The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.
The first embodiment,
As shown in the figure, a real-time energy consumption management and control technology for a multiphase parallel operation mode power supply includes the following steps:
step one, detecting load power;
step two, establishing a multi-phase parallel power supply unit meeting the power utilization requirement according to the load power;
step three, detecting the load power consumption condition in real time through a detection circuit;
and step four, calculating the number of phases required to be connected in parallel by the multi-phase parallel power supply unit according to the load power consumption.
The invention realizes primary energy consumption management and control of the power supply unit, can widen the high conversion efficiency load interval of the power supply unit, and ensures that the power supply unit has higher conversion efficiency in the effective load working interval, thereby having small energy consumption, high energy utilization rate, energy conservation and environmental protection.
Example II,
Step one, detecting load power;
step two, establishing a multi-phase parallel power supply unit meeting the power utilization requirement according to the load power;
step three, detecting the load power consumption condition in real time through a detection circuit;
and step four, calculating the number of phases required to be connected in parallel by the multi-phase parallel power supply unit according to the load power consumption.
And step five, opening or closing the appointed phase through the control circuit, so that the number of actually working phases is consistent with the required number of phases.
In the second embodiment, the number of phases in the proper actual situation can be further selected by adjusting the designated phases.
In the above two embodiments, the electricity demand refers to the electricity consumption required in the current working environment. The specified phase refers to the amount of electricity used between the calculated number of phases and the actual number of phases.
Example III,
The technology for realizing the first embodiment and the second embodiment comprises a structure, a detection module, a calculation module and a control module, wherein the detection module is used for detecting load power, the calculation module is used for calculating the number of phases required to be connected in parallel by the multi-phase parallel power supply unit, and the control module is used for controlling a circuit to open or close a specified phase.
The invention realizes the primary energy consumption management and control of the power supply unit, can widen the high-conversion-efficiency load interval of the power supply unit, and ensures that the power supply unit has higher conversion efficiency in the effective load working interval. The power conversion efficiency in the low load interval in the load power is improved by more than 5%. The low load interval is less than 30% of the load power.
The specific embodiment of the method of the invention is as follows:
as shown in fig. 1, the left part is 4 parallel working mode power supplies, each phase has an output capacity of 1000W and a maximum output capacity of 4000W, and the right part represents an electricity utilization unit, and the power is variable.
Fig. 2 shows a conversion efficiency curve of the number of operation phases, and it can be seen from the curve that in the low load region (0A ~ 100A), the smaller the number of operation phases, the higher the conversion efficiency, but the smaller the number of operation phases, the lower the overall power supply capacity.
In order to give consideration to both power supply capacity and conversion efficiency, the invention is provided, the actually required working phase number is calculated according to the real-time detection load power value, and the multiphase parallel working mode power supply is controlled. As shown in fig. 1 as an example, when the load power is detected to be 1500W, the number of operating phases of the power supply is set to 2, and the conversion efficiency curve of the power supply is changed from the curve indicated by the 4-way in fig. 2 to the curve indicated by the 2-way, i.e., in the interval range of 0-150A, the fourth curve from the left side is changed to the second curve from the left side. The conversion efficiency is improved by about 5 percent. When the number of working phases is adjustable from 1 phase to 4 phases, the overall conversion efficiency of the power supply is shown by the curve indicated on the left side of fig. 3.
As shown in FIG. 3, it can be seen that the present invention can effectively improve the conversion efficiency of the output interval of the exemplary power supplies 0A-150A.
