The normal power of a general processor is greatly different from the power in the turbo mode and can reach several times, the power selection of a power adapter matched with a computer needs to consider the economy and the portability, the power adapter is designed according to the maximum power requirements of all hardware of the computer to be overlarge and high in price, and a slightly low-power supply is generally selected in a balanced mode, so that the power requirement in the turbo mode cannot be completely met. Therefore, the power of the computer needs to be adjusted in the turbo mode to be less than the maximum output power of the power adapter, so that the power adapter with lower power can be used in cooperation with the computer.

The embodiment of the invention provides a power adjusting method which is mainly applied to an Rui frequent acceleration mode of electronic equipment in a full-load working state. The conventional central processing unit of an electronic device, such as an intel processor, defines PL (power limit level), i.e. defines PL of 4 levels, which respectively correspond to different operable time, PL1 is the maximum power limit of continuous and stable operation, PL 2-PL 4 are the maximum power limits of instantaneous operation, PL3 and PL4 are short time, which generally will not cause over-power protection of the power adapter, and therefore the over-power protection of the power adapter is mainly the instantaneous power of PL2, which can last for several seconds and far exceeds the delay time of the over-power protection of the power adapter.
Therefore, when the electronic device is fully loaded, the CPU will switch to turbo mode to boost the CPU power based on PL2 value, thereby increasing the performance of the processor. However, since PL2 is usually set to be higher, which causes the boosted cpu power to be higher than the power over-protection point of the power adapter, the boosted cpu power needs to be adjusted again to match the output power of the power adapter, so as to prevent the power adapter from being damaged. Therefore, an embodiment of the present application provides a power adjustment method, as shown in fig. 1: the method comprises the following steps:
step S101, acquiring a first output power limit value of a power adapter;
in this step, the embedded controller may be specifically used to detect a power adapter connected to the electronic device, so as to obtain the first output power limit value.
Step S102, when the electronic equipment is in a full-load working state, acquiring first power of the electronic equipment in a Rui-frequency acceleration mode;
in the specific implementation process of this step, the full-load state refers to that the peripheral interfaces of the electronic device are fully inserted, or more than half of the peripheral interfaces are fully inserted, and a complex program, such as a 3D game program, a CAD software program, and the like, is run, and at this time, the electronic device can be considered to be in the full-load state.
In this embodiment, when the electronic device is in a full-load state, the input current of the electronic device may be obtained based on the current detection resistance detection; processing is then performed with a first amplifier based on the input current to obtain the first power.
Step S103, comparing the first power with the first output power limit value;
step S104, under the condition that the first power is determined to be larger than or equal to the first output power limit value, adjusting the first power to a second power, and adjusting the initial short-time Rui frequency power limit value to a target short-time Rui frequency power limit value;
step S105, adjusting the second power of the electronic equipment based on the target short-term Rui-frequency power limit value to obtain a third power.
In this embodiment, when the first power of the electronic device in the fully loaded state is greater than the maximum output power of the power adapter, that is, greater than the first output power limit value, the power limit value is adjusted to prevent the power from being too high and still greater than the first output power limit value when the electronic device is restored to the turbo operating mode again, and the power is protected again, thereby performing power adjustment again.
Another embodiment of the present invention provides a power adjustment method, including the steps of:
in step S201, a first output power limit value of the power adapter is obtained.
Step S202, obtaining the input current of the electronic equipment based on the current detection resistance detection; the first power is obtained based on the input current.
Step S203, comparing the first power with the first output power limit value;
step S204, under the condition that the first power is determined to be larger than or equal to the first output power limit value, adjusting the first power to a second power;
step S205, adjusting the initial short-term Rui frequency power limit value in a step-by-step adjustment manner based on a preset power value to obtain the target short-term Rui frequency limit value;
in this step, the power reduction value can be determined according to actual needs, and then the short-term frequency power limit value PL2 is adjusted based on the fixed power reduction value, for example, the power reduction value is set to 20W, and when each pair of PL2 is adjusted, the power reduction value is reduced by 20W.
Step S206, adjusting the second power of the electronic device based on the target short-term Rui-frequency power limit value to obtain a third power.
Step S207, comparing the third power with the first output power limit value, and if it is determined that the third power is greater than or equal to the first output power limit value, repeatedly executing step S205 until the third power is less than the first output power.
That is, in this embodiment, when the system device is fully loaded and runs the reloading program, the CPU frequency-accelerates the turbo boost until the total system power exceeds the power protection point of the power adapter, so that the CPU will send a down-converted signal to down-convert the CPU, and at the same time the embedded controller EC will modify the PL2 value of the CPU of the processor to lower the PL2 value by one step, and specifically, the power value corresponding to one step can be defined according to the actual requirement, and then the system power down-conversion is released, and the CPU resumes the normal frequency operation, at this time, because the system is still in the full-loaded state, the CPU will restart the turbo boost, because the power limit value of the turbo boost has been adjusted and reduced, therefore, if the power reached by the processor frequency-accelerated based on the adjusted PL2 is still higher than the maximum output power of the power adapter, the CPU will first down-convert the turbo boost, then continue to lower the PL2 by one step, and so on this, until the PL2 is adjusted to the power protection point no longer triggered, this PL2 is then maintained in operation and no downconversion of the system occurs.
