Problems solved by technology

However, due to the high internal impedance of the existing triboelectric nanogenerators, it is easy to cause an impedance mismatch with the energy storage unit.
Therefore, the energy storage efficiency of the existing triboelectric nanogenerator energy storage technology that first rectifies and then directly stores the rectified voltage into the energy storage unit is extremely low, and the energy storage efficiency is only less than 1% as measured by experiments, a large amount of energy wasted for no reason
[0003] For the above technical problems, there is no good solution in the prior art

Abstract

The invention relates to the field of nanometer power generation, and discloses an energy management method, an energy management circuit and an energy management device for a friction nano-generator. The energy management method of the friction nano-generator comprises the steps of: storing electric energy output by the friction nano-generator temporarily in an energy temporary storage; and transferring the electric energy temporarily stored in the energy temporary storage to an energy storage. By adopting the technical schemes, the charging of the energy storage is realized through charging and discharging the energy temporary storage periodically, the impedance matching of the friction nano-generator and the energy storage is realized, and the energy storage efficiency is significantly improved, thereby the AC electric energy generated by the friction nano-generator can be efficiently converted into a constant-voltage direct current for output.

Description

technical field [0001] The invention relates to the field of nano power generation, in particular to an energy management method, circuit and device of a friction nano generator. Background technique [0002] Since 2012, nanogenerators based on tribostatic effects have developed rapidly, and with their high-efficiency output, simple process, and stable performance, they provide a promising way for converting mechanical energy into electrical energy to drive electronic devices. . However, due to the high internal impedance of the existing triboelectric nanogenerator, it is easy to cause impedance mismatch with the energy storage unit. Therefore, the energy storage efficiency of the existing triboelectric nanogenerator energy storage technology that first rectifies and then directly stores the rectified voltage into the energy storage unit is extremely low. The energy storage efficiency is only less than 1% as measured by experiments, and a large amount of energy wasted for ...
