[one] technical field the utility model is related to a kind of contactless alternating current voltage stabilizer, especially AC chopping pressure regulation AC voltage regulator.
[two] at present, the AC voltage regulator of known AC chopping pressure regulation has background technology:1 alternating-current chopper circuit and 4 The chopped mode AC voltage regulator of individual bidirectional electronic switch paraphase.It is authorized notification number CN203104296.C and announces same application human hair The continuous stepless contactless alternating current voltage stabilizer of bright chopper control, it only with 1 centre have the auto-transformer of 2 taps, 1 piece Double IGBT modules, 1 piece of double SCR modules and its trigger control circuit just realize the contactless AC voltage-stabilizing of single-phase continuous stepless, for drop The number of turn of low auto-transformer reduces cost, and same applicant obtains again to be authorized notification number CN203840206.U another is special Profit --- single-phase and three-phase AC voltage stabilizer.The problem of it is present is the design of auto-transformer ceiling voltage, it is necessary to by input Voltage ceiling voltage is designed, and therefore, auto-transformer cost is still too high.
[three] content of the invention the purpose of this utility model is the voltage on 2 terminations of further reduction auto-transformer, drop Low umber of turn and cost, to achieve these goals, the utility model provide a kind of single-phase contactless high accuracy of continuous stepless AC voltage regulator, it is made up of alternating-current chopper circuit and step-up auto-transformer, and alternating-current chopper circuit is by inductance, electric capacity, master control Bidirectional electronic switch, afterflow bidirectional electronic switch and its control circuit composition, it is characterised in that:Step-up auto-transformer is connected to Alternating-current chopper circuit exports two ends, and master control bidirectional electronic switch and afterflow bidirectional electronic switch are all by 4 diodes and 1 three Pole pipe is constituted, and alternating-current chopper circuit is controlled using complementary, and master control bidirectional electronic switch, inductance, electric capacity order are connected to alternating current Pressure input two ends, afterflow bidirectional electronic switch and inductance, capacitance series branch circuit parallel connection, step-up auto-transformer input two ends and electricity Hold parallel connection, two terminations of step-up auto-transformer are two output ends of AC voltage regulator.
The above-mentioned 3 single-phase contactless high accuracy A. C. voltage stabilizers of continuous stepless are connected into star just constitute 1 three and be connected Continuous stepless and contactless high accuracy A. C. voltage stabilizer, it just has 1 exchange input and AC voltage-stabilizing output public zero curve (N), 3 three Cross streams input (A1, B1, C1) and 3 three-phase alternating current output end of pressure-stabilizing (A2, B2, C2), three-phase 380V friendships can be exported simultaneously Stream burning voltage and three single-phase 220V for having public zero curve N exchange burning voltage, with the regulation two-way full control electronic cutting of 3 master controls The make-to-break ratio regulation offset voltage size in (S1A, S1B, S1C) is closed, the three-phase AC voltage stabilizer of output voltage stabilization is reached.
[four] appended drawings 1 are the contactless high accuracy A. C. voltage stabilizer masters of single-phase continuous stepless of the present utility model Circuit.In Fig. 1:Master control bidirectional electronic switch S1 is made up of 4 diodes (D1~D4) and 1 triode (V1), and afterflow is two-way Electronic switch S2 is made up of 4 diodes (D5~D8) and 1 triode (V2), and inductance L and electric capacity C constitute wave filter, boosting Auto-transformer T boosts to the output voltage of alternating-current chopper circuit.
Accompanying drawing 2 is the contactless high accuracy A. C. voltage stabilizer depressor of three-phase continuous stepless of the present utility model.It is by 3 Fig. 1 The contactless high accuracy of three-phase continuous stepless of 3 shown single-phase continuous stepless contactless alternating current voltage stabilizer Y-connection compositions is handed over Flow voltage-stablizer.
[five] embodiment is from accompanying drawing 1:Unstable alternating voltage U21, through master control bidirectional electronic switch (S1) the voltage U41 after copped wave, then filtered through inductance (L) electric capacity (C), the alternating voltage U51 obtained at 5,1 two ends is handed over input The adjustable voltage of voltage U21 same waveforms is flowed, this voltage U51 does step-up auto-transformer (T) centre tap (5) and termination (1) AC-input voltage, two terminations of auto-transformer (T) (3,1) just obtain boosting output AC voltage.The utility model The output voltage of auto-transformer (T) be single-phase 220 volts, and the auto-transformer (T) two in CN203840206.U bulletins The ceiling voltage of termination is input ceiling voltage.If maximum input voltage is also 260V, i.e., the self coupling in the utility model becomes Depressor can save 40V windings than previous utility model patent, and 2 bidirectional electronic switch and its control circuit cost are identical. Thus, the single-phase contactless high accuracy A. C. voltage stabilizer cost of continuous stepless of the present utility model is lower, cost performance is higher.
It should particularly point out:2 end U31 alternating voltage 220V are exported by auto-transformer (T), are to export 2 terminal voltages by it to bear Feedback automatically controls the realization of bidirectional electronic switch (S1) make-to-break ratio, the make-to-break ratio of chopper circuit must place restrictions in maximum and Between 1.
From accompanying drawing 2:The three-phase continuous stepless that it is made up of 3 main circuit Y-connections of accompanying drawing 1 is contactless high-precision Spend AC voltage regulator main circuit.It has 1 exchange input and AC voltage-stabilizing output public zero curve (N), 3 three-phase alternating current inputs (A1, B1, C1) and 3 three-phase alternating current output ends (A2, B2, C2), the stable alternating voltages and three of three-phase 380V can be exported simultaneously The individual single-phase 220V for having public zero curve (N) stablizes alternating voltage, and they are by three-phase output AC voltage negative-feedback signal electricity Pressure, automatically controls the mesh that three-phase bidirectional electronic switch make-to-break ratio reaches the voltage stabilizing of output voltage.
The utility model has the advantages that simple in construction, continuous stepless, contactless, precision are high, and they are existing medium and small work( Rate alternating current steady voltage plug renewal product.The AC voltage regulator quantity of Wenzhou business men production middle low power family expenses carbon brush pressure regulation is very Greatly, AC voltage regulator performance indications can be improved by implementing the utility model, and economic benefit and social benefit can be produced after implementation.
