Description

[0001] CYCLIC VOLTAGE DIVIDER AND OPERATING METHOD THEREOF [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a voltage divider, and more particularly, to a voltage divider capable of providing a standard voltage using a plurality of resistors constituting a closed circuit.

Calibrating the voltage meter is essential to maintain the intended measurement performance normally. It is essential to compare and correct the difference between the specified reference value and the measured value. The instrument used shall be capable of providing accurate reference values defined in the International System of Units (SI).

For electrical measurements, a quantum effect standard, called the Josephson voltage standard, is being used as a means of accurately implementing the standard voltage. However, since the limit of the voltage level is only 10V, a voltage divider is used to extend the usable range to 1000V. Among them, a resistor type distributor is generally used.

In the case of a general resistor type distributor, a plurality of resistors are connected in series, an input voltage is applied, and a resistance is distributed. However, even if a resistor is manufactured to have a specific resistance value, an error may occur depending on the manufacturing process. In addition, the actual magnitude of the resistance may vary from the desired value due to various factors such as the magnitude of the test current, the magnitude of the input voltage, the ambient temperature, the pressure, and the humidity. Therefore, even if a specific experiment is performed using a resistor divider, the error may be significant. In addition, correcting these errors is a difficult task that requires considerable effort and time.

Therefore, it is important to develop a voltage divider that can provide a standard voltage defined by an international system of units with little error.

It is an object of the present invention to provide a distribution voltage having an accuracy approximately equal to the standard voltage defined by the international system of units by accurately dividing the input voltage irrespective of the variation of the resistance value.

Another object of the present invention is to provide an input voltage value with almost the same accuracy as a standard voltage, using experimental values using a voltage distributed from an unknown input voltage.

The cyclic voltage divider according to an embodiment of the present invention includes first to n + 1 resistors sequentially connected in series to form one closed circuit, wherein the first to the (n + 1) Wherein an input voltage is applied across an input subset resistor comprising at least one resistor connected thereto and wherein the cyclic voltage divider comprises an output comprising an at least one resistor that is sequentially connected among the remaining resistances except for the input subset resistor, Selecting the output subset resistors so that a divided voltage is output across the subset resistors and sequentially moving both ends of the input subset resistors and both ends of the output subset resistors to the next resistors, Repeatedly outputting the divided voltage at both ends of the resistor, and comparing the divided voltage values From can be used to calculate the value of standard output voltage, or to calculate the value of the input voltage from the average of the distribution voltage.

In an embodiment, the value of the standard output voltage may be an arithmetic mean, a trimmed mean, a weighted mean, a geometric mean, a harmonic mean, ). ≪ / RTI >

As another embodiment, the apparatus may further include a first active guard circuit to an (n + 1) -th active guard circuit disposed around the first resistor to the (n + 1) th resistor.

As another embodiment, the apparatus may further include a rotary switch for rotating the first resistor to the (n + 1) th resistor.

According to an embodiment of the present invention, a method of operating a cyclic voltage divider including first to n + 1 resistors sequentially connected in series to form one closed circuit includes: Selecting an input subset resistor comprising at least one resistor connected in series among the resistors connected in series among the remaining resistances except for the input subset resistor, Applying an input voltage to both ends of the input subset resistor and obtaining a value of a distribution voltage that is a voltage across the output subset resistor; comparing both ends of the input subset resistor and both ends of the output subset resistor To the next resistor to sequentially subtract the value of the divided voltage across the output subset resistor from the half Steps of ever obtained, and may include the step of calculating the value of standard output voltage from the average of the distribution voltage value, or calculate the value of the input voltage from the average of the distribution voltage.

In an embodiment, the value of the standard output voltage is selected from the group consisting of an arithmetic mean, a trimmed mean, a weighted mean, a geometric mean, a harmonic mean, harmonic mean, or median.

According to an embodiment of the present invention, by using a cyclic voltage divider, a standard of a certain ratio between two voltages can be implemented, and using this, standard voltages defined in the international system of units can be extended .

