Description

1308812
IX. INSTRUCTIONS: / TECHNICAL FIELD OF THE INVENTION The present invention relates to a single-parameter dynamic adaptive damping surface-closing method, a circuit, and a device using the same, which can be applied to any device that requires a power supply. A technology that effectively manages power supplies. [Prior Art] • For the use of the Micro-Mobile Platform, such as mobile phones, personal digital assistants, laptops and Μ P 3, c D φ music, MpEG4 movie playback devices, internal power supply Design is always an important issue. When people's demand for mobile computing and communication continues to increase, it is more demanding to provide a stable and long-lasting power to ensure that all equipment can go online. However, any device that requires electricity today relies on battery-powered batteries. Once the battery power drops and needs to be recharged, these devices are completely ineffective due to lack of power. In view of this, how to develop and design a long-duration power supply is a top priority, and design a power-saving device for the power supply without changing the existing appearance and internal wiring. Effectively saving energy is a big challenge. [Summary of the Invention]
Intermittent power-off and power-supply action, one of the purposes of this is to provide a method to actively store the excess power of the power supply to the load. In terms of the power supply side, the power supply side is extended to extend the use time of the power supply. Electrical efficiency achieves the goal of saving electricity. In the year of 1308812, it is called the moon and the moon to achieve the above-mentioned purpose. The method of the present invention is to set a storage area between the power supply side and a load side connected to the power supply side, so that the energy is temporarily suspended. The storage area is connected in parallel with the load side. When the power supply side supplies power to the load, the energy temporary storage area actively absorbs excess power of the power supply side and stores it; after the power storage is saturated, the load is discharged while the power supply side is cut off. The output of the energy temporary storage zone is formed by a dynamically adaptive damping connection-storage element. Yet another object of the present invention is to provide a single parameter dynamic adaptive damper damming circuit that stores excess power of the power supply and then feeds the stored power back to the load. The single-parameter dynamic adaptive damping coupling circuit comprises: a power supply side, which can output an average current; a load is connected to the output end of the power supply side; and a dynamic adaptive damping is connected to the output of the power supply side And the parallel connection with the load; ', an energy storage component, is connected with the dynamic adaptive damping; wherein, when the power storage of the energy storage component is saturated, the load is discharged while the output of the power supply side is cut off, so that The power supply measures intermittent power supply, thus extending the effective power supply time on the power supply side. [Embodiment] Regarding the circuit design principle part of the present invention, please refer to the circuit diagrams of the current source and the voltage source respectively, which are according to the κ丨rchhoff theorem. It can be expressed as the following second-order differential x-path: θ (1) l3〇88l2 di d2i dt2 IcJt LCi = Icl or expressed as a matrix: -- _ 1 1Ί V ~RC ~c V 1 . *~~l. 1 . + c 1 L i 0 l 0 d\ R dv • + — -- — .

