Description

201110497, invention description: [Technical field of invention] As shown in the figure, the method of "output power chasing" is set, and the previous method: (4) method and control device for power transmission between the load terminals, With the second picture. The first graph is a schematic diagram of the relationship between the output voltage and the output current, IlGad, and the output device and the load. - as a general transmission, the energy output device with the internal battery 10, for example,

‘The maximum output power cup with its inherent design _ 自 self-powered lightning 1 past}. The relationship between the maximum output power p_max and the output_V(10), H current Iload is given by equation (1). P_max_ = Voutx Il〇ad ... (1) According to the formula (1) ', when the maximum output power p_max is constant, the input I v〇ut is inversely proportional to the output current Iload, as shown in the first figure. However, in reality, the battery in the energy output device is not a straight line. The (DC) power supply has a battery internal resistance Rbat. At the same time, the output device 1 itself also has a device internal resistance. Runit. Therefore, as the load and l〇ad become wheat, the output current Iload of the 1 output device 1 will increase, and the battery current Ibat will increase accordingly. At this time, the energy consumed by the battery 1's own battery p-block Rbat (pbat=RbatxIbatxIbat) is also added accordingly with reference to the second figure. According to the calculation of the ohm theorem, the output current Iload can be estimated according to the formula (2).

Vbat=(Runit+Rload)x Iload+Rbatx Ibat...(2) Referring to the second figure, it is known from the circuit relationship that Il〇acj is proportional to ibat, which is proportional to 201110497. It can be assumed that the coefficient is α, and the battery current is ibat and output. The relationship between the currents I1〇ad is Ibat=α X Iload. After formula (2), formula (3) can be paid. According to formula (3), the total load impedance (Runit+Rload) can be calculated. (Runit+Rload)=Vbat/Il〇ad- ax Rbat-*-(3) According to the iv's total load impedance (Runit+Ri〇ad) actually received between the output power Pout and the output current Iload The relationship is as in formula (4)

Poutz=(Runit+Rload)x Il〇ad2-**(4) Organize formulas (3) and (4) to know the formula

Pout=(Vbat/Iload-ax Rbat)x Il〇ad2---(5) Also, after formula (5), formula (6) can be known. (6) p〇ut=Vbatx Iload-αχ Rbatx Iload2· (6) 'Assumption】 bat= 4" ω, in the case of -,, 曰 clothes output current Iload and total load impedance (Runit + RJ d real output power Pout relationship waveform diagram, such as 帛三图^ According to the h眚ιίίί,, the figure can be seen that in the early stage of the waveform diagram, the output load pout received by the total load f Γ 会 will increase with the output current ii 〇 ad > p :, 丨ΐ P_max point The total load impedance actually receives the output power J 1 takes a large value. Subsequently, the larger the output current I1〇ad, the total load impedance 4 = close, the output power p- is smaller. Therefore, when the output current iiGad is over The battery 1 itself is her second rfi far greater than the energy provided by the total load impedance, so the output power p(10) received by $ ΐ ίί ^ ί is reduced, and the situation is reduced when entering the Qin effect sheep.
