[0040] Embodiment 1

[0041] Figure 1A is a schematic structural diagram of a voltage regulation system provided in Embodiment 1 of the present invention. As Figure 1A shown, the voltage regulation system includes a management module 100, a control module 200, and an execution module 300; the control module 200 is respectively connected to the management module 100 and the execution module 300; the management module 100 is used to store the current thresholds of each current interval and the voltage values respectively corresponding to each current interval.

[0042] Specifically, first, the output current of the VRM is divided into two intervals, namely the voltage regulation current interval and the steady-state current interval; among them, the voltage regulation current interval, that is, the current interval with insufficient transient response. When the output current of the VRM is in the voltage regulation current interval, the output voltage of the VRM needs to be adjusted; the steady-state current interval, that is, the current interval with sufficient transient response, is also the current interval in the normal working state. When the output current is in the steady-state current interval, the output voltage of the VRM does not need to be adjusted, and the current output voltage of the VRM can be maintained. Therefore, the voltage value of the steady-state current interval can be set to a null value, that is, the voltage regulation operation is not performed.

[0043] Secondly, different sub-intervals can be further divided within the regulated current range. Different regulated current sub-intervals correspond to different voltage values. That is, when the output current of the VRM is in different regulated current sub-intervals, the output voltage of the VMR needs to be adjusted to different voltage values. The management module 100 records the current thresholds (including upper and lower threshold values) of each of the above current ranges (including the steady-state current range and each regulated voltage sub-interval), and the voltage values corresponding to each current range. Optionally, in the embodiments of the present invention, neither the number of current ranges nor the current thresholds of the current ranges are specifically limited.

[0044] The control module 200 is configured to determine a matching target current range according to the output current of the voltage regulation module, and obtain the target voltage value corresponding to the target current range. The execution module 300 is configured to adjust the output voltage of the voltage regulation module according to the target voltage value. When the control module 200 obtains the current output current, it determines the target current range where the output current is located and the target voltage value corresponding to the target current range according to the current value of the output current. The execution module 300 specifically adjusts the output voltage of the VRM through an internal voltage regulation circuit.

[0045] The voltage regulation system in the embodiments of the present invention monitors the output current of the VRM and adjusts the output voltage of the VRM in real time through a pre-adjustment method, thereby solving the problem that when the load current suddenly jumps under different load currents and different operating modes of the VRM, the VRM system reacts too slowly and the load voltage drops too much.

[0046] As Figure 1B shown, optionally, in the embodiments of the present invention, the management module 100 includes a plurality of first registers 101; the control module 200 includes a data selector 201 and an identification register 202; the data selector 201 is respectively connected to the management module 100 and the identification register 202; the control module 200 is specifically configured to establish a transmission channel between the target first register 101 corresponding to the target current range and the identification register 202 through the data selector 201, and transmit the target voltage value in the target first register 101 to the identification register 202; the execution module 300 is specifically configured to adjust the output voltage of the voltage regulation module according to the target voltage value stored in the identification register 202.

[0047] Specifically, the registers in the management module 100 (i.e., the first registers 101) are in one-to-one correspondence with current ranges. Each first register 101 stores the upper threshold and lower threshold of the current range, as well as the corresponding voltage value. The multiplexer 201 in the control module 200 is connected to each first register 101 through different break switches. After the control module 200 determines the target current range to be matched according to the output current of the voltage regulation module, a transmission channel is established between the target first register (i.e., the first register 101 corresponding to the target current range) and the multiplexer 201 according to the target first register.

[0048] The target voltage value in the target first register 101 can enter the identification register 202 through the multiplexer 201 via the above-mentioned transmission channel. Among them, the identification register 202 is used to store the voltage value to be adjusted currently. Thereafter, the execution module 300 adjusts the output voltage of the VRM according to the voltage value to be adjusted in the identification register 202 so that the output voltage of the VRM reaches the target voltage value. Thus, through the transmission channel constructed by the multiplexer 201, the effective transmission of the target voltage value is realized, and the adjustment speed of the output voltage of the VRM is improved. In addition, the control module 200 can also configure the number of current ranges in the management module 100 and the current thresholds of each current range according to the obtained configuration parameters to meet the requirements of different main control chips.

