
