[Background technology]

[0002] During the startup of electronic products, the cooperation of external electronic equipment is often required to provide a large current to start the operation of the electronic product, which may be, for example, a power supply or a source measure unit (SMU).

Therefore, the industry is in urgent need of finding a solution. Summary of the Invention

[0003] This summary is intended to provide a simplified summary of the disclosure so that the reader can have a basic understanding of the disclosure. This summary is not an exhaustive overview of the disclosure, and is not intended to pinpoint important / key parts of the embodiments of the disclosure or to limit the scope of the disclosure.

[0004] One technical aspect of the present disclosure relates to an adjustment control device for adjusting and controlling an output current peak value of an electronic device, the adjustment control device including: a first comparison circuit for comparing a first integral value in a first cycle of the output current with a first default value and generating a first comparison result when the first integral value is equal to or greater than the first default value; a second comparison circuit for comparing a second integral value in a second cycle of the output current with a second default value and generating a second comparison result when the second integral value is equal to or greater than the second default value; and a logic control circuit for outputting a reduction signal when receiving the first comparison result or the second comparison result, thereby reducing the output current peak value.

[0007] In one embodiment, the regulation control device further includes at least one integrator circuit, which is used to integrate the current absolute value of the output current to generate a first integral value in a first period, a second integral value in a second period, and a third integral value in a default period.

[0008] In one embodiment, the regulation control device further comprises a peak value adjustment circuit for receiving a decrease signal and generating a peak value adjustment signal to decrease the output current peak value of the output current, or for receiving an increase signal and generating a peak value adjustment signal to increase the output current peak value of the output current.

[0009] Another technical aspect of the present disclosure relates to a method for adjusting and controlling an output current peak value of an electronic device, the method including the steps of: comparing a first integral value in a first cycle of the output current with a first default value, and generating a first comparison result when the first integral value is equal to or greater than the first default value; comparing a second integral value in a second cycle of the output current with a second default value, and generating a second comparison result when the second integral value is equal to or greater than the second default value; and lowering the output current peak value by outputting a reduction signal in response to the first comparison result or the second comparison result.

[0010] In one embodiment, the adjustment control method further includes a step of comparing, after the default period, a third integral value in the default period of the output current with a third default value, and generating a third comparison result when the third integral value is smaller than the third default value, and a step of increasing the output current peak value by outputting an increase signal in response to the third comparison result.

[0011] In one embodiment, the method further includes a step of comparing a first integral value during a first period of the output current and a first default value, and taking an absolute value of the output current prior to the step of generating a first comparison result if the first integral value is greater than or equal to the first default value.

[0012] In one embodiment, the regulation control method further includes integrating a current absolute value of the output current to generate a first integral value in a first period, a second integral value in a second period, and a third integral value in a default period.

[0016] In order to more fully and completely describe the present disclosure, the following description is illustrative of the embodiments and specific examples of the present disclosure, but is not the only way to implement or apply the specific examples of the present disclosure. The embodiments include features of several specific examples and method steps and sequences for constructing and operating these specific examples. However, other specific examples may be used to achieve the same or equivalent functions and sequences of steps.

[0017] Unless otherwise defined herein, scientific and technical terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. Also, unless conflicting with context, the singular forms of nouns used herein include the plural forms of such nouns, and the use of the plural forms of such nouns also includes the singular form of such nouns.

[0018] As used herein, "coupled" may refer to two or more components being in direct physical or electrical contact with each other, or in indirect physical or electrical contact with each other, and may also refer to two or more components operating or operatively with each other.

[0019] Please refer to Figures 1A and 1B. Figure 1A shows a schematic diagram of an electronic device 10, a regulation control device 100, and an electronic product 200 according to an embodiment of the present disclosure, and Figure 1B shows a schematic diagram of the regulation control device 100 according to an embodiment of the present disclosure. As shown in the figure, the regulation control device 100 is used to regulate and control the output current peak value (i.e., the maximum current point of the output current) of the electronic device 10 to supply power from the electronic device 10 to the electronic product 200. The regulation control device 100 includes a first comparison circuit 150, a second comparison circuit 160, and a logic control circuit 180. The first comparison circuit 150 and the second comparison circuit 160 are coupled to the logic control circuit 180.

