Detailed Description
The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.
As shown in fig. 1, an embodiment of the present invention provides a power module control method, including the following implementation steps: a power module control method comprises the following implementation steps: the baseboard management controller BMC collects the running state information of the main power supply module and the running state information of the secondary power supply module; acquiring system energy consumption from the power module operation state information according to the main power module operation state information; outputting a power supply module control signal according to the system energy consumption and the conversion efficiency-load curve of the main power supply module and the slave power supply module; the conversion efficiency-load curve is obtained by inquiring a technical manual or testing; and the master power supply module and the slave power supply module are turned on or turned off according to the power supply module control signal.
It should be noted that the power module operation state information includes information such as input/output voltage, input/output current, and energy consumption of the power module.
Generally, the conversion efficiency of the power module has a parabolic relationship with the load, and a typical power module conversion efficiency-load curve is shown in fig. 2. It can be seen that the power module conversion efficiency peaks when the power module is around 50% load. The conversion efficiency-load curves of different power supply modules are different, and can be obtained through a product manual provided by a power supply module provider, or the output voltage U can be tested by loading different loadsOutput ofAnd an output current IOutput ofAnd an input voltage UInput deviceAnd an input current IInput deviceAnd obtaining the result.
Conversion efficiency of UOutput of*IOutput of/(UInput device*IInput device);
Further, a conversion efficiency-load curve can be obtained.
The energy consumption of the system can be obtained by the following formula:
the system energy consumption is the energy consumption of the main power supply module and the energy consumption of the slave power supply module.
When some server electric equipment is idle, the power consumption is usually only 20% or lower of rated power, two power supplies work simultaneously, a single power supply module bears 10% of load, and compared with a conversion efficiency-load curve, when the electric equipment is idle, most of the two power supply modules work in a low-efficiency state.
In the above embodiment, the power module is dynamically turned on and off according to the energy consumption condition of the electric equipment and the conversion efficiency-load curve of the power module, so that the conversion efficiency of the power module is improved, and the energy consumption of the system is saved.
Optionally, as shown in fig. 3, when the system consumes more than or equal to the rated power of the main power supply module, outputting a start control signal from the power supply module;
when the system energy consumption is less than the rated power of the main power supply module, comparing the power supply conversion efficiency when the main power supply module works alone with the power supply conversion efficiency when the main power supply module and the slave power supply module work simultaneously, and when the power supply conversion efficiency when the main power supply module works alone is less than or equal to the power supply conversion efficiency when the main power supply module and the slave power supply module work simultaneously, outputting a slave power supply module starting control signal; otherwise, the slave power module closing control signal is output.
It should be noted that, the conversion efficiency of the main power module working alone can be obtained by using the system energy consumption as the input load of the power module and querying the conversion efficiency-load curve of the power module. When the power supply module works simultaneously, the master power supply module and the slave power supply module respectively bear half of the load consumed by the current system, half of the energy consumed by the system can be used as the input load of the power supply module, and the conversion efficiency-load curve of the power supply module is inquired to obtain the conversion efficiency when the power supply module works simultaneously.
In the above embodiment, on the premise that the main power module works alone to meet the power requirement of the system, the conversion efficiency of the main power module working alone is compared with the conversion efficiency of the main power module and the auxiliary power module working simultaneously, so that the highest conversion efficiency is used as the judgment standard of the switch of the auxiliary power module, thereby improving the conversion efficiency of the power module.
Optionally, the outputting a power module control signal according to the system power consumption and a conversion efficiency-load curve of the master power module and the slave power module includes: when the system energy consumption is greater than or equal to 90% of the rated power of the main power supply module, outputting a starting control signal of the auxiliary power supply module; when the system energy consumption is less than 90% of the rated power of the main power supply module, comparing the power supply conversion efficiency when the main power supply module works alone with the power supply conversion efficiency when the main power supply module and the slave power supply module work simultaneously, and outputting a slave power supply module starting control signal when the power supply conversion efficiency when the main power supply module works alone is less than or equal to the power supply conversion efficiency when the main power supply module and the slave power supply module work simultaneously; otherwise, the slave power module closing control signal is output.
In the above embodiment, the system energy consumption is compared with 90% of the rated power of the main power module to determine that the corresponding processing is performed, so that the safety of power supply of the system power supply can be further improved, sudden change of the system energy consumption and insufficient power supply of the main power module are avoided, the system stability is influenced, and the stability of the system power supply is improved.
It will be appreciated that the skilled person may set ratios other than 90%, such as 70%, 60% etc., depending on the severity of the power consumption of the system and the need for safety of the power supply.
Optionally, the power module control signal is a PMBUS control signal, and the master power module and the slave power module support the PMBUS.
