Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0032] In order to solve the problems existing in the prior art due to the influence of different line resistances of the load lines, over- or under-adjustment of the line loss compensation voltage, and the need to consider the matching problem of the line loss compensation resistance, the present invention provides a method for realizing complete line loss voltage The compensation method and the intelligent power supply circuit are used to automatically and completely compensate the line loss voltage in real time, without considering the matching problem of the line loss compensation resistor and whether there is a difference in the line resistance of the load line.

[0033] Such as figure 1 As shown, the method for realizing full line loss voltage compensation described in the present invention has the main idea as follows: the peripheral de...

Abstract

The invention relates to a method for realizing the complete compensation of line loss voltage and provides an intelligent power supply circuit for realizing the complete compensation of the line lossvoltage. The voltage value of a wirelessly transmitted detection voltage is provided by means of peripheral equipment (namely a load end) and then is converted into an analog value through a CPU; a feedback end, namely a feedback voltage, of a power supply is influenced by the real-time change of voltage difference obtained by comparison, and therefore, the power supply is controlled to adjust anactual output voltage; and finally, the effect of the complete compensation of the line loss voltage is achieved. With the method and the intelligent power supply circuit provided by the embodimentsof the invention adopted, the line loss voltage can be automatically and completely compensated in real time without considering the matching problem of line loss compensation resistance and whether the line resistance of load lines is different or not.

Description

technical field [0001] The invention relates to power supply technology, more specifically, to a method for realizing full compensation of line loss voltage, and an intelligent power supply circuit for realizing full compensation of line loss voltage. Background technique [0002] With the improvement of the performance of electronic devices, the current output required for charging the electronic devices is increasing, and it is necessary to support different load currents, and at the same time, the charging voltage needs to be kept stable. However, due to the line loss voltage drop in the extension line, the power supply circuit in the prior art cannot solve or completely solve the problem of line loss voltage compensation caused by high current or inconsistent load current. [0003] In the prior art, most of the power supply technical solutions for line loss voltage compensation are to increase the line loss compensation resistor compensation voltage on the line. Although...
