Abstract

The invention discloses a hybrid modeling method of an ECPT system with a load self-adaption characteristic. The method comprises the following steps: according to the on / off conditions of a switchingtube S, a diode D and switching tubes S1-S4 of a full-bridge inverter, setting a plurality of working modes for the ECPT system, and determining a state space equation corresponding to each working mode; determining the boundary conversion conditions among the working modes according to the boundary conversion conditions of a Buck converter and the boundary conversion conditions of the full-bridge inverter, and establishing a hybrid automaton model of the ECPT system according to the state space equation corresponding to each working mode and the conversion conditions among the working mode.The ECPT system model established through the method provided by the invention is more accurate, can simplify a control problem of the ECPT system into a boundary calculation and selection problem, and provides a new idea for realizing the control of the ECPT system with the load adaptive characteristic.

Description

technical field [0001] The invention relates to the technical field of wireless power transmission, and more specifically, relates to a hybrid modeling method of an ECPT system with load self-adaptive characteristics. Background technique [0002] WPT (Wireless Power Transfer, wireless power transfer) technology uses soft media such as magnetic fields, electric fields, lasers, and microwaves to realize the non-electrical contact transmission of electric energy from power supply systems to electrical equipment. Among them, the power transmission method based on electric field coupling has the advantages of simple and thin power coupling mechanism, low cost and variable shape; in the working state, most of the electric flux of the electric field coupling mechanism is distributed between the electrodes, and the influence on the surrounding environment The electromagnetic interference is very small; when there is a metal conductor between or around the electric field coupling me...
