Description
Technical field
The utility model relates to a kind of voltage stabilizer, especially refers to a kind of non-contact voltage stabilizer of input voltage wide region.
Background technology
The most conventional voltage stabilizer has two kinds of working methods to reach voltage stabilizing work at present, is respectively compensated voltage regulator and autocoupling type voltage stabilizer.Wherein compensated voltage regulator, changes input voltage by the size and Orientation that changes bucking voltage on compensator transformer, and the mode that reaches voltage stabilizing output is modal working method in voltage stabilizer industry.What autocoupling type voltage stabilizer adopted is that input voltage connects the plane regulating of carbon brush at autotransformer, and output voltage is fixed, and realizes output voltage stabilizer by changing input and output voltage turn ratio.No matter be compensated voltage regulator or autocoupling type voltage stabilizer, its input voltage range relative narrower, and existing market has larger demand to the input voltage of wide region, and voltage stabilized range is had to the demand of deflection low pressure.Can not finely meet the wide region voltage stabilizing demand of this deflection low pressure according to existing voltage regulation way on market, as realize input voltage range 100V-260V, voltage stabilizing output 220V, if while adopting compensated voltage regulator to realize wide region voltage stabilizing, the in the situation that of low pressure 100V, need to compensate 120V, due to the symmetry of compensation high-low pressure, there is waste in high-end voltage stabilized range 260V-340V; If adopt autocoupling type voltage stabilizer expense larger, and band carries and realizes voltage stabilizing to 220V in the situation that of low pressure 100V, larger to the power requirement of transformer, current voltage stabilizing working method is difficult to realize the requirement of full power with work, so can not meet the wide region voltage stabilizing demand of this deflection one end well.
Summary of the invention
The purpose of this utility model is to provide a kind of non-contact voltage stabilizer of wide region.
For achieving the above object, the solution that the utility model is taked is: a kind of non-contact voltage stabilizer of wide region comprises 1 compensator transformer T1,1 step-up transformer T2,4 IGBT, 4 controllable silicons, 1 electric capacity and 1 inductance, the live wire L of input voltage is by one end of compensator transformer T1 secondary, another termination voltage regulating module circuit of compensator transformer T1 secondary, and receive the middle a certain fixed taps of step-up transformer T2, an end of step-up transformer T2 ceiling voltage is received output fire line terminal; Input civil power zero line N is connected with the other end of step-up transformer T2, as the working zero line of step-up transformer T2 and complete machine; Regulate the former limit input size of compensator transformer T1 according to 4 IGBT in actual conditions control voltage regulating module circuit and 4 silicon controlled conductings or cut-off, thereby regulate the bucking voltage △ U of secondary, realize first order voltage stabilizing output U ', after first order voltage stabilizing output, again boost voltage stabilizing to the output voltage values needing by step-up transformer T2.
By controlling 4 IGBT and 4 silicon controlled conductings or ending the bucking voltage value that changes T1, change the value of △ U, obtain first order voltage stabilizing output U '=Ui ± △ U, U ' after first order voltage stabilizing boosts by step-up transformer T2, adopt the ratio realization of autotransformer input number of turn n1 and output number of turn n2 to boost, final voltage stabilizing output Uo=n2/n1*U '.If bucking voltage scope is 80V, first order voltage stabilizing output valve is 180V, by the step-up transformer 40V that boosts, and final voltage stabilizing output 220V, when design load meets input voltage range 100V-260V, output voltage is 220V.Adopt the design's principle, can adjust according to practical application the bucking voltage scope of compensator transformer T1, if compensation range can be 20V-100V, first order output voltage U ' can be within the scope of 160V-200V, the voltage of step-up transformer T2 is set again, if boost value is within the scope of 20V-60V according to practical application.
