Electric current.Mainly being made up of microwave launcher and microwave receiving device, receiving circuit can catch
To the radio wave energy rebounded from wall, then with load adjust while keep stable
DC voltage.
It is disadvantageously, charging interval length (through-put power is low): cannot complete at short notice
Charging tasks；Conversion efficiency is relatively low: a large amount of power that emitter sends are with the form of radio wave
It is wasted.
3, magnetic resonance type charging: transmitting terminal energy runs into the receiving terminal that resonant frequency is identical, by
Resonance effect carries out electric energy transmission, and it is by energy dispensing device, and energy acceptance device composition,
When two devices are adjusted to same frequency, resonate in a specific frequency in other words, they
Just can exchange energy each other.
Its shortcoming is: miniaturization, high efficiency are more difficult, and existence safety is asked with healthy
Topic.