In the above formula, f is called the resonance frequency. The damping value of the system can be brought close to the resonance state by setting the appropriate R. R 1308812 has a squared term, so the change is sensitive, and the thermistor itself can be used. The temperature changes its own resistance value, and the adjustment of the latch value in the above formula achieves appropriate impedance matching. Since the thermistor is added, the circuit of the original current source has been "temperature, Parameterized ' (parameterized heart temPerature), more added, temperature, this can be controlled factor. In addition, if it can be maintained in the resonance response area, can be coupled without consuming (c〇up ||ng) and extracting excess power into the temporary storage area, #This will effectively reduce the operating temperature of the original system and system, and the power consumption can also decrease with the good coupling of the working environment. To achieve the purpose of power saving. The above explanation of "excess power" is as follows: When considering a circuit having a resistive load R and the input voltage is 乂, the wheeling voltage is expressed as · ^ cos ί · 0 regarded as eight in the maximum input voltage direct current, the current / will be set according to Ohm is:
And what is the average power in the complete cycle (five)? 2 R .......(4) Power? Not equal to real power, but must pay attention to the average of the above formula (4) Ρ - ^0 ~ Ύ 7 (5) Ϊ 308812 In fact, the average power is only half of the real power: Sound = Seto, in other words, the power supply as long as Half of the real power (ie, average power) can work with the second load. When input with real power, half of the excess power is dissipated into the atmosphere by heat and electromagnetic waves, which is not really work. The voltage 岣 root value \ / let: V = ii-rm! Stone = 0J07V0 where, only the maximum voltage \ / 〇 70%, the average power is the square root of the rms and 2 conductance The product, as shown in equation (6): (6) R ^ rms^rms p^YL· · Therefore, if you want to add power-saving features to the system architecture and design, it seems that only AC power can be achieved, but the AC power supply has Unable to store, not portable, and other difficult to overcome shortcomings, so today's electrical appliances are built-in rectification (rectification) and storage battery (battery) and other compromises. In general, in a circuit that uses a DC power supply as the power supply, the DC voltage can be adjusted to a controllable duty cycle and boosted to the voltage required at the load. The output power can be nearly (6). The most common way to average power is to use an inverter. However, if the excess electric energy is to be recycled and reused, the inverter cannot meet this requirement. Therefore, the present invention incorporates a coupling circuit of dynamic adaptive damping (dynamjc-adaPtive damper), and the coupling circuit is connected in parallel with the original On the power supply line, the dynamic adaptive damping is kept constant less than the impedance of the system load. As shown in the equation (3), the R value becomes smaller as it becomes smaller (but it must be avoided too small, otherwise the power will directly enter the energy The storage area and 1308812 will not be output to the load), and the output current will be directed into an energy temporary storage area. As the boosting light combining circuit enters an energy storage unit, the stored excess will be collected once the stored power is saturated. The power is returned to the load and also blocks the power supply on the power supply side. As far as the power supply side is concerned, 'there is an intermittent power-off and 'power-supply action, thus prolonging the use time of the power supply' to improve the power efficiency. Achieving power-saving purposes" The stomach is shown in the second figure, which is a dynamic adaptation of the present invention. The circuit principle of the damper is not considered. The circuit generally comprises a battery (10), a frequency converter connected to the battery (1 〇), and a load connected to the output end of the frequency converter (丄 △ I). (20) an energy temporary storage area (30) parallel to the load (2〇), the energy temporary storage area (3〇) having dynamic adaptive damping (3 and an energy storage element (3 2), The energy storage component (3 2 ) can be connected in series with a matching switch (3 3 ). The circuit principle can be explained by three parts: 'Part 1: Power generation and collection, generally using DC power supply negative load (2 0) The electricity is stored in a battery (worker). When the line is turned on, the power flows directly into the load (2 〇) with a fixed DC power supply. The type of power used is power consumption. But the power is reasonable. The way is to use the average current instead of the full amount. In the present invention, the DC power source outputted by the battery (1. 〇) is converted into a DC power source having a pulse wave modulation after being converted by the inverter (1 1 ) (DC v〇Hage with pWM) Modulated DC (1 2 ), modulated straight L ( i 2 ) is output to the load (2 Q ) in the form of average electric (丨i, 丨normal). Part II: After the average current is generated, On the one hand, the power is sent to 1308812] load (2〇), and the excess power is coupled into the energy temporary storage area (3 〇), with the dynamic damping (3丄) variability damping Zi (virtual load virtua丨)丨oad), its impedance Zj must be smaller than the impedance of the load (2) (Zi<Z(5Ut), which becomes the dynamic damping of the working environment, the shape resonance, and it does not consume power or the damping ratio. ' = zero coupling. On the one hand, the electric field strength is pulled up, and at the same time, the coupling has a gate frequency of direct current (丨i), so the dynamic adaptive damping (3 1 ) can recover 0 and re-human feed into the system. When entering the energy staging area (3 〇), the power will be stored in the high-frequency DC The capacity of the energy storage component (3 2 ), ^ 储月匕 tl (3 2 ) can be made up of a capacitor or a battery. As long as the circuit functions normally and the dielectric material is not lost, it will be continuously charged/discharged. And feedback excess power. When the dynamic adaptive damping (3丄) starts with the load (2 〇) and: 'the impedance value is bound to be small (Zi<z〇ut), the electric & I丨 can enter the The energy storage element is stored in the storage tank b 7L piece (3 2 ), and the energy stored in the energy storage element (3 2 ), the amplitude of the output voltage, etc. can be determined according to requirements. The third part: for the output coupling unit, because the output will have a load effect, so in the actual application, another resistance circuit is needed. The function of the circuit must also have the function of dynamic impedance matching, when the power storage is saturated. At the time of 'discharging the load (2 0 ) (lburst), it also cuts off the output of the battery (丄' 〇) end power (丨 ―). From the load (2 〇) side, the obtained power is alternately supplied by the electric current / battery C 1 ϋ ) and the storage element ( 3 2 ) in alternating current (丨 normal ' lburst). The load (2〇) terminal can be driven with minimum power (ie half power), and the excess power, 1308812 is recycled and reused to save power. The battery (10) stores the same power but the usage time is Can be extended 'can also protect the power supply from overloading. Since the system is equipped with the energy temporary storage area (3 〇), when a short circuit occurs, the generated large current can be detected by dynamic adaptive damping (3 1 ) and simultaneously change its impedance to balance and absorb, thus preventing The damage caused by the short circuit and the supply of electricity is isolated. If an unexpected high electric field strength is input, the dynamic adaptive damping (3 1 ) can also detect this electric % and simultaneously change its own impedance to balance and absorb, thus isolating the destruction of high electric field strength. As shown in the fourth figure, an embodiment of the dynamic adaptive damping (3 1 ) of the present invention includes: a thermal temperature element (3 1 Q ) connected to the modulated direct current (1 2) and an inductor (3) 1 1) Between; a Schottky diode (312) whose positive end is connected to one end of the inductor (3 1 1 ), and its negative terminal is connected to a capacitor (3丄3) and then grounded, capacitor (313 At the same time, there is a parallel adjustable voltage (314); a transistor (3 15), one end of which is connected to the positive end of the Schottky diode (3 1 2 ), one end is grounded, and the base is connected to the base An output of an oscillating circuit (316).

Since it is in the case of on-line or off-line, it is called full-time. FuH-time un-interruptible power supply 〇 Under the architecture based on the third graph, the circuit of the UPS includes: turbulent supply unit (40) ww π τρ 澄The AC power is transmitted through the transformer to the rectifier circuit.
