Abstract

The invention discloses a low-power-dissipation circuit energy collecting circuit. The low-power-dissipation circuit energy collecting circuit comprises a rectifying and voltage-stabilizing module, a boosting module, an enabling output module and a voltage reduction module. The input end of the rectifying and voltage-stabilizing module receives an external alternating current and is used for converting the external alternating current into a direct current, and the output end of the rectifying and voltage-stabilizing module is electrically connected with the input end of the boosting module; the boosting module receives the direct current, and the output end of the boosting module is electrically connected with the input end of the enabling output module; the enabling output module receives a direct current obtained after boosting and is used for throttling the direct current obtained after boosting, and the output end of the enabling output module is electrically connected with the input end of the voltage reduction module; the voltage reduction module receives a direct current obtained after throttling and is used for reducing the voltage of the direct current obtained after throttling. According to the low-power-dissipation circuit energy collecting circuit, threshold voltage is set through the throttling function of the enabling output module, energy is output from the boosting module to the voltage reduction module, and due to the working mode that boosting and voltage reducing are sequentially carried out, continuous energy supplying to the outside can be achieved.

Description

technical field [0001] The invention relates to the technical field of low power consumption circuits, in particular to an energy collection circuit for low power consumption circuits. Background technique [0002] With the continuous development of electronic technology, more and more low-power circuits are used in circuits. This is because the low power consumption circuit can reduce the heat generated by the circuit while reducing the energy consumption of the circuit and saving resources, which is of great significance for maintaining the stable operation of the circuit. [0003] Furthermore, energy harvesting is the most important part of low-power circuits, which can effectively manage energy. However, because the energy source has the characteristics of discontinuity, instability, and non-polarity, the energy harvesting circuit in the prior art can only collect energy for a specific energy source, and cannot realize energy harvesting for low-power consumption circuit...
