  • Power management circuit and power management method for triboelectric nanogenerator, and energy system
    Patent number: 11394318
    Abstract: The present disclosure provides a power management module, a power management method and an energy system for a triboelectric nanogenerator. The power management module is configured to be electrically connected to a back end of the triboelectric nanogenerator, the power management module includes a rectifying circuit and a Direct Current (DC) buck circuit. The rectifying circuit is electrically connected to the back end of the triboelectric nanogenerator for rectifying a signal generated by the triboelectric nanogenerator to output a first DC signal, and the DC buck circuit is electrically connected to a back end of the rectifying circuit for decreasing a voltage of the first DC signal to output a second DC signal. The power management module may maximize and autonomously release the energy of the triboelectric nanogenerator, and perform a buck conversion for charging the energy storage device or directly driving the electronic device.
