Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.
Example 1, as shown in fig. 1, a power management method for a general friction nano-generator includes the following steps:
the method comprises the following steps: a triboelectric nano-generator (TENG) captures mechanical energy in the natural environment and converts the mechanical energy into electrical energy.
The friction nano generator in the first step is a friction nano generator for collecting environmental sound energy, human motion energy or wind energy.
As shown in fig. 3, the friction nano generator (S-TENG) for collecting environmental acoustic energy includes a friction layer and an electrode, the friction layer and the electrode are installed in the embroidery frame assembly, when the environmental acoustic wave is driven, the friction layer and the electrode are in contact and separated, and as the friction layer and the electrode are continuously separated by friction, an alternating current signal is continuously output from an output terminal, thereby outputting electric energy to the outside. As shown in fig. 4, the friction nano generator (CS-TENG) for collecting kinetic energy of human body drives CS-TENG by human body movement, PTFE is adhered to an acrylic plate, copper foil is used as an electrode, copper foil on the other side is adhered to the acrylic plate, and when the PTFE film contacts the copper electrode, an electrostatic field is generated to drive external electrons to generate electric energy to drive electrical appliances to work. As shown in fig. 5, the friction nano generator (W-TENG) for collecting wind energy fixes the PTFE film on the rotating device, the interdigital electrode is adhered to the acrylic plate, and when wind blows, the rotating device drives the PTFE film to rub against the interdigital electrode, so as to generate an electrostatic field to drive electrons to be transferred in an external circuit to generate electric energy, thereby driving the electrical appliance to work.
Step two: the electric energy output by the friction nano generator, namely alternating current output, is converted into direct current output through a conversion circuit (AC-DC).
As shown in fig. 9, the conversion circuit is a full-wave bridge rectifier, and converts the ac signal output by the friction nano-generator into a dc signal. The output end of the friction nanometer generator is connected with the input end of the full-wave bridge rectifier, and the output end of the full-wave bridge rectifier outputs a direct current signal.
Step three: and chopping and converting the direct current output to realize voltage stabilization and output a direct current signal.
The purpose of the chopping transformation in the third step is mainly to reduce the matching impedance of the triboelectric nanogenerator.
As shown in FIG. 9, the chopping conversion circuit comprises an inductorLCapacitor and method for manufacturing the sameCA diode D and a self-triggering switch which is connected with the inductor in series and then is connected with the inductorThe output end of the conversion circuit is connected, the capacitor is connected with the diode in series and then connected with the two ends of the inductor in parallel, and the two ends of the capacitor are used as the output end to be connected with the input end of the commercial integrated circuit.
A self-triggering switch is critical to maximize energy capture from TENG. The self-triggering switch is a discharge tube; the self-powered electronic trigger switch can greatly reduce the matched resistance, so that the maximum energy output period is realized. The present invention selects commercial discharge tubes as the self-triggering switch because of its good durability and controllability.
The energy transfer method of the chopping conversion can be divided into two stages, which are respectively:
in the first stage, as shown in (b) of fig. 9, the electric energy of the friction nanogenerator is converted into magnetic energy stored in the inductance L: when the voltage on the self-triggering switch, i.e. the discharge tube, exceeds a threshold value, the self-triggering switch is triggered to be turned off, the commercial discharge tubes have different specifications, the common voltage threshold values are 150V, 300V, 470V, 600V, 800V and the like, and the voltage threshold value selected by the invention is 300V. When the diode D deflects reversely and is closed, the friction nanometer generator, the conversion circuit, namely the full-wave bridge rectifier and the inductor L form an electric loop, current passing through the inductor L is generated and gradually increased along with the increase of the current, and once the current reaches the maximum value, electric energy is completely converted into magnetic energy of the inductor L.
In the second stage, as shown in fig. 9 (C), the magnetic energy is converted into dc electric energy stored in the capacitor C: the self-triggering switch is switched off, the inductor L enables the diode D to be biased forwards through the self-induction function of the inductor L, a circuit loop is formed among the inductor L, the diode D and the capacitor C, and the magnetic energy on the inductor L is converted into electric energy and stored in the capacitor C; after energy storage is complete, diode D is reverse biased and closes, closing the circuit between the capacitor C and the capacitor L and allowing energy to be stored in the capacitor C, thereby completing a charge cycle. In addition, considering practical applications, when the instantaneous power of the load is greater than the average power of TENG, the load cannot normally operate. Therefore, the stabilization of the output voltage and the regulation of the output mode are critical to the energy management of TENG.
Step four: and managing the direct current signals in the third step by using a Commercial integrated circuit (Commercial IC), and outputting a stable voltage so as to supply power to a load.
Commercial integrated circuits (Commercial ICs) mainly implement reasonable management of energy captured by TENG, output stable voltage, and implement control of TENG output mode so that it can be used as a power supply to supply power to electronic devices.
The commercial integrated circuit is a BQ 25504 chip or an S6AE101A chip, and the stabilization of output voltage and the regulation of an output mode are realized; the load is connected in parallel on a commercial integrated circuit. The use of the BQ 25504 chip successfully realizes the adjustment of stable output voltage and output mode. For the power management strategy designed by the invention, the BQ 25504 chip is one of the key components. The BQ 25504 chip plays a role in achieving a stable output voltage and adjusting an output mode from a pulse output to a continuous output. Meanwhile, the S6AE101A chip can also achieve the same functions as the BQ 25504 chip to play the roles of voltage stabilization and output mode adjustment.
The commercial integrated circuit can well manage the energy, so that the commercial integrated circuit can realize the control of various output modes, such as continuous output, pulse output, trigger output and the like; therefore, the problem that the load cannot work when the load power is larger than the average power of the friction nano generator is well solved.
