Embodiment Construction

[0025] specific implementation plan

[0026] figure 1 It is a simplified structural block diagram of the capacitive wireless energy and two-way signal transmission system of the present invention.

[0027] This solution mainly includes two parts: an energy transmission channel and a signal transmission channel, wherein the signal transmission channel includes a forward signal transmission channel and a backward signal transmission channel.

[0028] For the energy transmission channel, the energy emitted by the power transmitting power supply is separated by the common-mode differential mode separation circuit, then transmitted to the receiving side through the C1 / C2, C3 / C4 coupling capacitors, and then transmitted to the power receiver through the common-mode differential mode separation circuit circuit.

[0029] For the forward signal transmission channel, the signal sent by the signal transmitting power supply, after being separated by the common-mode and differential-mode...

Abstract

The invention relates to an electric-field-type wireless power and two-way signal transmission system, and belongs to the technical field of nonelectrical contact power transmission. The electric-field-type wireless power and two-way signal transmission system comprises an energy transmission channel, a forward signal transmission channel and a backward signal transmission channel. The energy transmission channel includes a power transmission power source, an energy coupling mechanism, and a power receiving circuit. The forward and backward signal transmission channels each include a signal transmission power source, a signal coupling mechanism, and a signal receiving circuit. The energy transmission channel and the signal transmission channel operate separately through a common-mode differential-mode separation circuit. The electric-field-type wireless power and two-way signal transmission system can realize the synchronous transmission of the energy and a bidirectional signal. The energy channel and the signal channel do not interfere with each other. A wireless power and signal simultaneous transmission circuit designed by according to a common-mode power transmission and differential-mode signal transmission operating principle does not need an additional signal path and a complex control system. The coupled inductive common-mode differential-mode separation circuit compensates the coupling capacitor and simplifies a compensation network.

Description

technical field [0001] The invention proposes a scheme for an electric field type wireless energy and two-way signal transmission system, which belongs to the technical field of non-electrical contact power transmission. Background technique [0002] Power transmission through wires is the most common way of supplying electricity. Non-contact wireless power transmission has the characteristics of flexibility and ease of use compared with wired power transmission. Compared with magnetic field coupling, electric field coupling has the advantages of light emitting board and receiving board, low price, small loss on the transmitting side, The coupling mechanism does not require ferromagnetic materials and will not cause eddy current loss to surrounding metal objects. [0003] In actual work, the electric field coupled wireless power transmission system is greatly affected by factors such as operating conditions and environmental changes, such as changes in the position of the t...
