Embodiment 1

[0027] The wireless power supply system of this embodiment is divided into two parts, namely a transmitting part and a receiving part.

[0028] Such as figure 1 Shown is a schematic diagram of the principle of the emission part of the present invention. The transmitting part includes a control unit I, a voltage stabilizing unit I, a temperature detection unit, a current detection unit, a voltage acquisition unit, a transmitting unit, a first detection unit I, a second detection unit I, and a third detection unit, wherein the control unit I serves as the main The control part coordinates the work of other units, and the control unit I selects a control chip with pins.

[0029] U1 in the voltage stabilizing unit I uses a TL431 chip, and E1 in the unit is connected to I5 of the control unit to provide a stable DC operating voltage of 2.5V to ensure that the control unit I will not be burned due to high voltage.

[0030] The NTC thermistor in the temperature detection unit is pl...

Abstract

The invention belongs to the field of power supply of power equipment, and particularly relates to a wireless power supply system for providing power for small power equipment. The wireless power supply system comprises a transmitting part and a receiving part, wherein the transmitting part comprises a control unit I, a voltage stabilizing unit I and a transmitting unit; the receiving part comprises a receiving unit; the voltage stabilizing unit I provides voltage for the control unit I; the transmitting unit is connected with the control unit I; the transmitting unit and the receiving unit are connected through an electromagnetic field; the transmitting unit comprises an mos transistor, an mos transistor drive and a first LC resonant circuit; coils L1 and L2 and a capacitor C1 form the first LC resonant circuit; the mos transistor is used for driving the coils L1 and L2; the mos transistor drive is used for controlling on and off of the mos transistor; and the control unit I drives the coils L1 and L2 to generate wireless signals through the mos transistor and the wireless signals are transmitted to the receiving part. Wirelessness of an intelligent home, an intelligent life and power equipment is facilitated, and power supply demands of the power equipment in an electromagnetic field area of the transmitting coil are met.

Description

technical field [0001] The invention belongs to the field of power supply for electrical equipment, in particular to a wireless power supply system for powering low-power electrical equipment. Background technique [0002] At present, the power supply methods of low-power electrical equipment include solar power supply, battery power supply, rechargeable battery power supply, lithium battery charging or power supply through power module connection. It is necessary to provide lines to satisfy the transmission of electric current. This power supply method also brings many disadvantages in the use of power supply. Many electrical appliances compete for the power interface, and multiple power interfaces need to be introduced, which not only brings potential safety hazards in electricity use, but also is not conducive to the realization of smart homes. Especially the application of wireless power supply to the current smart home is a convenient and safe new technology. It does n...
