Automatic Voltage Regulators Compensate For The Voltage Amplitude And Polarity Of Transformers In Series Main Circuits.

Unit voltage regulator 10kva samples the main circuit voltage in real time and inputs the deviation signal to the control unit, thereby superimposing or canceling the voltage applied to the secondary winding of the compensation transformer with the main circuit voltage according to a set relationship (same polarity or opposite polarity). This process brings the voltage at the load end of the main circuit closer to the desired value while maintaining voltage waveform stability.

During operation, unit voltage stabilizer 380v collects the difference between the main circuit voltage and the set reference value, and then drives the power devices via the controller to change the series voltage of the compensation transformer, thereby altering its output polarity and amplitude. Through this series structure, the compensation transformer can either output a voltage in phase with the main voltage or output a reverse voltage to reduce the main voltage deviation.