[0020] In operation, the first comparison circuit 150 is used to compare a first integral value in a first period of the output current with a first default value, and generate a first comparison result if the first integral value is equal to or greater than the first default value. The second comparison circuit 160 is used to compare a second integral value in a second period of the output current with a second default value, and generate a second comparison result if the second integral value is equal to or greater than the second default value. When the logic control circuit 180 receives the first comparison result or the second comparison result, it outputs a drop signal to drop the output peak value of the output current.

[0021] For example, when the electronic device is started, the output current of the electronic device at the power supply end is temporarily increased to be a starter for starting the electronic device. For a certain state in the present disclosure, the output peak value of the output current is high, and is set to, for example, 5V (volts). At this time, the switch 120 of the regulation control device 100 is switched to the side (lower side) of the first comparison circuit 150 and the second comparison circuit 160, and the first comparison circuit 150 and the second comparison circuit 160 judge whether the output peak value of the output current needs to be switched to low, thereby avoiding damage to the internal components of the power supply end.

[0022] The judgment condition of the first comparison circuit 150 is to judge whether or not the integral value of the output current is equal to or greater than a first default value in a first period. For example, the first comparison circuit 150 judges whether or not the integral value of the output current within 10 ms (milliseconds) is equal to or greater than a first default value. If the integral value of the output current is equal to or greater than the first default value, the first comparison circuit 150 generates a first comparison result.

[0023] The judgment condition of the second comparison circuit 160 is to judge whether the integral value of the output current is equal to or greater than the second default value in the second period. For example, the second comparison circuit 160 judges whether the integral value of the output current within 500 ms is equal to or greater than the second default value. If the integral value of the output current is equal to or greater than the second default value, the second comparison circuit 160 generates a second comparison result. It should be noted that the first default value and the second default value can also be set to be equal or unequal according to the actual needs of the present disclosure. For example, the first default value may be set to, but is not limited to, 60000A, and the second default value may be set to, but is not limited to, 60000*20A, that is, the second default value may be 20 times the first default value, but the time length is 50 times (500ms / 10ms).

[0024] When any of the above judgment conditions is met, the logic control circuit 180 receives the first comparison result transmitted from the first comparison circuit 150 or the second comparison result transmitted from the second comparison circuit 160, and at this time, the logic control circuit 180 outputs a drop signal to drop the output peak value of the output current, thereby avoiding damage to internal components of the electronic device at the power supply end.

[0025] In one embodiment, the regulation control device 100 further includes a third comparison circuit 170. The third comparison circuit 170 is coupled to the logic control circuit 180. After the default period, the third comparison circuit 170 compares a third integral value in the default period of the output current with a third default value, and generates a third comparison result when the third integral value is smaller than the third default value. When the logic control circuit 180 receives the third comparison result, it outputs an increase signal to increase the output peak value of the output current.

[0026] For example, the judgment conditions of the third comparison circuit 170 are to judge whether the duration exceeds the default period and to judge whether the integral value of the output current in the default period is less than the current default value. For example, the third comparison circuit 170 judges whether the duration reaches 500 ms, and after 500 ms, the third comparison circuit 170 judges whether the integral value of the output current within 500 ms is less than the default value. If the integral value of the output current is less than the default value, the third comparison circuit 170 generates a third comparison result. When the judgment conditions are achieved, the logic control circuit 180 receives the third comparison result and at this time outputs an increase signal to increase the output peak value of the output current.

[0027] In one embodiment, the regulation control device 100 further includes an absolute value circuit 110. Since the output current of the electronic device at the power supply end may be an AC current, the absolute value circuit 110 needs to take the absolute value of the current value of the output current to generate a current absolute value for subsequent integration operations. For example, the first comparison circuit 150, the second comparison circuit 160, and the third comparison circuit 170 may be used to compare a first integral value in a first period of the current absolute value with a first default value, a second integral value in a second period of the current absolute value with a second default value, and a third integral value in a default period of the current absolute value with a third default value, respectively.

