Description
Technical Field
The field relates to the field of computers, and more particularly to a server power consumption conversion system and a server.
Background
The monitoring of power consumption on a high-power server is the most common way at present, and the purpose of the monitoring is to protect a PSU (power supply unit) from over-current and over-temperature protection and further turn off the PSU due to power consumption exceeding the load of the PSU provided by other high-power chips such as a CPU or a GPU. The shut down of the PSU causes the server to stall, resulting in loss of users and businesses. Therefore, the system power consumption monitoring can accurately monitor power factors such as voltage, current and the like, and can inform the CPU to reduce the consumed power in a digital signal mode before overcurrent protection occurs so as to prevent the whole system from being shut down.
Although the power consumption state of the system can be accurately obtained by the way of the digital signal Pmbus (open standard power management protocol), the CPU system power consumption can also be reported by the Pmbus, but the processing reaction time is prolonged due to polling of the chip, which causes the uncoordinated control of the CPU and the power consumption due to too long time, and the efficiency and the protection are also greatly discounted.

And the input end of the first transconductance amplifier is connected to a preset pin of the power supply.
Presetting a pin as I set on PSUshareThe proportional relationship between the voltage output by the pin and the voltage converted according to the value of the current output by the PSU is substantially as shown in table 1 below, for example, the maximum output current of the PSU is 100 amperes, the current output current of the PSU is 50 amperes, the output percentage is 50%, and it can be seen from the table that the voltage corresponding to 50% is 4 volts. By transforming the characteristic I of the amplifier gm V, I can be reducedshareThe voltage output by the pin is converted into a current signal with the microampere level. The process of this conversion takes a short time, typically 1us to 10 us.
TABLE 1 Current to Voltage ratio
| Output current ratio | Output voltage (V) | Error in voltage |
| 40％ | 3.2000 | 5％ |
| 50％ | 4.0000 | 5％ |
| 60％ | 4.8000 | 5％ |
| 70％ | 5.6000 | 5％ |
And the input end of the second transconductance amplifier is connected to the output end of the power supply.
The input voltage of the second transconductance amplifier is directly obtained from the system voltage 12V, and the 12V voltage can be converted into a current signal of microampere level by the characteristic I of the transconductance amplifier being gm × V. The process of this conversion takes a short time, typically 1us to 10 us.
And a voltage rectifier, wherein the first input end of the voltage rectifier is connected to the output end of the first transduction amplifier, the second input end of the voltage rectifier is connected to the output end of the second transduction amplifier, and the output end of the voltage rectifier is connected to the server CPU.
The voltage rectifier converts the input voltage into a digital signal, and transmits the digital signal to the CPU through an Intel power management communication protocol, and the voltage value or the current value in the PSU can be obtained according to the requirement in the CPU, wherein the conversion and transmission process only needs 2us-10 us. The CPU can then calculate the output power consumption of the PSU based on the obtained voltage and current values.
The first resistor is connected between the first transconductance amplifier and the first input end of the voltage rectifier, and the second resistor is connected between the second transconductance amplifier and the second input end of the voltage rectifier. The two resistors are used for converting the current output from the transconductance amplifier into voltage and then outputting the voltage to the voltage rectifier.
By the technical scheme of the invention, the response speed and the accuracy of signal transmission can be effectively improved, and the effect of power conversion can be achieved by omitting an expensive logic circuit.
In a preferred embodiment of the present invention, as shown in fig. 2, the first transconductance amplifier and the second transconductance amplifier have the same structure, including:
an active current mirror;
and the non-inverting input end of the operational amplifier is connected to the input end of the transduction amplifier through a third resistor and is grounded through a fourth resistor, the inverting input end of the operational amplifier is connected to the drain electrode of the mos tube where the input end of the active current mirror is located, and the output end of the operational amplifier is connected to the input end of the active current mirror, is grounded through a first capacitor and is grounded through a second capacitor and a fifth resistor.
In a preferred embodiment of the present invention, an active current mirror includes:
the source electrode of the first mos tube is connected to the source electrode of the second mos tube, the grid electrode of the first mos tube is connected to the grid electrode of the second mos tube, the drain electrode of the first mos tube is connected to the grid electrode of the second mos tube, the source electrode of the third mos tube is connected to the drain electrode of the first mos tube, the drain electrode of the third mos tube is grounded through a sixth resistor, the grid electrode of the third mos tube is connected to the input end of the active current mirror, and the drain electrode of the second mos tube is connected to the output end of the active current mirror.
According to the characteristics gm of the transducted amplifier, I is Iout, and V is Input. Since the current mirror circuit Iout is equal to Vgm/Rgm, Vgm is the voltage division of Input signal and Rtop and Rbot. The circuit composed of OPA (operational amplifier) and C1, C3 and R generates a zero fz ═ 1/(2 pi R1C1) and a pole fp ═ C1+ C3)/(2 pi R1C 3, which can increase the stability and bandwidth of the output signal, increase the signal bandwidth of the zero, and reduce the noise interference of the pole. For example, when the PSU output current is 100%, as shown by I in Table 1shareThe voltage was 8V. Setting Rtop to 90K Ω, Rbot to 10K Ω, and Rgm to 1K Ω, Input8V obtains a voltage of 0.8V through Rtop/Rbot voltage division. Since the voltage at the positive Input terminal of the operational amplifier is directly fed back to the Input terminal through the voltage follower output voltage, Vgm is 0.8V, and Iout is Vgm/Rgm, when the PSU output current is 100%, Iout is 0.8V/1k Ω is 800uA, and the gain gm of the transconductance amplifier is 800 uA/8V. If the first resistance is 1K Ω, Isys (Input gm 1K Ω) V is 0.8V, so if I isshareWhen the voltage is 8V, 0.8V is input to the voltage rectifier, the voltage rectifier can restore the actual current value through the conversion of an internal ADC (analog-to-digital converter) and a formula, and then the actual current value is quickly returned to the CPU through an SVID (Intel power management communication protocol), so that the CPU achieves the quick adjustment efficiency.
