Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0026] see Figure 1-3 , the present invention provides a technical solution: a novel wireless induction coil sensor power supply method:

[0027] The wireless power supply first uses the signal generator to generate a signal of the frequency that needs to be resonant, and then amplifies the signal through the power amplifier circuit, and provides it to the energy sending coil. The power transmitting end and the power receiving end in the energy sending coil c...

Abstract

The invention discloses a novel wireless induction coil sensor power supply method. According to the invention, a signal generator generates a signal with a frequency needing to generate resonance, and provides the signal to an energy transmitting coil, the energy transmitting coil and a capacitor form resonance, and a power signal is outwards transmitted to an energy repeating coil; the energy relay coil relays energy of the transmitting coil to the receiving coil, the receiving coil and the internal capacitor form a resonance circuit, changes of an electromagnetic field are detected, a resonance phenomenon occurs to form current, finally, a power supply needed by a load is formed through the voltage-stabilized power supply, and a power supply used for working of the sinusoidal signal generator is generated through the DC power supply. A sinusoidal signal generates two complementary sinusoidal power supplies through the signal up-down power operational amplifier, the two sinusoidal power supplies are provided for the capacitor array and the transmitting coil to generate resonance, the resonance is transmitted to the space in the form of electromagnetic waves, a resonance circuit formed by the capacitor array and the power receiving coil forms alternating current, and then direct current voltage is formed through the bridge rectifier circuit. The direct current voltage is supplied to a charge pump for storing the energy.

Description

technical field [0001] The invention relates to the technical field of wireless power supply, in particular to a novel wireless induction coil sensor power supply method. Background technique [0002] In the traditional aviation and aerospace fields, the power supply of sensors mainly relies on the aircraft and spacecraft power distribution system to supply power through power lines and signal transmission through signal lines. For aircraft and spacecraft that are relatively complex and have high volume requirements, a large number of power lines and signal lines bring great difficulties to the effect of weight reduction. Contents of the invention [0003] The purpose of the present invention is to provide a novel wireless induction coil sensor power supply method to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a novel wireless induct...
