Embodiment Construction

[0012] The present invention will be further explained below in conjunction with the accompanying drawings.

[0013] like figure 1 As shown, a small-power multi-load wireless power supply adaptive DC voltage stabilization system includes an adjustable high-frequency power supply system, an energy transmitting total resonator, a wireless power supply coil array, several multi-energy conversion type DC voltage stabilization systems and low-power multi- load array. The adjustable high-frequency power supply system is used to convert the mains power into high-frequency electric energy for the wireless energy transmission system, and send the high-frequency alternating current with adjustable power to the energy transmitting general resonator. The energy transmitting total resonator includes a high-frequency compensation adjustable capacitor and an energy transmitting coil. By adjusting the high-frequency compensation adjustable capacitor, the energy transmitting total resonator i...

Abstract

The invention discloses a low-power multi-load wireless powered adaptive DC voltage stabilizing system which comprises an adjustable high-frequency power supply system, an energy emission main resonator, a wireless power supply coil array, an adjustable high-frequency compensation capacitor, a multi-energy conversion type DC stabilizing system, a voltage acquisition feedback module and a multi-load array, wherein the multi-energy conversion type DC stabilizing system supplies energy to the load through an energy conversion mode of electromagnetic energy-magnetic potential energy-mechanical energy-electric energy. The low-power multi-load wireless powered adaptive DC voltage stabilizing system solves the problems that a low-power load node is unstable in power supply voltage and is limited in the power supply mode, particularly solves the problems that the sensor node or implantable equipment of human body and the like under an Internet of things system are difficult in power supply and troublesome in battery replacement; the system is stable in power supply performance, has no characteristics of virtual-high voltage turn-off and over-current conduction in a conventional rectification and voltage-stabilizing system, and is high in anti-interference ability.

Description

technical field [0001] The invention relates to a wireless charging technology, in particular to a small-power multi-load wireless power supply self-adaptive DC voltage stabilization system. Background technique [0002] In recent years, with the continuous improvement of people's living standards and the gradual deepening of exploration of the material world, people have new requirements for the transmission method and quality of electric energy. Traditional power transmission is mainly carried out by direct contact of wires or conductors. Sparks generated by contact, sliding wear, carbon accumulation and exposed charged conductors have brought a series of problems. Wireless power transmission is a technology that uses radio to transmit electric energy. It was first proposed by Nikola Tesla. Compared with the traditional power transmission method, there is no direct connection between power supply and power consumption in the process of wireless power transmission. , to av...
