Friction nanogenerator (TENG) power management system design based on L-shaped travel switch

The invention discloses a friction nanometer generator (TENG) power supply management system design based on an L-shaped travel switch, and on one hand, the problems of voltage limitation and electric energy leakage in an electronic switch in the prior art are solved, and the system becomes a first V-Q curve capable of meeting maximum power transmission when a transition capacitor is charged at the same time; and when the energy is transferred to the energy storage circuit, the switch of the maximum value point of the internal capacitance of the TENG is automatically tracked. Different from a conventional TENG switch which is only suitable for a contact separation type, the switch provided by the invention can realize optimal energy transfer point tracking of TENG in four modes (a contact separation type, a single-electrode type, a sliding type and an independent layer mode), the switch provided by the invention can be used for realizing optimal energy transfer point tracking of the TENG in four modes (a cont
