Description
Technical field
The invention belongs to wireless power transmission technical fields, are related to a kind of wireless power transmission with constant current output characteristic
A kind of device, and in particular to magnet coupled resonant type wireless power transfer with constant current output characteristic.
Background technology
Since second industrial revolution, human society enters Electrification Age, the greatly electricity to the various regions that spread all over the world
Net, high-voltage line, small to arrive various household electric appliances, the transmission of electric energy is mainly in direct contact biography by the point-to-point of plain conductor
It is defeated.This " wired " transmission mode brings many problems.Due to there is the problems such as friction, aging, in electric energy transmission process
It is easy to generate spark, and then influences service life and the Electrical Safety of electrical equipment[1].In addition, traditional corded power transmission side
Formula cannot meet the needs of some particular applications, as mine and water are medium.With the development of human social economy, various electricity
Sub- equipment is widely used in a variety of applications, but too many electric wire and socket is made troubles to people’s lives.In addition, implanting
Medical Devices it is long-term power supply also by replace battery there are big inconveniences；The development of electric vehicle is by high cost, height
The wired charging stake of maintainability and low reliability and be restricted.These problems are all calling a kind of electric energy being detached from plain conductor
Transmission mode, i.e. wireless power transmission.
At present according to transporting mechanism difference, wireless power transmission technology can be divided mainly into microwave type, field coupling formula, electromagnetism
Induction type and magnet coupled resonant type.The principle of microwave type is to replace conducting wire to carry out energy transmission using microbeam, but microwave exists
Loss is will produce when being transmitted in air, barrier cannot be passed through, and harmful, be not suitable for using in daily life.Electric field
Coupling formula wireless power transmission is that the wireless transmission of electric energy is realized using the field coupling effect of plate condenser.But plate condenser
Capacitance only have pF ranks, pole plate both ends to will produce high voltage, the high field between pole plate is harmful, in safety problem
In the case of unsolved, it is not suitable for using.Induction wireless power transmission is the electromagnetic induction principle using transformer
Energy transmission is carried out, (is less than 1cm) only under shorter distance, could realize that the electric energy of relatively high power and greater efficiency passes
Defeated, after distance increases, efficiency of transmission dramatic decrease can not live to people and bring improvement.And the nearly 2 years magnetic couplings risen
It is to utilize the electricity with identical resonance frequency, high quality factor using electromagnetic field as medium to close resonance type wireless electric energy transmission technology
Magnetic resonance system realizes the wireless transmission of electric energy in magnetic field based on resonance principle under conditions of weak coupling.Magnet coupled resonant type without
Line electric energy transmission technology is also known as magnetic resonance technology, collection electromagnetic field, microwave engineering, power electronics, Circuit theory, material science
It is a frontier of Now Domestic outer academia and industrial quarters exploratory development Deng in one.Magnet coupled resonant type wireless transmits
System capacity loss is smaller, and transmission range is big, is generally capable of up to 50cm or more, and transmitting coil and receiving coil is not required to have very
Strong corresponding position relationship allows the position offset of zone of reasonableness, energy transmission only to be carried out in resonator system, does not interfere with altogether
Other objects other than vibrating system, without worry foreign matter enter air gap cause damage and keep efficiency of transmission.
The high frequency inverter of magnet coupled resonant type wireless electric energy transmission system and the design of resonator system are key components.
Currently used high frequency electric source Main Basiss bridge type inverting power supply design, traditional bridge type inverting power supply is complicated, needs outer
Add PWM signal generator to realize the driving of switching tube, usually also needs to frequency tracking circuit and realize radio energy transmission system
Frequency-tracking function, inverter driving is complicated, and loss is larger, is usually applied to the high-power field of kilowatt rank,
The application effect in middle low power field is bad；For the electronic product for using electric energy, radio energy is required under some occasions
The electric current of the output of transmitting device is not change with the variation of load, that is, requires wireless electric energy transmission device different defeated
Go out under power condition (load changes), output current remains to keep constant, or only small variation, such as electric vehicle
Just there is constant-current charging phase in charging process.And most of wireless electric energy transmission device can not all realize different bear automatically at present
Constant pressure output under the conditions of load, but the form by the way that DC/DC converters are added in rear class realizes constant current output, is so
The complexity and cost of system improve, and efficiency reduces, and the wide input voltage range of DC/DC converters is also to its structure
Prodigious difficulty.
