Disregarding compensator transformer TB1(main transformer) impedance voltage drop the time have:
Uout=Uin+△U
In formula: Uin-voltage stabilizer input phase voltage, Uout-voltage stabilizer output phase voltage, △ U-compensator transformer TB1(main transformer) secondary compensation voltage.
The bucking voltage regulating circuit 2 of this three-phase controllable silicon AC voltage regulator is by adjustable transformer 21(TB2, the secondary change), silicon controlled module and driving circuit form.Wherein, adjustable transformer 21(TB2, secondary change) into many taps autotransformer ，Mei road tap, by 1 group of several transwitch, controlled.Transwitch S1～S5 is bucking voltage size change-over switch, transwitch S0, S7～S10 be zero-compensation, just compensate, negative compensation change-over switch, change the conducting state of each transwitch, can change compensator transformer 1(TB1, main transformer) voltage swing on primary coil and direction, thus TB1 level can produce all variable bucking voltage △ U of size and Orientation.
When input voltage Uin changes or cause that because of load variations output voltage U out changes, 3 pairs of transwitchs of intelligent control circuit (S0～S10) are adjusted switching, thereby realize automatically keeping the purpose of output voltage stabilization.
Be only preferred embodiment of the present utility model in sum, not be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modify, all should be technology category of the present utility model.
