- the power supply unit 100 uses AC power coming from the power line.
- the electricity transmitted from the distribution substation (secondary substation) is lowered to the low voltage of the distribution through a transformer, and is then sent to a building or a factory, or to a column transformer through a distribution line. Again, the voltage is reduced to, for example, about 220 to 380 volts to supply the home. Therefore, the power supplied to the power supply unit 100 of the present invention may be a commercial power source generally used. However, this is for illustrative purposes and the present invention is not limited thereto.
- the sensor unit 110 is positioned between the power supply unit 100 and the power regulator 130 to sense a current flowing from the power supply unit 100 toward the power regulator 130. That is, the sensor unit is provided with a current sensor. Of course, it is also possible to sense the voltage by placing the voltage sensor 111 without sensing the current. Therefore, the sensor unit 110 detects current or voltage, or simultaneously detects current and voltage and transmits the detected value to the controller 120.
- the power input to the power regulator 130 has been described in the drawings, but it is also possible to sense the power output from the power regulator 130. Of course, at this time, it is also possible to detect current or voltage, or to simultaneously detect current and voltage.

- the controller 120 receives data regarding the current or voltage sensed from the sensor unit 110, compares the data with the set data, and when the measured current or voltage is higher or lower than the preset value.
- the power is controlled by transmitting a control signal to the power regulator 130 and transmits the information regarding the above control process to the second transceiver 150 through the first transceiver 140. This power adjustment process will be described later with reference to the flowchart shown in FIG. 6.
- the power regulator 130 receives a command from the controller 120, and increases or decreases the voltage to provide stable power to the load 170.
- the power regulator 130 may receive power from the power supply unit 100.
- FIG. 2 a circuit diagram for performing a process of boosting or depressurizing a voltage is shown in FIG. 2. This will be described later with reference to FIGS. 2 to 5.

- Wireless communication such as infrared communication, may be used.
- the first transceiver 140 receives data regarding the current or voltage sensed by the controller 120 and transmits the data to the second transceiver 150 or a value set by the user from the remote monitoring controller 160. Information such as a change value is received from the second transceiver 150.
- the remote monitoring controller 160 provides a user with information about whether the power control is being stably performed in real time based on the information transmitted from the controller 120. To this end, the remote monitoring control unit 160 is also provided with a microprocessor and a memory, where data and programs are stored, through which a remote monitoring algorithm is executed.
- a display device may be attached for the user's convenience.
- the input device may be provided to change based on the transmitted data.

- the first tab 132, the second tab 133, and the third tab 134 are respectively primary
- the first switch S1, the second switch S2, and the third switch S3 are connected to the predetermined points of the windings, and the switches are connected to the common line 183 to correspond to each of the taps.
- the switches S1, S2, and S3 may be implemented by, for example, a circuit such as a relay, a TRIAC, an SCR, an IC, and the like so as to operate a switching operation.
- the voltage applied to the primary winding number N1 becomes V1
- FIG. 4. 4 is an equivalent circuit diagram when the second switch S2 is closed in the power regulator of FIG. 2. That is, when the second switch S2 connected to the second tab 133 is closed, the second tap 133 is connected to the common line 183, and thus, the primary winding number N3 and the secondary winding number ( N4) is generated.
- V1 and V2 are different from voltages applied to the first tap 132 when the first switch S1 described above is closed. As shown, since the number of turns is different, the voltage input to it is different and the voltage output is different. Of course, in the case of the third switch S3 and the third tap 132 which will be described later, the input voltage and the output voltage are different.
- the secondary winding number N4 is configured in proportion to the primary winding number N3, and the secondary winding number N4 is excited by the primary winding number N3, thereby generating an output voltage V2.
- a diagram showing this is shown in FIG. 4.
- FIG. 5 is an equivalent circuit diagram when the third switch S3 is closed in the power regulator of FIG. 2. That is, when the third switch S3 connected to the third tap 134 is closed, the third tap 134 is connected to the common line 183, and thus, the primary winding number N5 and the secondary winding number ( N6) is generated.
- the voltage applied to the primary winding number N5 becomes V1

- the second switch S2 when the second switch S2 is closed, the secondary Less power is delivered to the windings, and less power is delivered to the two-side windings when the third switch S3 is closed.
- the present invention is capable of finer power adjustment since both the number of primary windings and the number of secondary windings are changed. That is, as described above, the winding ratio is precise and fine, such as 0.88, 0.87.
- the secondary winding should be accurately wound. For example, in order to achieve a ratio of 0.88, the secondary winding must be wound to the number of secondary windings 8.8 to the primary winding number 10, which is difficult to manufacture and requires excessively fine work.
- the present invention is composed of three taps and three switches connected thereto, this is for understanding the present invention, and it is also possible to configure more taps and switches.
- FIGS. 6 and 1. 6 is a flowchart illustrating a process of remotely controlling power by monitoring primary power in accordance with an embodiment of the present invention.

After that, step S620 is repeated again.
- step S620 determines whether the input power is smaller than the rated power.

It is maintained for a time (step S622). After that, step S620 is repeated again.
