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 system uses IGBTs as power switches. Direct AC-AC converter circuit improve the overall system response and fast voltage correction. No storage capacitor increase life of the system. 20Khz PWM control operation using high end dsPIC controller to achieve correction time of 1 to 1.5 cycle. Excellent performance in voltage sensitive application.
