Example Embodiment

[0026] The embodiments of the present invention will be described in detail below in conjunction with the drawings.

[0027] This embodiment is implemented as follows: figure 1 As shown, an omni-directional selective wireless power transmission system includes a power module 1, a transmitter 2, a plurality of receivers 3, and a load module 4. The resonance frequency of each receiver is different, the power module 1 and the transmitter 2 The frequency can be adjusted to match each receiving end.

[0028] Moreover, the power module 1 converts 220V 50Hz alternating current into high frequency alternating current. The power module 1 includes a high frequency inverter power supply 1-1 or a signal amplification power supply 1-2. The high frequency inverter power supply 1-1 includes a rectifier circuit 1-1-1 and an inverter circuit 1-1-2. The signal amplifying power supply 1-2 includes a signal source 1-2-1 and a power amplifier 1-2-2. The transmitting terminal 2 includes a compensatio...

Abstract

The invention relates to the technology of the radio energy transmission, and specifically relates to an omni-directional selectivity radio energy transmission system. The system comprises a transmitting end connected with a power supply module, and a load module connected with multiple receiving ends; the frequency of the transmitting end is adjustable and is matched with the resonant frequency of each receiving end. The transmission system can satisfy the energy supply to multiple receiving ends at any location of the space by only needing one transmitting end, and the transmission system has the selectivity function at the same time, the energy is only supplied to the receiving end needing the energy in the specific time slot, the energy utilization efficiency is improved, and the loadservice life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of wireless power transmission, and in particular relates to an omnidirectional selective wireless power transmission system. Background technique [0002] Most of the research on resonant magnetic coupling wireless power transfer focuses on unidirectional transmission, and only a few have conducted research on omnidirectional wireless power transfer. With the advent of the era of the Internet of Things, more and more dense sensors are laid, and energy supply is provided by unidirectional wireless power transmission, which requires the same number of wireless power transmitters and receivers as sensors, which is huge in number and poor in economy. Some scholars have proposed an omnidirectional transmitting coil, which can supply energy to multiple receiving terminals in space with only one transmitting terminal, which greatly reduces the number of transmitting terminals for wireless power transmission and al...
