(A), automatic compensating power voltage regulator 

 The basic structure: the motor to drive the carbon brushes in the self-coupling transformer winding inter-turn sliding directly regulate the output voltage or adjust the output voltage through compensation transformer. 
 Advantages: with a load capacity, high efficiency, small waveform distortion, and power of their own anti-jamming ability. 
 The field of application: industry, agriculture, transportation, telecommunications, military, railway, research and culture of large mechanical and electrical equipment, metal processing equipment, production lines, built rental construction equipment, elevators, medical equipment, embroidery, textile equipment, air conditioning, radio and television and home electricity along, led lighting, etc. need the place of the regulator. 

 (B), purified AC voltage regulator 

 The basic structure: a method of combining sine wave energy distribution and the filter, to regulate the output voltage by adjusting the primary circuit of SCR conduction angle. 
 Advantages: high regulation accuracy of ≤ ± 1%, the fast response time ≤ 40ms, Rush pulse filtering effect. 
 Applications: precision electronic equipment, medical equipment, computer rooms, laboratories, product aging test. 

 (C), non-contact AC voltage stabilizer 

 Basic structure: the voltage or current zero crossing switching one or more group SCR leaving make compensation to one or more transformers in the transformer group compensation winding boost, buck, the primary short-circuit, or switch from the lotus transformer tap to adjust the output voltage. 
 Advantages: with a load capacity, high efficiency, small waveform distortion, fast response time and low noise. 
 Application: all the needs of the place of the regulator. 

 (D), the parameter regulator 
 The basic structure: the saturation characteristics of the core material to sudden now output voltage is basically stable.