It is to be understood that both the foregoing general description and the following detailed description are exemplary and should provide a further description of the claimed invention. Reference numerals are shown in detail in the preferred embodiments of the present invention, examples of which are shown in the drawings. Wherever possible, the same reference numbers are used in the description and drawings to refer to the same or like parts.

Although the terms "first "," second "and the like can be used herein to describe various elements, these elements are not limited by these terms. These terms may only be used to distinguish one element from the other. Accordingly, terms such as first element, section, and layer used in this specification may be used as a second element, section, layer, etc. without departing from the spirit of the present invention.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings so that those skilled in the art can easily carry out the technical idea of the present invention.

1 is a schematic view of a cyclic voltage divider 100 according to an embodiment of the present invention. The cyclic voltage divider 100 may include a plurality of resistors R 1 to R n + 1 and a rotary switch 110. For convenience of explanation, the plurality of resistors R 1 to R n + 1 and the rotary switch 110 have been abbreviated.

Referring to FIG. 1, R 1 to R n + 1 are sequentially connected in series, and R 1 and R n + 1 are connected to each other to form one closed circuit. Although not shown in the figure, at least one terminal for measuring the voltage or applying the power supply voltage may be provided to the node between each of the resistors.

Rotary switch 110 is provided in the center of the closed circuit forming the R 1 to R n + 1 can be rotated for R 1 to R n + 1. For example, the rotary switch 110 may rotate 360 / (n + 1) degrees of R 1 to R n + 1 in one switching operation.

According to the cycle type voltage divider according to the embodiment of the present invention, experimental results obtained by distributing the power source voltage with almost no error can be obtained. Hereinafter, an operation method of the cyclic voltage divider will be described in detail with reference to FIGS. 2 to 8. FIG.

FIGS. 2 and 3 are views schematically showing a method of operating the cyclic voltage divider 100 according to the embodiment of the present invention.

First, referring to FIGS. 2 and 3, a case will be described in which a standard output voltage divided from a power source voltage is generated by using the cyclic voltage divider 100. FIG.

The power supply voltage 130 may be applied to both terminals of R n + 1 . As a result, it takes a voltage of Vs to R n + 1, R to take the voltage of Vs of the positive terminal 1 to R n. If R 1 to R n + 1 have resistance values of the same magnitude, the voltage across R 1 will be 1 / n x V s. However, even if R 1 to R n + 1 are fabricated to have the same resistance value, it is possible to reduce the resistance value of the battery by various reasons (for example, the magnitude of the input voltage, the size of the test current, Thus, R 1 to R n + 1 may have finer resistances of different sizes. In this case, by connecting the voltage measuring instrument 150, to both terminals of R 1, to measure the magnitude of the voltage across R 1. Let the magnitude of the voltage measured at R 1 be V 1 .

Then, as shown in FIG. 3, the terminal to which the power supply voltage 130 and the voltage meter 150 are connected is replaced. The terminal may be manually replaced, but the terminal to which the power supply voltage 130 and the voltage meter 150 are connected may be automatically changed using the rotary switch 110. The rotary switch is obvious to a person having ordinary skill in the art to which the present invention belongs, so the detailed configuration and explanation will be omitted.

As the terminal is changed, a voltage of Vs is applied to R 1 , and a voltage of Vs is applied to R 2 to R n + 1 . Theoretically, the voltage across R 2 is 1 / n × Vs, but errors can occur due to various reasons such as the ambient temperature, the magnitude of the voltage applied to the resistor, and so on. Let V 2 be the magnitude of the voltage measured at R 2 .

While continuously rotating the rotary switch 110, the voltages at R 3 to R n + 1 are sequentially measured. Let the magnitudes of the voltages measured in R 3 to R n + 1 be V 3 to V n + 1 , respectively. The average value of the voltages V 1 to V n + 1 measured by the voltage meter 150 becomes a value very close to the standard output voltage with little error. For example, the average value may be calculated using any one of an arithmetic mean, a trimmed mean, a weighted mean, a geometric mean, a harmonic mean, or a median Lt; / RTI > In this embodiment, the case where the calculation is performed according to the arithmetic mean will be described as an example.

