[four] appended drawings 1 is that single-phase copped wave work of the present invention becomes compensation alternating current steady voltage plug main circuit.Accompanying drawing 2 is that three-phase copped wave work of the present invention becomes compensation alternating current steady voltage plug main circuit.
[five] embodiment is known by accompanying drawing 1: the triode (V1, V2) by 2 band diodes (D1, D2) forms master control bidirectional electronic switch (S1), triode (V3, V4) by another 2 band diodes (D3, D4) forms another master control bidirectional electronic switch (S3), by 2 unidirectional thyristors (V5V6), form afterflow electronic switch (S2), by another 2 unidirectional thyristors (V7, V8), form another 1 afterflow electronic switch (S4).Filter capacitor (C3) is to enter electrical network setting for reducing the harmonic wave of copped wave AC voltage adjusting circuit.Circuit working principle is as follows:
By master control bidirectional electronic switch (S1) and afterflow bidirectional electronic switch (S2), form copped wave AC voltage adjusting circuit, chopping voltage obtains power-frequency voltage through inductance (L) and electric capacity (C1) filtering, give power frequency compensator transformer (B) armature winding (W11) power supply, secondary winding (W2) induced voltage with exchange input 2 ends (1,2) voltage anti-series, the AC-input voltage of 2 ends (1,3) is exported in counteracting higher than AC voltage-stabilizing, reach the stable of output voltage.By another 1 master control bidirectional electronic switch (S3) and another 1 afterflow bidirectional electronic switch (S4), form another 1 and cut control AC voltage adjusting circuit, defeated wave voltage obtains power-frequency voltage through inductance (L) and electric capacity (C2) filtering, give power frequency compensator transformer (B) armature winding (W12) voltage, secondary winding (W2) induced voltage with exchange the series connection of input 2 ends (1,2) voltage forward, compensation exchanges the undertension of output 2 ends (1,3), reaches the stable of output voltage.When the voltage that exchanges input 2 ends equals AC voltage-stabilizing and exports the voltage of 2 ends, as long as by 2 afterflow electronic switches (S2, S4), zero triggering and conducting, the upper voltage drop of Industrial Frequency Transformer secondary winding (W2) is zero, and bucking voltage is also zero.It is just equivalent to the 7th bypass intergranular tube module in single-phase intelligent compensation alternating current steady voltage plug.
Contrast intelligent compensation type ac voltage stabilizer known with compensation type ac voltage stabilizer circuit diagram of the present invention: both use blocks current capacity identical, the present invention has reduced by 3 modules, because one of the IGBT module of same specification is only high by 1 than unidirectional intergranular tube module price, 5 times, therefore, the total price of 2 IGBT modules is certainly much lower than 5 unidirectional intergranular tube modules, and therefore, the total price ratio of the single-phase voltage stabilizing circuit of the present invention 4 modules used knows that 7 module total prices of energy type are much lower.The capacity of this bright compensator transformer of uniting with know can type identical, but many one-level armature windings, need to increase armature winding Yong Copper measures, but because the present invention saves tap voltage regulating transformer more than 1, the material cost of 1 compensator transformer of the present invention, far below the material cost of intelligent 2 transformers.Therefore, the present invention not only increases substantially in the technical performance acquisition of the aspects such as control precision height, and the more important thing is the cost that saves material, and improves profit, is more subject to the welcome of production unit, and it just will substitute intelligent compensation type ac voltage stabilizer.
From accompanying drawing 2: it is to become compensation AC voltage-stabilizing electricity by the single-phase copped wave work of 3 shown in accompanying drawing 1 to drench the main circuit that main circuit Y-connection forms that three-phase copped wave work of the present invention becomes compensation alternating current steady voltage plug, it has 1 to exchange input and public zero end (N) of AC voltage-stabilizing output, 3 three-phase alternating current input (A1, B1, C1) and 3 three-phase alternating current output end of pressure-stabilizing (A2, B2, C2), can export three single-phase 220V AC-AC burning voltages that three-phase 380V exchanges burning voltage and has public zero curve (N) simultaneously, with regulating 6 two-way full control electronic switch (S1A of master control, S3A, S1B, S3B, S1C, the control make-to-break ratio of cutting of the full control device S3C) regulates bucking voltage size, reach the three-phase ac regulated power supply of output voltage stabilization.The power frequency compensator transformer of three-phase ac regulated power supply can be 3 single phase industrial frequence compensator transformers, can be also the three-phase main-frequency compensator transformer of 1 armature winding and secondary winding Y-connection.
The present invention has that cost is low, power factor is high, harmonic wave is few, continuous stepless, contactless, precision advantages of higher, is the alternating current steady voltage plug renewal product that existing intelligent contactless AC voltage regulator and carbon brush regulate.
