Abstract
The present invention relates to charger technology, and is one kind of non-contact inducting charger. The charger includes one primary power circuit structure and one secondary power circuit structure. The primary power circuit structure has input connected to the AC power supply and primary winding in the output. The secondary power circuit structure includes rectifier and filter circuit, and has input connected to the secondary winding and output connected to re-chargeable battery. The primary winding is on one semi-ring magnetic core, the secondary winding is on the other semi-ring magnetic core, and these two semi-ring magnetic cores are combined to form one complete ring magnetic core generating ring magnetic path. The present invention charges electric load without any contact and this raise the safety.
Description
Technical field
The invention belongs to the charging device technical field, relate to a kind of non-contact induction type charger.
Background technology
Present normally used charger all is to be connected with load by conductor (power line) when work; therefore may there be electric safety problem; and joint loose contact when pegging graft appears in regular meeting, particularly after long-term the use, may produce phenomenon or faults such as loose contact.Chinese patent bulletin CN2504773Y discloses a kind of " non-contact type charger apparatus ", specifically introduced: this non-contact type charger apparatus comprises a charger and a power brick, be respectively equipped with ultrasonic oscillator and emission resonator in charger inside, be loaded with the reception resonator in the power brick, the emission resonator with the ultrasonic magnetic wave radiation of ultrasonic oscillator in the charger periphery, chargeable power brick is put on the charger outer peripheral areas, reception resonator on its power brick thereby played the resonance effect, the powerful magnetic wave of sensing the charger periphery is arranged, at once convert voltage and electric current to, through one group of rectification circuit, charge into power brick after the rectification.This non-contact type charger apparatus can be realized not needing connection line and reach purpose to rechargeable battery charging, but because this charger includes ultrasonic oscillator, emission resonator, receives resonator, rectification circuit etc., the circuit structure more complicated, and convert electricity to the ultrasonic wave magnetic wave, by receiving resonator magnetic wave is converted to again, conversion efficiency is low, and electric energy loss is big.
Summary of the invention
The objective of the invention is at above-mentioned deficiency in the prior art, provide that a kind of circuit structure is simple, utilization rate of electrical is high, loss is little, do not need directly to be connected with load appliance, only to transmit the non-contact induction type charger of energy during work by electromagnetic field.
The technical scheme that solution the technology of the present invention problem is adopted is: the non-contact induction type charger that is provided comprises primary source circuit structure part and secondary power circuit structure part, wherein the input of primary source circuit structure part is connected with AC power, the secondary power circuit structure partly comprises rectification, filter circuit, its output termination rechargeable battery, the output of primary source circuit structure part is a primary coil, primary coil is on the stem stem of half annular magnetic core body, the input of secondary power circuit structure part is a secondary coil, secondary coil is on the stem stem of second half annular magnetic core body, semi-circular magnetic core array on the primary coil and the semiorbicular magnetic core array on the secondary coil lump together and form complete annular magnetic core body, form complete toroid during work.
The present invention's insulating power supply with common on operation principle is identical with isolated transformer, but basic difference is structurally arranged.Common insulating power supply is one group with the input of isolated transformer and exchanges (or direct current) voltage, give load by the direct voltage that isolating transformer is exported again behind over commutation.Its energy is that the form by electric current and voltage transmits.And the present invention structurally is divided into two parts to the primary coil of isolating transformer and secondary coil, and the magnetic energy of primary coil is as the input of secondary power, and its energy is that the form by magnetic flux in the primary and secondary coil and magnetic flux density transmits.Do not need the connection of conductor because its magnetic energy can transmit by the form in magnetic field, the present invention is a kind of charger of non-contact induction type thus.
When the present invention charges to load appliance, do not need to connect, or plug connector is pegged graft by conductor, can strengthen the fail safe of electricity consumption, the appearance of fault such as connector loose contact can not occur, the size that circuit structure is simple, reduced internal electric source has improved the utilization ratio of electric energy.
