Abstract

The invention provides a wireless energy extracting device and a power supply control method thereof. The wireless energy extracting device includes: a radio frequency (RF) generator module for sensing an RF charging signal to generate electrical energy; a capacitor module for storing electric energy; and a power supply control module electrically connected with the RF generator module and the capacitor module. When the induction electric energy is greater than the energy consumption demand of an energy consumption device, the wireless energy extracting device directly outputs the induction electric energy to drive the energy consumption device, and the residual electric energy of driving the energy consumption device is transferred and stored in the power supply control design of the capacitor module, so that the energy conversion loss of the capacitor module during charging and discharging can be reduced, and the energy utilization efficiency can be improved.

Description

technical field

[0001] The present invention relates to an energy acquisition device and a power supply management and control method, in particular to a wireless energy acquisition device and a power supply management and control method for the wireless energy acquisition device. Background technique

[0002] With the development of wireless charging technology, wireless charging has begun to be widely used in fields such as mobile devices, electric vehicles and home appliances. Among them, the wireless charging method of radio frequency (RF) charging technology is to transmit a radio wave through a transmitter, and then a receiver wirelessly senses the radio wave and generates electric energy, because the transmitter can charge multiple receivers at the same time , and the wireless charging distance can be extended to more than 4.5 meters, so it has gradually become the mainstream in the field of wireless charging.

[0003] In the current radio frequency charging technolo...
