The static stabilizer offers a reasonable improvement on slow servo controlled stabilizer as well as other static tap changing stabilizers. This technology does not cause di/dt problems as it does not switch the power path. The basic topology is with buck-boost transformer with high primary to secondary ratio for voltage correction of ± 25%. The control voltage is imposed on the primary of this buck-boost transformer. The voltage regulation with help of buck and boost topology is achieved electronically without the step changes in voltage that occur when the system regulates. This task is accomplished through a feedback and a control system implemented by using a microcontroller.
The significant voltage fluctuations that occur on the electrical network simulates the premature ageing of the critical machines and even damages them in most cases. The solution to this type of problem is the use of voltage stabilizers which guarantee that the connected loads will always operate within safe limits at a better efficiency thereby avoiding energy loss.
Static Stabilizer is compatible with all loads as it does not switch any components in the power path, ultra low impedance assures stability even with the most demanding loads. The automatic bypass assures that connected equipment will not shut down, even if the static regulation engine fails.
The higher frequency insulated gate bi-polar transistor (IGBT) driven convertor takes the incoming ac power, measures against the nominal voltage and adds or subtracts voltage, 20,000 times per second, to achieve precisely regulated 230 vac output. The automatic bypass will be activated when there is a fault condition. green LCD are used to indicate Normal (regulating mode) operation.
