A common method is the distributed zero-controlled blood straight-line phase control. The two (four) modes are output drive voltages in units of full waves or waves. Please refer to Figure 3, taking the 5 system as an example. The maximum drive voltage interrupt frequency is output = 50% (Fig. 2). At this time, the interrupt frequency is L. See 4~6 Figure, in linear phase = column, when non-full power operation output, the output drive voltage is the voltage per positive phase angle as the voltage rotation size change. The current method has a phenomenon in which white waves are excessive. However, the driving voltage outputted by the power regulating device is currently outputted in a positive or negative half angle or a continuous interruption of the driving voltage, which causes a large amount of (four) wave interference, which causes damage to the device. Therefore, the service life of the m electronic device itself or the use efficiency of the device is a problem to be solved. SUMMARY OF THE INVENTION In view of the above problems of the prior art, the object of the present invention is to provide a low spectral power quality control method to solve the problems caused by harmonics. / In accordance with the purpose of the present invention, it is proposed that the low-harmonic power quality control system includes a resistive negative health, a - device, and a power _ " peripheral device. The resistive load device receives the drive voltage and performs the relative operation 'operation to generate the feedback signal according to the characteristics measured by the rugged carrier device (4). Temperature, stiffness, or pressure can be included in the characteristics that can be extracted. After the feedback signal is sent to the detecting device by the resistive negative residual, the device will feedback the Dfi and convert it into the control signal. After the control signal (4) is transmitted to the power adjustment device, the average value of each control signal received in the interval is calculated. According to the average value, the corresponding driving voltage is output in the second time interval. The interval includes continuous output ♦=inter- _ and continuous non-output time interval, and the average value of the control signal is matched with the ratio of the continuous output time interval and the continuous non-output time interval. The continuous output is continuously output in the continuous output time interval. Power drive, voltage 'stops the output of full power drive voltage at continuous output time interval. Thus, the minimum harmonic is generated for the overall power system. One of the 'power adjustment devices include trigger unit, microcomputer processing, power supply sapon, and loss The human signal unit is configured to receive a trigger signal for the microcomputer to process the single-it output, and output the multi-phase voltage signal as the driving voltage according to the trigger signal. The power supply unit is configured to provide the power required for the power adjustment 201128897. Signal unit is a percentage control that receives each control signal and converts its 77 to high and low potentials. After the signal, the microcomputer processing unit. The microcomputer processing unit calculates the average value of the low-potential percentage control signal for a fixed time, and generates a trigger signal according to the average value. The trigger signal distributes the ratio of the interval between consecutive output time intervals. The full-power trigger signal is output during the continuous output time, and the full-power trigger signal is outputted continuously without outputting the time interval. Method 2 The purpose of the invention is to propose a low-spectrum power quality control load device to generate feedback signals to the detector. After measuring and receiving at least one feedback signal, the device will change the feedback signal to the control signal and output it to the power adjustment device. The average value of the electric power adjustment device: the power adjustment device at the second time ^ = 2 control* Wei's average material voltage. The second time interval includes the continuous output time interval and continuous output when the output is not separated, and according to the ratio, continuously output the full power drive voltage at the continuous output time interval without outputting the time interval. Output unit: source = modulation =: touch processing 3 =: input _ signal, and according to the second power supply required . The input signal unit receives each control = 201128897 and converts it to a high and low percentage control signal, and then transmits it to the microcomputer to process the Zhuoyuan. The microcomputer processing unit calculates the average value of the high and low potential control signals in the fixed time gate, and generates a trigger signal according to the average value. This trigger signal distributes the ratio of the continuous output time interval to the continuous non-output time interval. Continuously output the full power trigger signal during the continuous output time in a fixed time, and stop outputting the full power trigger signal during the continuous output time. τ According to the above, the low harmonic power quality control system and method thereof according to the present invention have the following advantages: The low harmonic power quality control system and the method for lowering the harmonic power quality can be scaled by The method outputs the full-rate driving voltage at the continuous output time interval, and stops the driving voltage at the continuous output time interval, thereby reducing the generation of harmonics.

In the figure, the low harmonic power quality control system includes a detecting device 20, a power adjusting device 2〇2, and a resistive load device 2〇3. The detecting device 20 receives the feedback signal of the resistive load device 2〇3 and outputs a control signal to the power adjusting device 202. The power adjusting device 2〇2 outputs different power to the resistive load device 2〇3 according to the control signal.

The power supply unit 301 provides power required for the power adjustment device. The input signal unit 302 can receive a control signal of voltage or current. The voltage signal is 0V~5V, IV~5V, 0V~10V, 2V~10V, and the current signal is 0mA~20mA or 4mA~20mA. If the control signal is current, the input signal unit 302 converts the current signal into a voltage signal and outputs it. The input signal unit 302 converts the control signal to output a percentage control signal of the high and low potentials to the microcomputer processing unit 305. The percentage control signal of the high and low potentials includes a control signal that has been converted from a current to a voltage signal and a control signal that is originally a voltage signal. The over temperature detecting unit 304 measures whether the temperature in the power adjusting device is higher than a preset value. When the preset value is exceeded, an over temperature control signal is sent to the microcomputer processing unit 305, and the microcomputer processing unit 305 starts a fan. The fan is located on one side of the low harmonic power quality control system. The trigger unit 306 receives the trigger signal sent by the microcomputer processing unit, turns on the multi-phase voltage signal after triggering the complex array rectifier according to the trigger signal, and outputs the multi-phase voltage signal as the driving voltage. Each of the rectifiers in this complex array rectifier contains two anti-parallel controlled rectifiers. The zero phase detecting unit 303 detects the zero position of the multiphase voltage signal and outputs it to the microcomputer processing unit 305. When receiving the high and low potential control signals, the microcomputer processing unit 305 sends the trigger signals according to the average of all the high and low potentials received at a time interval of 201128897.
