Abstract

The invention discloses an energy collection and conversion device based on a friction generator, comprising a printed circuit board, at least one friction generator, an AC / DC conversion module, a trigger module, and an energy storage module. The AC / DC conversion module, the trigger module and the energy storage module are fixedly arranged on the printed circuit board. The AC / DC conversion module is used for converting alternating current generated by the at least one friction generator into direct-current electric energy. The trigger module is used for controlling output of the direct-current electric energy. The energy storage module is connected with the output end of the AC / DC conversion module or connected with a load under control of the trigger module. The invention provides the energy collection and conversion device of which the energy storage element and the energy conversion device are integrated on the PCB, and the energy collection and conversion device can power devices with large power consumption.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an energy collection and conversion device based on a friction generator. Background technique [0002] The triboelectric effect has been discovered by humans for hundreds of years. However, because the output of existing friction generators generally has the characteristics of high voltage, low current and low charge, and the energy output of friction generators is often a Short pulses with variable frequency, so it is difficult to realize continuous power supply for electronic devices with large power consumption, such as MCU. Therefore, it requires energy conversion to drive electronic devices that consume a lot of power. [0003] At present, energy storage devices generally used in energy conversion circuits are electrostatic capacitors, supercapacitors, lithium-ion batteries, lead-acid batteries, etc. Usually, a capacitor is used as a primary energy storage unit, and a...