More specifically, when the average number of the results of the specific experiments to be performed using the voltages V 1 to V n distributed by the cyclic voltage divider 100 and the results of the respective experiments are obtained, This will be very close to the experimental results using the standard voltage defined in the International System of Units (SI) (ie, a voltage having a magnitude exactly 1 / n times the input voltage).

In this embodiment, it has been described that the terminal to which the input voltage Vs is applied varies as well as the terminal at which the voltage is measured while the rotary switch 110 is rotated. However, according to the embodiment, the terminal to which the input voltage Vs is applied (that is, both terminals of R n + 1 ) does not change, only the terminal (i.e., both terminals of R 1 to R n ) Can change.

Conversely, a case where an output voltage divided from an unknown power supply voltage is measured to generate a standard input voltage will be described.

2 and 3, an unknown power supply voltage 130 may be applied to both terminals of R n + 1 . As a result, it takes a voltage of Vs to R n + 1, R 1 through R n to take the voltage of Vs. If R 1 through R n + 1 have the same magnitude of resistance, then the voltage across R 1 will be 1 / x Vs. However, even though R 1 to R n + 1 are fabricated to have the same resistance value, R 1 to R n + 1 may have minutely different resistances for various reasons. In this case, by connecting the voltage measuring instrument 150, to both terminals of R 1, to measure the magnitude of the voltage across R 1. Let the magnitude of the voltage measured at R 1 be V 1 .

Then, as shown in FIG. 3, the terminal to which the power supply voltage 130 and the voltage meter 150 are connected is replaced. The terminal may be manually replaced, but the terminal to which the power supply voltage 130 and the voltage meter 150 are connected may be automatically changed using the rotary switch 110.

As the terminal is changed, a voltage of Vs is applied to R 1 , and a voltage of Vs is applied to R 2 to R n + 1 . Theoretically, the voltage across R 2 is 1 / n × Vs, but errors can occur due to various reasons such as the ambient temperature, the magnitude of the voltage applied to the resistor, and so on. Let V 2 be the magnitude of the voltage measured at R 2 .

While continuously rotating the rotary switch 110, the voltages at R 3 to R n are sequentially measured. Let the magnitudes of the voltages measured in R 3 through R n be V 3 through V n , respectively. The average value of the voltages V 1 to V n measured by the voltage meter 150 becomes a value very close to the standard output voltage with little error.

Therefore, when the average value of the experimental results is obtained after performing a specific experiment to be performed using V 1 to V n , the result of the experiment using the output voltage having a magnitude of exactly 1 / n times the unknown power supply voltage Lt; / RTI > And, n times of the average value of the experimental results will be the result of the experiment using the unknown standard input voltage.

The reason why the experiment is performed using the distributed voltage without performing the experiment directly using the unknown power supply voltage is that there may be various restrictions in the experiment such as the power supply voltage size, the performance of the measuring instrument, and the experimental environment . Therefore, if the cyclic voltage divider according to the embodiment of the present invention is utilized, not only these limitations can be solved, but highly accurate experimental results such as the experiment using the standard voltage can be directly obtained.

4 and 5 are views schematically showing a method of operating the cyclic voltage divider 100 according to another embodiment of the present invention.

4 and 5, a case will be described in which a standard output voltage divided by a ratio of 2 / n from a power supply voltage is generated using a cyclic voltage divider 100. FIG.