[0049] Optionally, in the embodiment of the present invention, the management module 100 is further configured to, if it detects that there is an overlapping range between the first current range and the second current range, merge the first current range and the second current range into a third current range, and use the larger one of the first voltage value corresponding to the first current range and the second voltage value corresponding to the second current range as the voltage value of the third current range.

[0050] Specifically, when the operation and maintenance personnel send configuration parameters to the management module 100, there may be a phenomenon that there is an overlapping range between current ranges. For example, the first current range is from 0.5 A to 1 A, and its corresponding voltage value is 1 V. The second current range is from 0.8 A to 1.2 A, and its corresponding voltage value is 1.2 V. At this time, the first current range and the second current range can be merged into a third current range, that is, from 0.5 A to 1.2 A, and the corresponding voltage value of the third current range is the larger one of the above two voltage values, that is, 1.2 V is used as the voltage value corresponding to the third current range. Thus, when there is an overlap in the current range, a new circuit range can be obtained through the merging method, ensuring that the adjusted output voltage meets the response of the transient current.

[0051] In the technical solution of the embodiment of the present invention, the voltage regulation system determines a matching target current range according to the output current of the voltage regulation module, obtains the target voltage value corresponding to the target current range, and then adjusts the output voltage of the voltage regulation module according to the target voltage value. Thus, the output voltage of the voltage regulation module is adjusted in real time by means of pre-adjustment, solving the problem that the load voltage drops too much when the load current suddenly jumps under different load currents and different working modes of the voltage regulation module, greatly improving the transient response effect of the voltage regulation module. At the same time, the above adjustment method is not affected by the inherent characteristics of the semiconductor and the conversion efficiency of the voltage regulation module itself. Compared with the traditional optimized feedback control circuit, the number of load capacitors of the voltage regulation module is reduced, and the hardware cost and space cost are reduced.

[0052] Embodiment 2

[0053] Figure 2A FIG. is a schematic structural diagram of a voltage regulation system provided in Embodiment 2 of the present invention. As Figure 2A shown, the voltage regulation system further includes an enable module 400; the enable module 400 is connected to the management module 100 and is configured to obtain an enable instruction and send the parsing result of the enable instruction to the management module 100; the management module 100 is configured to configure the corresponding current range as an enabled state according to the parsing result of the enable instruction.

[0054] In the initial state, each current range can be configured as a non-enabled state, which can not only avoid unstable currents in the initial startup state from causing misregulation of the output voltage, but also ensure the voltage safety during the switching and replacement of the main control chip; one or more current ranges can be configured as an enabled state through the enable module 400; in particular, a relatively large number of current ranges can be set at the same time to make the current ranges meet the requirements of various different types of main control chips. When switching or replacing the main control chip, a specific one or more current ranges can be configured as an enabled state for the current main control chip to achieve flexible configuration of the enabled state of the current range.

[0055] As Figure 2B shown, optionally, in the embodiment of the present invention, the enable module 400 includes a data distributor 401 and a plurality of second registers 402; the enable module 400 is specifically configured to establish a transmission channel between the target second register and the management module 100 through the data distributor 401 according to the enable instruction, so as to send the enable signal to the management module 100.

[0056] Specifically, the number of the second registers 402 is the same as that of the first registers, and they are in one-to-one correspondence with the current intervals. Obviously, the second registers 402 are also in one-to-one correspondence with the first registers. The data distributor 401 can obtain the enable instruction through the pins of the hardware device, or directly obtain the enable instruction issued in the form of software. When the data distributor 401 obtains the enable instruction, it obtains the current interval pointed to by the enable instruction, and obtains the target second register corresponding to the current interval, then establishes a transmission channel between the target second register and the management module 100, and sends the enable signal to the management module 100 through the above transmission channel.

[0057] Since the management module 100 is respectively connected to each second register 402 through different buses, when the management module 100 receives the enable signal sent by the target second register, it can determine the identity information of the target second register, and then configure the current interval stored in the first register corresponding to the target second register to the enabled state. Thus, through the transmission channel constructed by the data distributor 401, the effective transmission of the enable signal is realized, meeting the voltage regulation requirements of different main control chips for different current intervals, and thereby realizing the flexible configuration of the enabled state of the current intervals. In addition, the management module 100 can also set the current thresholds of each current interval and the voltage values corresponding to each current interval according to the obtained configuration instructions, so as to adjust the current thresholds and the corresponding voltage values of each current interval according to different voltage regulation requirements.

