“…If the voltage drop lasts longer than 2 to 3 cycles, sensitive loads may gets damaged during this time. On the other hand, the voltage swell is caused by turning on the capacitor, relieving or shutting off heavy loads [1]. Both voltage drop and swelling cause interference in sensitive components such as computers, communication services, medical systems and prolonged power shutdowns [2].…”

The paper presents a compact AC-AC single phase voltage regulator based on Impedance network. The proposed topology has ability to perform buck and boost operation in a single stage .The circuit is simple, highly efficient and more importantly reduced manufacturing cost due to its minimal number of active and passive components. The Impedance network has dual function of boosting and filtering. The proposed topology employs two bidirectional switches operating at high frequency PWM pulses. The high frequency switching reduces the size of the Impedance network. The gain of the system is controlled by controlling the duty cycle of the bidirectional switches. The operating mechanism of the proposed topology along with simulation and experimental results are presented.
