As mentioned in Gechy Electric Co.,Ltd Product page, static voltage regulator does not includes any moving parts unlike servo voltage regulator. It achieves voltage regulation with help of static electronic circuits only. In this discussion we will understand working of Static voltage stabilizer. For better understanding of working of these type of voltage regulator Gechy Electric Co.,Ltd tell you need to understand it's major components.

Major Components of Static voltage Stabilizer.

Please refer diagram below. Lets understand major components of Static voltage regulator.

1. Buck Boost Transformer: Secondary of Buck and boost transformer is connected input and output terminal of voltage stabilizer. Neutral between input and output of static voltage stabilizer is common hence voltage induced across secondary of buck boost transformer can add or subtract with input voltage. Primary of buck boost transformer is connected to IGBT power stage.

2. IGBT Power Stage: It consists of IGBT bridge which connected to DSP controller. IGBT power stage responsible to generate appropriate amount of voltage with help of PWM method. Output voltage of IGBT bridge is applied across primary of buck boost transformer. IGBT bridge can generate voltages at its output (which applied across primary of buck boos transformer) which can be in phase or 180 degree out of phase with input line voltages so that voltage induced across secondary of buck boost transformer can be added to or subtracted from input line voltages.

3. DSP based Control board: Control board continuously senses valued of  input voltage, output voltage, load current and IGBT current with help of Current transformer and voltage transformer connected to it. It processed information and gives signal to IGBT power stage to generated voltage with help of PWM method.
