The buck-boost inverter provides boosting and inversion function in a single power processing stage based on the front end buck-boost converter characteristics. The static stabilizer offers a reasonable on slow servo controlled stabilizers well as other static tap changing stabilizer. 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 buck-boost transformer. The voltage regulation of this topology is achieved electronically with the step changes in voltage. This task is accomplished through a feedback and control system implemented. The system used IGBTs as power switches. Direct AC-AC converter circuit improves the overall system response and fast voltage correction. Number of storage capacitor increase life of the system. 20 KHz PWM control operation using Microcontroller Atmega16 to achieve time of 1 to 1.5 cycles. Simulation results assure the proposed novel concept of single phase buck-boost inverter.
