Friction nano-generator power management module, management method, energy system and friction electronic energy extractor

摘要

PROBLEM TO BE SOLVED: To provide a power management module, a management method and an energy system of a friction type nano-generator, and to belong to the field of power electronics. A power management module is disposed to be electrically connected to a rear end of the friction nano-generator and includes a rectifier circuit and a DC step-down circuit, the rectifier circuit including a rear end of the friction nano-generator. Electrically rectified the signal generated by the friction nano-generator to output a first DC signal, and the DC step-down circuit is electrically connected to the rear end of the rectifier circuit and is autonomous A switch circuit is included to step down the first DC signal and output a second DC signal. The power management module of this disclosure is capable of maximally and autonomously releasing the energy of the friction nano-generator and performing step-down conversion to charge the energy storage device or directly drive the electronic device. be able to.