The power supply voltage 130 may be applied to both terminals of R n + 1 . As a result, it takes a voltage of Vs to R n + 1, R 1 through R n to take the voltage of Vs. If R 1 through R n + 1 have a resistance value of the same magnitude, the voltage across the first subset resistors R 1 and R 2 will be 2 / n x Vs. However, even though R 1 to R n + 1 are fabricated to have the same resistance value, R 1 to R n + 1 may have minutely different resistances for various reasons. At this time, the first sub-set resistance by connecting a voltage measuring instrument 150 is provided on both ends of the (R 1 and R 2), a first subset of the resistance (R 1 and R 2) measure the voltage of the both ends. Let the magnitude of the voltage measured across the first subset resistors R 1 and R 2 be V 12 .

Then, as shown in FIG. 5, the terminal to which the power supply voltage 130 and the voltage meter 150 are connected is replaced. The replacement of the terminals can be performed by manual or rotary switch 110.

As the terminal is changed, a voltage of Vs is applied to R 1 , and a voltage of Vs is applied to R 2 to R n + 1 . Theoretically, according to the change of the terminal, the voltage of Vs is applied to R 1 , and the voltage of Vs is also applied to R 2 to R n + 1 . Theoretically, the voltage across both ends of the second subset resistors R 2 and R 3 is 2 / n × Vs, but an error may occur due to various reasons such as the ambient temperature, the magnitude of the voltage applied to the resistor, and the like. Let the magnitude of the voltage measured across the second subset resistors R 2 and R 3 be V 23 .

Sequentially measures the voltages across the nth subset resistors R n and R n + 1 from the third subset resistors R 3 and R 4 while continuing to rotate the rotary switch 110. Let the magnitudes of the voltages measured across the nth subset resistors R n and R n + 1 from the third subset resistors R 3 and R 4 be V 34 to V n (n + 1) , respectively. The average value of the voltages V 12 to V n (n + 1) measured by the voltage meter 150 becomes a value very close to the standard output voltage with little error.

More specifically, the number of specific experiments to be performed using each of the voltages V 12 to V n (n + 1) distributed by the cyclic voltage divider 100, , This would be very close to the result of the experiment using the standard voltage defined in the SI (ie, a voltage having a magnitude exactly 2 / n times the input voltage).

Conversely, the cycle type voltage divider 100 may be used to measure the output voltage divided from the unknown power supply voltage to generate a standard input voltage. At this time, the output voltage will be 2 / n times the unknown power supply voltage. A specific operation method for this operation is similar to that described above with reference to FIG. 2 and FIG. 3, so that a duplicate description will be omitted.

4 and 5, the output voltage has a magnitude of 2 / n times the power supply voltage. However, the number of resistors constituting the subset resistor can be expanded. For example, assuming that the number of the resistors constituting the input subset resistors is two and the number of the resistors constituting the output subset resistors is three, the first subset resistors R 1 to R 3 to n-2 The experiment can be performed by measuring the voltages across the subset resistors R n + 1 to R 2 , respectively.

6 is a schematic diagram illustrating a method of operating the cyclic voltage divider 200 according to another embodiment of the present invention.

6, the cyclic voltage divider 200 includes a plurality of resistors R 1 to R n + 1 , a rotary switch 210, and a plurality of active guard circuits GC 1 to GC n + 1 ).

Since the plurality of resistors R 1 to R n + 1 and the rotary switch 210 are substantially the same as those described above, the overlapping description will be omitted.

Each of the plurality of active guard circuits (GC 1 to GC n + 1 ) may be arranged as shown in the figure around a plurality of resistors R 1 to R n + 1 . The active guard circuit may include circular conductive rings 220-1 through 220- (n + 1) as shown. Each of the circular conductive rings 220-1 to 220- (n + 1) may be disposed around a node between the resistance and the resistance, as shown in the figure, to maintain the potential of the node at a constant level. For example, when as shown in the figure, the resistor (R n + 1) the power supply voltage 230 is applied, across the active guard circuit (GC n + 1) is a resistor (R n + 1) to cut off the leakage current So that the voltage can be kept constant at Vs. Likewise, connected active guard circuits GC 1 to GC n + 1 and circular conductive rings 220-1 to 220- (n + 1), which are arranged around each of a plurality of resistors R 1 to R n , Allows the voltage at both ends of each of the plurality of resistors R 1 to R n to be maintained constant (i.e., a voltage of 1 / n times of Vs). As a result, the same results as those obtained by performing the experiment using a more accurate, standard voltage can be obtained.

