ZSBW work principle 
 Contact series regulator voltage compensation, voltage detection, optical isolators, drive, electronic switch, and digital conversion, microcontroller intelligent control systems, etc. components. 
 The regulator's output voltage and input voltage between the following relationship: 
 UO = Ui ± △ Uc △ Uc = ± △ Uc1 ± △ Uc2 
 Where ± △ Uc1 ± △ Uc2 respectively for T1 and T2 compensation voltage, △ Uc is the total compensation voltage, ± △ Uc1 + ± △ Uc2 - △ Uc1-△ Uc2 constitute the largest positive compensation voltage and the maximum negative compensation voltage When TR4, TR6 conduction, T1 primary short-circuit the secondary induced voltage △ Uc1 = 0, the same TR4, TR5 conduction △ Uc2 = 0 the TR7 conduction (J1, J2, connected), △ Uc = 0. 
 The regulation process is: change the grid line input voltage, the voltage detection unit sampling, the change in voltage analog signal converted to digital signals; by micro-computer, pre-programmed and pre-built data. Directives issued by the MCU intelligent control system conduction to the optical isolation couplers, the contacts of the drive is neither fast electronic switch circuit, and amount of compensation for the accuracy of the output voltage, so that the output voltage adjustment allowable error in the accuracy within in order to achieve the purpose of completion of the automatic voltage regulator.