Specifically, the circuit shown in fig. 2 may be used to adjust the power in this embodiment. In this embodiment, a current detection resistor Rsense is connected in series between the power adapter and the system of the electronic device, and the total input current of the system is detected by using the current detection resistor Rsense. The current detection resistor sends the detected current to an error amplifier U1, the voltage containing the current signal is amplified through the error amplifier U1 to obtain Vc, namely first power, and the Vc is sent to a second comparator U2. On the other hand, the embedded controller EC detects the maximum output power inserted into the power adapter through the power adapter ID, i.e., the adaptor ID, thereby setting the maximum power protection point VREF1, i.e., setting the first output power limit value VREF1, and sending the first output power limit value VREF1 to the second comparator U2. The comparator U2 compares Vc with VREF1, if Vc is greater than VREF1, the comparator U2 outputs a high-level Alert signal to the EC, the EC sends a down-conversion signal with a short signal to the CPU, so that the CPU completes the down-conversion operation to reduce the first power to the second power, the EC modifies the PL2 value of the CPU of the processor to reduce the PL2 value to one step, and when the CPU starts the turbo boost again because the system is still in a full-load state, the CPU performs the turbo-acceleration based on the adjusted PL2, namely, adjusts the second power based on the PL2 and boosts the second power to the third power. Meanwhile, the current detection resistor Rsense can continuously detect the input current of the system and send the input current to the error amplifier U1, then the error amplifier can obtain the current third power and send the current third power to the comparator U2, if the comparator U2 determines that the third power is still larger than the first output power limit value VREF1, the EC can send a down-conversion signal throttle signal to the CPU again, so that the CPU completes down-conversion to adjust the third power, and the EC can modify the PL2 value of the processor CPU again and reduce the PL2 value by one step. This is repeated until the CPU starts turbo boost, adjusting based on the modified PL2 value that the resulting power is no longer greater than VREF 1.
Another embodiment of the present invention provides a power adjustment method, including the steps of:
in step S301, a first output power limit value of the power adapter is obtained.
Step S302, when the electronic equipment is in a full-load working state, the input current of the electronic equipment is obtained based on the current detection resistance detection; a first power of the electronic device in a turbo mode is obtained based on the input current.
Step S303, comparing the first power with the first output power limit value;
step S304, under the condition that the first power is determined to be larger than or equal to the first output power limit value, adjusting the first power to a second power;
step S305, determining a power difference value based on the first power and the first output power limit value; and adjusting the initial short-term Rui frequency power limit value based on the power difference value to obtain a target short-term Rui frequency power limit value.
In this embodiment, by determining the difference between the first power and the first output power limit, the initial short-time Rui-frequency power limit can be directly adjusted to the target short-time Rui-frequency power limit according to the difference, and the power after the turbo boost is started in a full-load state of the electronic device can be lower than the first output power limit of the power adapter only by adjusting once without adjusting step by step.
Specifically, the circuit shown in fig. 3 may be used to adjust the power in this embodiment. In this embodiment, a current detection resistor Rsense is connected in series between the power adapter and the system of the electronic device, and the total input current of the system is detected by using the current detection resistor Rsense. The current detection resistor sends the detected current to an error amplifier U1, the voltage containing the current signal is amplified through the error amplifier U1 to obtain Vc, namely first power, and the Vc is sent to a second comparator U2. On the other hand, the embedded controller EC detects the maximum output power inserted into the power adapter through the power adapter ID, i.e., the adaptor ID, to set a maximum power protection point VREF1, i.e., to obtain a first output power limit value VREF1, and sends the first output power limit value VREF1 to the second comparator U2. Comparator U2 compares Vc with VREF1, if Vc is greater than VREF1, comparator U2 is reversed, an Alert signal is sent to EC, EC sends a down-converted signal threttle signal to pull CPU to fundamental frequency, even if the frequency of CPU is controlled to be reduced to the lowest frequency, synchronously, first error amplifier U1 sends first power to subtracter U3, EC sends a detected first output power limit value VREF1 to subtracter U3, power difference can be obtained through subtracter U3, and then power difference is sent to EC, so that EC can correct the amplitude of PL2 value according to the power difference, and it is ensured that the best adaptive value can be obtained by correcting PL2 value once.
Another embodiment of the present invention provides a power adjustment method, including the steps of:
step S401, acquiring a first output power limit value of the power adapter;
in this step, the embedded controller may be specifically used to detect a power adapter connected to the electronic device, so as to obtain the first output power limit value.
Step S402, when the electronic device is in a full-load working state, acquiring first power of the electronic device in a Rui-frequency acceleration mode;
in this step, the input current of the electronic device may be obtained specifically based on the current detection resistance detection; the first power is then obtained based on the input current.
