Static Voltage Stabilizer or Static voltage regulator is same as servo voltage stabilizer but without any moving part. In Servo Stabilizer correction in output voltage achieve with help of moving tap by servo motor hence correction in voltage takes time. But in Static voltage regulator there is no moving part. Correction in voltage is achieves purely with help of electronic circuits hence it call as static. Static Voltage regulators are basically SMPS based which uses IGBT. Static Voltage stabilizer is new generation of voltage stabilizer based on PWM (Pulse Width Modulation technic). Advantage of static voltage regulator other fast regulation is it achieves regulation without distortion in output waveform. As mentioned before Static voltage stabilizer uses IGBT as power switches. In normal PWM method voltage regulation done by converting input DC voltage to inverter. Input DC voltage achieved by converting AC into DC which mean with help of double conversion. But in case of static voltage regulator there is no need for double conversion where PWM in done directly in AC-to-AC switching and that of without harmonic distortion. Since circuit is fully electronic (no moving partes) or static there will not be any wear and tear of part as in case of servo stabilizer. Voltage correction speed of static voltage regulators can be upto 500 times faster than servo stabilizer. All Capacities of Static stabilizer are same operating principle and in different rating of Static voltage regulator different is only PCB board. It is compact in size and much lighter in weight that servo voltage stabilizer.
