Title: ENERGY MANAGEMENT CIRCUIT AND ENERGY MANAGEMENT METHOD FOR TRIBOELECTRIC NANOGENERATOR
Abstract:
An energy management circuit and an energy management method for a triboelectric nanogenerator. The energy management circuit comprises: a pulse current control switch, an intermediate energy storage element, and a target energy storage element. The pulse current control switch is used for instantaneously turning on, after induced electrostatic charge is generated between two electrode layers of a triboelectric nanogenerator due to the movement of two relative motion parts of the triboelectric nanogenerator, the two electrode layers to generate instantaneous pulse current. The intermediate energy storage element is used for storing electric energy of the instantaneous pulse current. The target energy storage element is used for storing electric energy of the intermediate energy storage element. The configuration of the pulse current control switch overcomes the shortcoming of low output current of the triboelectric nanogenerator, so that large instantaneous pulse current can be output, and instantaneous output power is enhanced. Efficient energy storage of a triboelectric nanogenerator (TENG) is implemented by introducing an element having an inductive reactance characteristic as an intermediary for energy conversion and storage processes.
