Background technique

With the continuous development of electrical and electronic products, power supply products are becoming more and more abundant. From the early AC regulated power supply and DC regulated power supply to the current AC uninterruptible power supply, DC uninterruptible power supply, charging power supply, and inverter power supply, the power is as large as megawatts and as small as milliwatts. Refusing to complete the statistics, the annual output value of power supply products accounts for 6%-7% of the annual output value of the entire electronic product, which shows that the use range of power supply products is very wide. However, with the rapid development of society's informatization and intelligence, the requirements for power supply quality and power supply guarantee are also constantly increasing. From another point of view, it also shows that with the development of society's informatization and intelligence, all parts are more and more dependent on electric energy. But the earth's resources are limited. In order to ensure the sustainable growth of the economy to the greatest extent, people are always trying to find ways to save existing energy while actively seeking new energy and developing renewable energy.

Contents of the invention

The utility model is proposed after fully analyzing the working principles of various existing power supplies and summarizing the working characteristics and working habits of most of the electric loads.

It not only saves the unnecessary energy consumed by the continuous full-power operation of the power supply itself regardless of the load condition, but also prolongs the life of the power supply because it is often in a dormant state.

The technical scheme that the utility model takes is:

A cognitive power supply, including a power control unit, a power supply unit, and a power sensing unit, the power power unit is connected to the power control unit and the power sensing unit, the power sensing unit is connected to the power control unit, and the power load; the power control unit includes : The power factor correction module of the power supply, starts the power module, the processor module, and the power distribution module, accepts the information sent by the power sensing part, and controls the power part of the power supply to enter the sleep state or the active state; the power part of the power supply includes the power supply module, which provides the load Under the command of the power control part, it can enter the dormant state or be awakened into the working state; the power sensing part includes the power calculation module and the acquisition module, which can sense the change of the power load power of the power supply in real time and send the corresponding information to the The power supply control part; the power factor correction module of the power supply, which completes the power factor correction of the entire power supply, improves the power supply efficiency and energy saving effect, and at the same time replenishes energy for the starting power supply module; the starting power supply module completes the power supply triggered by the power module from dormancy to activation Continuously output electric energy in an intermittent manner to provide activation power for the power supply module; the processor module completes the setting of the power supply and real-time power comparison and distribution; the power distribution module translates the power distribution code output by the processor module into the corresponding power supply power module control level. The acquisition module is a high-precision resistor I for collecting voltage signals and a Hall current sensor J for collecting current signals, and the two signals are sent to the power calculation module H at the same time.

The preferred power supply module is a plurality of parallel connected power supply modules.

The preferred power supply module can all or partly enter a dormant state or an active state.

A preferred processor module is a DSP chip.

The cognitive power supply involved in the utility model is to make various power supplies, especially high-power continuous-working power supplies, control the proportion of their own power components, transformers, etc. to work in real time according to the working conditions of their loads.

Judging from the current situation of electrical equipment, it can be roughly divided into:

⑴ Segmented work: such as working during the day and resting at night, working at night and resting during the day, etc.;

⑵Intermittent work: Usually the standby power is very small, and the power increases in pulses during work (CT machines, X-ray machines, compressors, etc.);

⑶Random work: Most of the time it is in standby mode, and occasionally works for a short time according to external conditions (ventilation fan, camera, alarm, etc.).

Power control part: It can control whether the power part of the power supply (including the transformer) enters a dormant state or activates a working state. In particular, it can learn and summarize a set of power control procedures according to the working law of the load, and then determine the command to issue sleep or work by analyzing the load parameters provided by the power sensing components. In particular, it is possible to store, analyze, and summarize the information sent by the detection circuit from sleep to work, find out the working law of the corresponding load, and learn to control the ratio of sleep or wake-up of power components. The main problem to be solved here is that when the load increases or decreases, its proportion can be quickly judged, so as to issue corresponding commands to the power components.

With the development of power electronic control technology, the current control chip has been able to conveniently realize the organic unity of the time and security of the mutual conversion between the system from sleep to activation and wake-up. The energy-saving efficiency and working reliability of the power supply during sleep to wake-up process are greatly improved.

  Power supply components: Provide all the power supply energy required by the load, and can easily enter the dormant state or be awakened to enter the working state under the command of the control signal. Generally, multiple modules are connected in parallel to achieve the effect of partly sleeping and partly working. For this reason, the power modules in the utility model can not only communicate and coordinate with each other in voltage and current conveniently, so as to ensure the maximum efficiency of each module, but also quickly and safely complete from sleep state to wake-up Interchange between working states.

Power sensing component: In addition to knowing the change of the load power in real time, notifying the control component to complete the control of the output voltage and current, and protecting the load when it is overloaded or short-circuited, its main function is to Detect the output and load status, find various changes in the load at any time, and quickly send the corresponding information to the power control part.

The perception component with DSP as the core can monitor and judge the load change at any time. When the load increases, decreases or is turned off, it can detect and issue control commands in μs time to ensure targeted sleep or wake-up of power components.

At present, although there are many types of electrical equipment with different working characteristics, they can be divided into full-load operation, no-load operation (load shutdown), and partial operation (half power, small half power, high half power, etc.) in terms of power consumption. In addition, from the current design habits and reliability requirements of power supplies, most power supplies use power redundancy in exchange for their reliability and warranty period. And the current working condition of the power supply system is: as long as the input switch is connected, it will be put into operation with full power. This will inevitably lead to the reduction of the efficiency of the power supply itself, the inactive loss of the total energy and the ineffective shortening of the life of the internal components of the power supply. After the power supply with cognitive function is turned on, it first detects the size of its load, and then decides which modules of the power part are active and which modules go to sleep on the basis of meeting the power and reliability requirements. According to this mode, the detection part tracks the change of the load at any time to change the output ratio of the power components. To achieve the purpose of reducing power loss and prolonging the life of components. During the whole power supply working process, the control part is studying and summarizing the relevant load working rules at any time, and finds out its main working rules to help improve work efficiency and response speed.

The purpose of this utility model is exactly:

(1) Solve the problem that it will continue to work at full power regardless of the load after the power is turned on, but it always consumes a large power.

(2) Reduce the self-consumption of some power components and transformers under light load conditions to prolong their working life.