Even if the active guard circuit is added to constitute the cyclic voltage divider 200, the basic principle and the operation method are substantially the same as those described above, and thus a duplicate description will be omitted.

According to the embodiment of the present invention, by accurately dividing the input voltage using the cyclic voltage divider, very accurate experimental results such as the experiment using the standard voltage defined in the International System of Units (SI) can be obtained.

7 is a schematic view illustrating a method of operating the cyclic voltage divider 200 according to another embodiment of the present invention.

In step S110, among the plurality of resistors R 1 to R n + 1 constituting the closed circuit, an input subset resistor including at least one resistor connected in series may be selected. For example, if the input subset resistors include one resistor, the ( n + 1 ) th resistor R n + 1 may be selected as the input subset resistor.

In step S120, an output subset resistor may be selected that includes at least one resistor that is sequentially connected (R 1 to R n ) out of the resistances other than the input subset resistor R n + 1 . For example, if the output subset resistors include two resistors, then R 1 and R 2 will be selected as the first output subset resistors.

In step S130, it may be a subset of the input resistance of the voltage across the (R n + 1) is the input voltage (Vs) to the opposite ends and a first output subset resistance (R 1 and R 2) obtained. For example, the value of the voltage across the first output subset resistors R 1 and R 2 may be measured by a meter or the like, or utilized for another measurement.

In step S140, it can be determined whether or not the voltage across both sub-resistors (i.e., R 1 R 2 , R 2 R 3 ... R n-1 R n , . A motion branch may occur according to the determination result. If the measurement is completed (Yes), step S150 is executed. Otherwise (No), the step S160 is executed.

In step S150, the value of the standard output voltage can be calculated from the average of the measured distribution voltages. The calculation of the average value may be performed by any one of an arithmetic mean, a trimmed mean, a weighted mean, a geometric mean, a harmonic mean, or a median But is not limited thereto.

For example, if you want to obtain the same results as those performed by using the standard output voltage specified in the International System of Units, you can perform experiments using voltages across the subset resistors. And, when the average value of the experimental results is obtained, there will be almost no error as the experiment performed using the standard output voltage.

Or conversely, the value of the unknown input voltage can be calculated from the calculated average value.

In step S160, the positions of both ends of the input subset resistor and both ends of the output subset resistor can be moved to the next resistor, respectively. That is, R 1 is selected as the input subset resistor, and R 2 and R 3 can be selected as the output subset resistor. Thereafter, step S130 is executed so that the divided voltage applied across all subset resistors (i.e., R 1 R 2 , R 2 R 3 ... R n-1 R n ) can be measured.

For example, if you want to obtain the same results as those performed by using the standard input voltage specified in the international system, the experiment is first performed using the voltages across the subset resistors. Then, the average value of the experimental results is obtained. From the average of the experimental results, we can obtain the experimental results using the standard input voltage. For example, if the subset resistance consists of two resistors, multiplying the average value of the experimental results by n / 2 will be approximately the same as the experimental result using the standard input voltage.

The reason why the experiment is performed using the distributed voltage without performing the experiment directly using the unknown power supply voltage is that there may be various restrictions in the experiment such as the power supply voltage size, the performance of the measuring instrument, and the experimental environment . Therefore, if the cyclic voltage divider according to the embodiment of the present invention is utilized, not only these limitations can be solved, but highly accurate experimental results such as the experiment using the standard voltage can be directly obtained.

The detailed description of the present invention has been provided for specific embodiments. However, it is needless to say that the present invention can be modified into various forms without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the above-described embodiments, but should be determined by the scope of the claims of the present invention as well as the claims of the present invention.