[0058] In the technical solution of the embodiment of the present invention, the enabling module, according to the enable instruction, establishes a transmission channel between the target second register and the control module through the data distributor to send the enable signal to the control module, realizing the effective transmission of the enable signal, meeting the voltage regulation requirements of different main control chips for different current intervals, and thereby realizing the flexible configuration of the enabled state of the current intervals.

[0059] Embodiment III

[0060] Figure 3A FIG. is a schematic structural diagram of a voltage regulation system provided for Embodiment III of the present invention, as Figure 3AAs shown, the voltage regulation system further includes an analysis module 500; the analysis module 500 includes a conversion unit 501, a filtering unit 502, a comparison unit 503, a voltage division unit 504, and a debouncing unit 505; the comparison unit 503 includes a plurality of comparators; the voltage division unit 504 includes a plurality of voltage division resistors; the conversion unit 501, connected to the filtering unit 502, is configured to convert the output current of the voltage regulation module into a voltage signal; the filtering unit 502, connected to the debouncing unit 505, is configured to perform filtering processing on the voltage signal; the comparison unit 503, connected to the voltage division unit 504, is configured to obtain the voltage signal and obtain a reference voltage through the voltage division unit 504, and output a voltage comparison result; the debouncing unit 505, connected to the comparison unit 503, is configured to perform debouncing processing on the voltage comparison result; the control module 200 is specifically configured to determine a matching target current range according to the voltage comparison result.

[0061] Specifically, the conversion unit 501 converts the current signal output by the VRM in real time into a voltage signal, and sends the voltage signal to the filtering unit 502; the filtering unit 502 performs noise removal processing on the above voltage signal through an internal filter; wherein, the filter in the embodiment of the present invention may be a low-pass filter, that is, it allows signals below or equal to the cut-off frequency to pass through and does not allow signals above the cut-off frequency to pass through; the filtering unit 502 transmits the voltage signal after noise removal to each comparator in the comparison unit 503.

[0062] The number of comparators in the comparison unit 503 matches the number of current ranges, that is, the number of comparators is equal to 2 times the minimum number of binary digits representing the number of current ranges; for example, when the number of current ranges is 4, obviously each current range can be represented by 2 binary digits, that is, "00", "01", "10" and "11" respectively represent a current range, but since each current range corresponds to an upper threshold and a lower threshold respectively, therefore, actually 4 binary digits are needed to represent the upper threshold and the lower threshold of each current range, that is, "00", "01", "10" and "11" of two of the binary digits respectively represent the upper thresholds of different current ranges; "00", "01", "10" and "11" of the other two binary digits respectively represent the lower thresholds of different current ranges; at this time, four comparators are needed to output the voltage comparison result, and each voltage comparison result represents one of the digits.

[0063] Such as Figure 3BAs shown, the entire current range is divided into four current ranges, that is, there are four current upper limit thresholds and four current lower limit thresholds at this time; at this time, the comparison unit 503 is composed of four comparators, namely comparator A, comparator B, comparator C, and comparator D; among them, the output results of comparator A and comparator C are the digits corresponding to the current upper limit thresholds respectively; the output results of comparator B and comparator D are the digits corresponding to the current lower limit thresholds respectively.

[0064] For example, comparator A, comparator B, comparator C, and comparator D output 1, 1, 0, and 0 respectively; it represents the current upper limit threshold corresponding to "10" and the current lower limit threshold corresponding to "10"; from this, the current range where the current output by the VRM is located, that is, the target current range, can be determined. At this time, the target voltage value corresponding to the target current range is the voltage value expected to be achieved in this adjustment.

