Embodiment Construction

[0037] The present invention will be further described below in conjunction with accompanying drawing.

[0038] figure 1 It is a block diagram of an AC voltage stabilizer system composed of an AC voltage stabilization controller and a compensating main circuit. The AC voltage stabilization controller includes a sampling comparison unit, a delay protection unit, an interlock control unit, an error detection control unit, a trigger unit, and a sampling unit. The comparison unit performs voltage sampling on the AC power supply voltage, and outputs the coded value of the voltage level P2; the delay protection unit inputs the coded value of the voltage level P2, outputs the coded value of the delayed voltage level P3 and the non-triggering zone control signal P4; the interlock control unit inputs The delayed voltage level code value P3 and the non-trigger zone control signal P4 output the trigger control signal P5; the trigger unit sends the trigger signal P6 according to the input...

Abstract

The invention relates to an alternating current voltage stabilizing controller which comprises a sampling comparison unit, a delay protection unit, an interlocking control unit, an error detection control unit and a trigger unit, and aims at controlling a compensate-type main circuit comprising a compensation transformer set and a thyristor bridge. The sampling comparison unit samples an input voltage and outputs a voltage level code value, the delay protection unit outputs a delayed voltage level code value and a non-trigger area control signal to the interlocking control unit, and the interlocking control unit outputs a trigger control signal to perform a compensation control. When the alternating current voltage stabilizing controller realizes an interlocking control, the error detection control unit also judges and sends out a corresponding protection control signal under conditions that the sampling comparison unit fails and outputs an invalid code value and the interlocking control unit has a logic error and the like, so that protection of an abnormal working process is effectively improved, and a working process of alternating current voltage stabilization is more stable andreliable.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to an AC voltage stabilizing controller. Background technique [0002] The existing compensating single-phase and three-phase AC voltage stabilizers have the advantages of wide range of voltage regulation, almost no distortion of the waveform, high overall efficiency and strong load adaptability. The principle is to automatically control the switching of different winding coils of the primary winding on the compensation transformer according to the level of the input voltage, using the ratio relationship between the primary side working winding and the secondary winding, or by adjusting the voltage applied to the primary winding , providing bidirectional and multi-level voltage compensation, so as to achieve the purpose of voltage regulation and stabilization. [0003] The disadvantage of the existing compensated AC voltage stabilizer is that when the motor is used to contro...