[0028] In one embodiment, the regulation control device 100 further includes at least one integrating circuit, for example, a first integrating circuit 130 and a second integrating circuit 140. The at least one integrating circuit is used to integrate the current absolute value of the output current, for example, when the switch 120 is switched to the side (for example, the lower side) of the first comparing circuit 150 and the second comparing circuit 160, the first integrating circuit 130 generates a first integral value in a first period and transmits it to the first comparing circuit 150 for the subsequent comparison process, and the first integrating circuit 130 generates a second integral value in a second period and transmits it to the second comparing circuit 160 for the subsequent comparison process. When the switch 120 is switched to the side (for example, the upper side) of the third comparing circuit 170, the second integrating circuit 140 generates a third integral value in a default period and transmits it to the third comparing circuit 170 for the subsequent comparison process. In addition, the switch 120 may be set in advance to switch to the side (e.g., the lower side) of the first comparison circuit 150 and the second comparison circuit 160, and when the output peak value of the output current switches to low, the switch 120 switches to the side (e.g., the upper side) of the third comparison circuit 170, and then, when the output peak value of the output current switches to high, the switch 120 switches again to the side (e.g., the lower side) of the first comparison circuit 150 and the second comparison circuit 160.

[0029] In one embodiment, the regulation control device 100 further includes a peak value adjustment circuit 190 coupled to the logic control circuit 180. The peak value adjustment circuit 190 is used to receive a drop signal by the logic control circuit 180 and generate a peak value adjustment signal Sout to drop the output peak value of the output current. Alternatively, the peak value adjustment circuit 190 is used to receive an increase signal by the logic control circuit 180 and generate a peak value adjustment signal Sout to raise the output peak value of the output current. It should be noted that the present disclosure is not limited to the structure shown in FIG. 1B, and is merely an exemplary embodiment of the present disclosure to facilitate understanding of the technology of the present disclosure, and the claims of the present disclosure are based on the claims of the invention. Modifications and modifications made to the embodiments of the present disclosure by those skilled in the art without departing from the spirit of the present disclosure still fall within the scope of the claims of the present disclosure.

[0030] FIG. 2 shows a waveform diagram of relevant parameters of the regulation control device 100 shown in FIG. 1B according to an embodiment of the present disclosure. As shown in the figure, the output current of the power supply is Iout. The first integral value in the first period is Intel. The second integral value in the second period is Inte2. The peak value adjustment signal is Sout. In the first period 0S (seconds) to 0.01S (seconds), the first integral value Intel continues to rise, but after one first period, the first integral value Intel is not greater than or equal to the first default value, so the peak value adjustment signal Sout still remains at a high level. Also, since the first integral value Intel in the first period 0S to 0.01S is not greater than or equal to the first default value, the first integral value Intel is cleared thereafter, and the first integral value Intel is recalculated and recompared from another first period 0.01S to 0.02S, and so on. Assuming that the first integral value Intel is equal to or greater than the first default value in any first period, the peak value adjustment signal Sout is adjusted from high level to low level to lower the output peak value of the electronic device.

[0031] In the second period from 0S (seconds) to 0.05S (seconds), the second integral value Inte2 continues to rise. As can be seen from the figure, in the section from 0.03S to 0.04S, the second integral value Inte2 is equal to or greater than the second default value, so the peak value adjustment signal Sout is adjusted from high level to low level, thereby lowering the output peak value of the power supply. After the output peak value of the power supply is lowered, it can be seen that the output current Iout is limited to a low level from the section from 0.04S to 0.05S.

