Abstract

The invention discloses a novel PZT-based ultrasonic contactless energy transmission system, which comprises a power supply, an oscillation circuit, a transmitting PZT transducer, a receiving PZT transducer, an energy collection interface circuit and an energy management module, wherein the power supply, the oscillation circuit and the transmitting PZT transducer form a transmitting end of energy transmission, and the receiving PZT transducer, the energy collection interface circuit and the energy management module form a receiving end of energy transmission; and the transmitting PZT transducer resonates with the receiving PZT transducer for transmitting energy. The novel PZT-based ultrasonic contactless energy transmission system adopts ultrasonic waves as a coupling medium, and achieves the contactless transmission of energy through the resonance between the ultrasonic transmitting and receiving piezoelectric ceramic transducers. The novel PZT-based ultrasonic contactless energy transmission system can get rid of the limitations of diaphragm power transmission by taking the ultrasonic waves as a medium, and can perform contactless power transmission within a certain effective distance range.

Description

technical field [0001] The invention relates to an energy transmission system, in particular to a novel PZT-based ultrasonic non-contact energy transmission system. Background technique [0002] As early as 1956, Rosen used ultrasonic energy transmission to design a piezoelectric transformer composed of primary and secondary PZT piezoelectric ceramics (PZT-PbZrTiO3, lead zirconate titanate), which used sound waves for energy transmission. At present, ultrasonic wireless energy transmission is mainly used in medical and aerospace military fields. In the medical field, acoustic energy is transmitted to PZT implanted in the human body through the skin to realize percutaneous energy transmission to implanted medical devices (cardiac pacemakers, etc.). In the field of aerospace and military industry, PZT transducers are used to generate sound waves to supply power to electronic devices working in a closed environment. Similar ultrasonic wireless energy transmission technologies ...