Step S403, comparing the first power with the first output power limit value;
step S404, under the condition that the first power is determined to be greater than or equal to the first output power limit value, adjusting the first power to a second power, and adjusting the initial short-time Rui-Fi power limit value to a target short-time Rui-Fi power limit value;
in this step, when the initial short-term Rui-Fi limited value is adjusted to the target short-term Rui-Fi limited value, the initial short-term Rui-Fi limited value can be adjusted by a step-by-step adjustment method based on a preset power value, so as to obtain the target short-term Rui-Fi limited value until the third power is smaller than the first output power limited value.
Or, determining a power difference value based on the first power and the first output power limit value; and adjusting the initial short-term Rui frequency power limit value based on the power difference value to obtain a target short-term Rui frequency power limit value.
Step S405, adjusting the second power of the electronic device based on the target short-term Rui-frequency power limit value to obtain a third power.
Step S406, detecting the working state of the electronic equipment in real time;
step S407, when it is determined that the electronic device is switched from a full-load state to a non-full-load state, comparing the third power with a second output power limit value;
in this step, the second output power limit is determined based on the first output power limit.
Step S408, when it is determined that the third power is smaller than the second output power limit value, adjusting the third power based on the initial short-term Rui-frequency power limit value to obtain a fourth power.
In this implementation, when the system is in a fully loaded state, the CPU adjusts the initial PL2 to the target PL2 after starting the turbo boost to meet the adapter output power requirement. However, when the system is switched from the full state to the non-full state, for example, the system stops running a complex program such as a 3D game, CAD software, or a device accessed by a peripheral interface is removed, the power of the whole system is reduced, so that the PL2 of the CPU can be restored to the initial value, thereby increasing the reserved turbo boot space of the CPU. The PL2 of the CPU can be restored to the initial value without restarting, making the restoration of PL2 more convenient and faster.
Specifically, the circuit shown in fig. 4 may be used to adjust the power in this embodiment. In this embodiment, a current detection resistor Rsense is connected in series between the power adapter and the system of the electronic device, and the total input current of the system is detected by using the current detection resistor Rsense. The current detection resistor sends the detected current to an error amplifier U1, the voltage containing the current signal is amplified through the error amplifier U1 to obtain Vc, namely first power, and the Vc is sent to a second comparator U2. On the other hand, the embedded controller EC detects the maximum output power inserted into the power adapter through the power adapter ID, i.e., the adaptor ID, thereby setting the maximum power protection point VREF1, i.e., setting the first output power limit value VREF1, and sending the first output power limit value VREF1 to the second comparator U2. The comparator U2 compares Vc with VREF1, if Vc is greater than VREF1, the comparator U2 outputs a high-level Alert signal to the EC, the EC sends a down-conversion signal with a short signal to the CPU, so that the CPU completes the down-conversion operation to reduce the first power to the second power, the EC modifies the PL2 value of the CPU of the processor to reduce the PL2 value to one step, and when the CPU starts the turbo boost again because the system is still in a full-load state, the CPU performs the turbo-acceleration based on the adjusted PL2, namely, adjusts the second power based on the PL2 and boosts the second power to the third power. Meanwhile, the current detection resistor Rsense can continuously detect the input current of the system and send the input current to the error amplifier U1, then the error amplifier can obtain the current third power and send the current third power to the comparator U2, if the comparator U2 determines that the third power is still larger than the first output power limit value VREF1, the EC can send a down-conversion signal throttle signal to the CPU again, so that the CPU completes down-conversion to adjust the third power, and the EC can modify the PL2 value of the processor CPU again and reduce the PL2 value by one step. This is repeated until the CPU starts turbo boost, adjusting based on the modified PL2 value that the resulting power is no longer greater than VREF 1.
When the electronic device is switched from a fully loaded state to a non-fully loaded state, for example, when the external device is removed, the error amplifier U1 sends the system power value Vc detected in real time to a filter, the filter obtains an average power value Vcm according to the real-time power value Vc, and then sends the Vcm to the comparator U3, and the embedded controller outputs VREF1 to the comparator U3, specifically, outputs VREF2 to the comparator U3 through a voltage dividing resistor, wherein the specific size of VREF2 may be set according to actual needs, for example, VREF1 × 0.6 is set as VREF 2. Comparator U3 compares Vcm to VREF 2. When Vcm is less than VREF2, U3 outputs a signal to EC, which controls the CPU to restore PL2 to the initial set value, i.e., to the initial short-term power limit.
In this embodiment, when the system initially maintains the default PL2 setting value, the system is fully operating, the system current may touch the power point set by VREF1, at this time, the U2 comparator outputs a high level, EC decreases by one step for GPU PL2, generally, the system peak current may decrease, if the VREF1 setting point is not triggered after decreasing, this PL2 is maintained to operate, if the system peak current is still higher than the VREF1 setting point, the first-order PL2 continues to decrease until the VREF1 setting point is not triggered, if the user removes the peripheral or changes the operating program during use, the system average power may decrease greatly, so that the system average power Vcm is lower than VREF2, U3 may output a signal to notify EC, and EC may control the CPU to restore PL2 to the PL2 initial setting value. Thus, automatic restoration of PL2 is achieved, eliminating the need to restore PL2 by rebooting.