[0032] FIG. 3 shows a waveform diagram of relevant parameters of the regulation control device 100 shown in FIG. 1B according to an embodiment of the present disclosure. As shown in the figure, the output current of the power supply is Iout. The third integral value in the default period is Inte3. The count value is Tcount, for example, 1count is 10us. The peak value adjustment signal is Sout. After the default period 0S~0.05S, it is determined whether the third integral value Inte3 is smaller than the third default value. As can be seen from the figure, even if the default period 0S~0.05S continues, the third integral value Inte3 is still smaller than the third default value, so the peak value adjustment signal Sout is adjusted from a low level to a high level to increase the output peak value of the power supply. After the output peak value of the power supply is increased, it can be seen that the output current Iout has already returned to a high level from the section of 0.05S~0.06S. It should be noted that the present disclosure is not limited to the parameters shown in Figures 2 and 3, which merely exemplify one of the implementation methods of the present disclosure in order to facilitate understanding of the technology of the present disclosure, and the scope of the claims of the present disclosure is based on the scope of the claims of the invention. Modifications and modifications made to the embodiments of the present disclosure by those skilled in the art without departing from the spirit of the present disclosure still fall within the scope of the claims of the present disclosure.

[0033] 4 shows a schematic process diagram of an adjustment control method 400 according to an embodiment of the present disclosure. To facilitate understanding of the adjustment control method 400, a detailed process of the adjustment control method 400 will be described below with reference to FIG. 1B and FIG.

[0034] In step 410, the first integral value in the first period of the output current is compared with a first default value, and a first comparison result is generated if the first integral value is equal to or greater than the first default value. For example, the first comparison circuit 150 determines whether the integral value of the output current in the first period (e.g., 10 ms) is equal to or greater than the first default value. If the integral value of the output current is equal to or greater than the first default value, the first comparison circuit 150 generates the first comparison result.

[0035] In step 420, the second integral value in the second period of the output current is compared with the second default value, and a second comparison result is generated if the second integral value is equal to or greater than the second default value. For example, the second comparison circuit 160 determines whether the integral value of the output current in the second period (e.g., 500 ms) is equal to or greater than the second default value. If the integral value of the output current is equal to or greater than the second default value, the second comparison circuit 160 generates a second comparison result. Note that the first default value and the second default value can also be set to be equal or unequal according to the actual needs of the present disclosure.

[0036] In step 430, in response to the first comparison result or the second comparison result, a drop signal is output to drop the output peak value of the output current. For example, when any of the above judgment conditions is achieved, the logic control circuit 180 receives the first comparison result or the second comparison result, and at this time, the logic control circuit 180 outputs a drop signal to drop the output peak value of the output current, thereby avoiding the internal components of the electronic device at the power supply end from being damaged and triggering a protection mechanism.

[0037] In step 440, after the default period, the third integral value in the default period of the output current is compared with the third default value, and if the third integral value is smaller than the third default value, a third comparison result is generated. For example, the third comparison circuit 170 determines whether the duration reaches 500 ms, and if the duration reaches 500 ms, the third comparison circuit 170 determines whether the integral value of the output current within 500 ms is smaller than the current default value. If the integral value of the output current is smaller than the current default value, the third comparison circuit 170 generates a third comparison result.

[0038] In step 450, the output peak value of the output current is increased by outputting an increase signal in response to the third comparison result. For example, when the above judgment condition is achieved, the logic control circuit 180 receives the third comparison result, and at this time, the logic control circuit 180 outputs an increase signal to increase the output peak value of the output current.

[0039] In one embodiment, the regulation control method 400 further includes integrating the current absolute value of the output current to generate a first integral value in a first period, a second integral value in a second period, and a third integral value in a default period. For example, the first integration circuit 130 and the second integration circuit 140 each integrate the current absolute value of the output current to generate a first integral value in a first period, a second integral value in a second period, and a third integral value in a default period.

[0040] In one embodiment, the regulation control method 400 further includes taking an absolute value for the current value of the output current to generate a current absolute value. Because the output current of the power supply may be an AC current, the absolute value circuit 110 needs to take an absolute value for the current value of the output current to generate a current absolute value for subsequent integration operations. For example, the first comparison circuit 150, the second comparison circuit 160, and the third comparison circuit 170 may be used to compare a first integral value in a first period of the current absolute value with a first default value, a second integral value in a second period of the current absolute value with a second default value, and a third integral value in a default period of the current absolute value with a third default value, respectively.

