Abstract

The invention relates to an AC voltage-stabilizing energy-saving device of a compensation transformer, which comprises a tapped transformer and the compensation transformer, wherein a secondary coil of the compensation transformer is connected between a power supply and a load in series; the tapped transformer comprises 2K taps, wherein K taps are respectively connected with a primary coil of the compensation transformer in an inputting way by a second bidirectional controllable silicon, and the other K taps are respectively connected with the primary coil of the compensation transformer in an outputting way by a first bidirectional controllable silicon; the output of the first bidirectional controllable silicon is connected with the output of the primary coil of the compensation transformer by a first T descending controllable silicon; the output of the first bidirectional controllable silicon is connected with the input of the primary coil of the compensation transformer by a first T rising controllable silicon; the output of the second bidirectional controllable silicon is connected with the input of the primary coil of the compensation transformer by a second T descending controllable silicon; and the output of the second bidirectional controllable silicon is connected with the output of the primary coil of the compensation transformer by a second T rising controllable silicon. The AC voltage-stabilizing energy-saving device of the compensation transformer realizes voltage compensation with low cost, wide range and high accuracy.

Description

technical field [0001] The invention relates to the field of circuit technology, in particular to an AC voltage stabilizing energy-saving device for a compensation transformer. Background technique [0002] The compensation transformer type AC voltage stabilizing energy-saving device is to connect a set of transformer coils in series in the main circuit, and the potential generated by the transformer coils is superimposed with the main power supply, thereby changing the output voltage value. Since the transformer coil is not directly used for power supply, but only for compensation (about 20% of the total power supply voltage), the power and volume of the transformer can also be reduced to 20%, which can save a lot of copper wires, iron cores, etc. Material. [0003] see figure 1 , which is a circuit diagram of an existing compensating transformer AC voltage stabilizing energy-saving device. figure 1 The left side of the center is the power input, and the right side is co...