[0065] Optionally, in the embodiment of the present invention, each voltage dividing resistor in the voltage dividing unit 504 is connected to the comparator in the comparison unit 503 in parallel. Specifically, taking the comparison unit 503 including 4 comparators as an example, as Figure 3C shown, each voltage dividing resistor is connected to each comparator in parallel; compared with the connection method in Figure 3B , different comparators in Figure 3B are connected to different numbers of voltage dividing resistors, and the reference voltages received by each comparator must be different. Therefore, Figure 3B the series connection method of the comparator and the voltage dividing unit 504 in

[0066] makes the corresponding current thresholds definitely have no overlapping parts in the interval; Figure 3C while in Figure 3C , different comparators are connected to the same number of voltage dividing resistors. When the resistance values of two voltage dividing resistors are the same, the reference voltages obtained by the two comparators are also the same at this time. Since the output voltage signal of the above VRM is also the same, for these two comparators, the same result will be obtained, that is, there may be overlapping parts in the respective corresponding current ranges; this is more flexible for configuring the current range because even if there is an overlapping phenomenon when configuring the current range, a matching current value can still be found. In addition,

[0067] the parallel connection method in Figure 3C makes more adjustable resistors be connected in the parsing module 500, which is more convenient for flexibly adjusting the reference voltages of each comparator.

[0067] At the same time, the comparator in the embodiment of the present invention can have a hysteresis comparison function, that is, among the current thresholds of each current range, the upward crossing threshold is higher than the downward crossing threshold, which is used to prevent the current from frequently crossing back and forth within the interval, resulting in unstable voltage; the debounce time of the debounce unit 505 can be set as needed, which is used to ensure that the output current of the VRM stably enters the current range before performing the next voltage regulation operation.

[0068] In the technical solution of the embodiment of the present invention, the parsing module 500 converts the output current of the voltage regulation module into a voltage signal and transmits it to a plurality of comparators together with a reference voltage, so as to determine the target current range based on the voltage comparison results of the comparators. This not only realizes the accurate acquisition of the target current range and improves the accuracy of the output current partitioning of the voltage regulation module, but also ensures the rapid acquisition of the target current range, and further realizes the real-time regulation of the output voltage of the voltage regulation module.

[0069] Application scenario 1

[0070] Figure 3D It is a schematic diagram of the voltage regulation result of the voltage regulation system provided for Application Scenario 1 of the present invention, as Figure 3D shown:

[0071] At the initial moment when the voltage regulation module is running, that is, in the time period from 0 second to 5 seconds, the output current is small, and it can be determined that it is in the current range of 5 milliamperes (i.e., the first lower threshold) to 15 milliamperes (i.e., the first upper threshold). At this time, it is not necessary to adjust the output voltage of the VRM, and the current output voltage can be maintained; at the 5th second, the VRM has a large transient current, which causes the system to crash probabilistically; in the traditional technical solution, to solve the above problems, usually the hardware structure of the VRM is improved, and the entire power distribution network needs to be optimized.

[0072] In the embodiment of the present invention, at the 5th second, it has been determined that the output current is in the current range of 115 milliamperes (i.e., the second lower threshold) to 135 milliamperes (i.e., the second upper threshold). At this time, according to the voltage value corresponding to this current range, the output voltage of the VRM is adjusted. Thus, by temporarily dynamically adjusting the output voltage, the insufficient current transient response at the 5th second is compensated, and the problem of the crash of the Power Management Integrated Circuits (PMIC) is solved; among them, the VRM is a functional component in the PMIC; this avoids the cumbersome operation of modifying the power distribution network of the PMIC again, and reduces the capacitance cost and space cost increased by improving the power distribution network of the power management chip.

Thus, the output voltage of the voltage regulation module is adjusted in real time by means of pre-adjustment, thereby solving the problem that when the load current suddenly jumps under different load currents and different working modes of the voltage regulation module, the load voltage drops too much, greatly improving the transient response effect of the voltage regulation module. At the same time, the above adjustment method is not affected by the inherent characteristics of the semiconductor and the conversion efficiency of the voltage regulation module itself. Compared with the traditional optimized feedback control circuit, the number of load capacitors of the voltage regulation module is reduced, and the hardware cost and space cost are reduced.

Thus, the output voltage of the voltage regulation module is adjusted in real time by means of pre-adjustment, thereby solving the problem that the load voltage drops too much when the load current suddenly jumps under different load currents and different working modes of the voltage regulation module, greatly improving the transient response effect of the voltage regulation module. At the same time, the above adjustment method is not affected by the inherent characteristics of semiconductors and the conversion efficiency of the voltage regulation module itself.