[0041] In one embodiment, the regulation control method 400 further includes generating a peak value regulation signal in response to the drop signal to reduce the output peak value of the output current, or generating a peak value regulation signal in response to the rise signal to increase the output peak value of the output current. For example, the peak value regulation circuit 190 is used by the logic control circuit 180 to receive the drop signal and generate the peak value regulation signal Sout to reduce the output peak value of the output current. Or, the peak value regulation circuit 190 is used by the logic control circuit 180 to receive the rise signal and generate the peak value regulation signal Sout to increase the output peak value of the output current.

[0042] It should be noted that the present disclosure is not limited to the process shown in Fig. 4, and merely illustrates one of the implementation methods of the present disclosure for the purpose of making the technology of the present disclosure easier to understand, and the scope of the claims of the present disclosure is based on the scope of the claims of the invention. Modifications and modifications made to the embodiments of the present disclosure by those skilled in the art without departing from the spirit of the present disclosure still belong to the scope of the claims of the present disclosure.

[0043] FIG. 5 shows a schematic diagram of the process of the regulation control method 500 according to an embodiment of the present disclosure. For easy understanding of the regulation control method 500, please refer to FIG. 1B and FIG. 5 together. In step 501, the output peak value is preset to be high, for example, the output peak value is preset to be 5V. In step 502, the absolute value circuit 110 takes the absolute value of the output current to generate a current absolute value. In step 503, it is determined whether the output peak value is high. If the output peak value is high, the steps on the right side of the figure are executed.

[0044] In step 504, a first period integration is performed on the current absolute value to obtain a first integral value. In step 505, the first comparison circuit 150 determines whether the first integral value is equal to or greater than a first default value. If the first integral value is equal to or greater than the first default value, step 506 is performed to lower the output peak value and adjust the parameters in the regulation control method 500 (e.g., the first integral value, the second integral value, the first count value, and the second count value) to 0, and then the process returns to step 502. If the first integral value is not greater than the first default value, step 507 is performed to add 1 to the first count value.

[0045] In step 508, it is determined whether the first count value has reached 1000. If the first count value has not reached 1000, the process returns to step 502. If the first count value has reached 1000, step 509 is executed to adjust and control the first integral value and the first count value to 0, and then the process returns to step 502.

[0046] Also, in step 510, a second period integral is performed on the current absolute value to obtain a second integral value. In step 511, the second comparison circuit 160 judges whether the second integral value is equal to or greater than the second default value. If the second integral value is equal to or greater than the second default value, step 506 is performed to lower the output peak value, and parameters in the regulation control method 500 (e.g., the first integral value, the second integral value, the first count value, and the second count value) are regulated to 0, and then the process returns to step 502. If the second integral value is not greater than the second default value, step 512 is performed to add 1 to the second count value.

[0047] In step 513, it is determined whether the second count value has reached 50000. If the second count value has not reached 50000, the process returns to step 502. If the second count value has reached 50000, step 514 is executed to adjust and control the second integral value and the second count value to 0, and then the process returns to step 502.

[0048] See step 503. If it is determined that the output peak value is not high, the steps on the left side of the figure are executed. In step 515, a default periodic integration is executed on the current absolute value to obtain a third integral value. In step 516, it is determined whether the third count value reaches 50000. If the third count value does not reach 50000, step 517 is executed to add 1 to the third count value, and then the execution returns to step 502. If the third count value reaches 50000, step 518 is executed, and the third comparison circuit 170 determines whether the third integral value is less than a third default value. If the third integral value is less than the third default value, step 520 is executed to increase the output peak value, and the parameters in the regulation control method 500 (e.g., the third integral value and the third count value) are regulated to 0, and then the execution returns to step 502. If the third integral value is not less than the third default value, step 519 is executed to regulated the third integral value and the third count value to 0, and then the execution returns to step 502. It should be noted that the present disclosure is not limited to the process shown in Fig. 5, which merely exemplifies one of the implementation methods of the present disclosure in order to facilitate understanding of the technology of the present disclosure, and the scope of the claims of the present disclosure is based on the scope of the claims of the invention. Modifications and modifications made to the embodiments of the present disclosure by those skilled in the art without departing from the spirit of the present disclosure still belong to the scope of the claims of the present disclosure.
