Abstract
A Fe-Si PFC (Power Factor Correction) inductance for an air conditioner solves the problems that the conventional PFC inductance for an air conditioner adopts non-crystalline material to enable the PFC inductance to be expensive in price, large in size, and complicated in mounting. The Fe-Si PFC inductance comprises a magnetic core and a mounting base, wherein varnished wires are arranged on the magnetic core; pins on the varnished wire penetrate through holes in the mounting base, and are used for being connected with an electrical control box of the air conditioner; and the magnetic core is made of Fe-Si powder core material. According to the utility model, as the price of the Fe-Si PFC inductance is more than 30% less than that of the non-crystalline PFC inductance, the PFC inductance made of the Fe-Si powder core material is low in price, the production cost is greatly reduced, the profit is increased, the competitiveness of the product is improved; besides, after the PFC inductance adopts Fe-Si material, the size of the product is reduced, the mounting is convenient and reliable; the Fe-Si magnetic hysteresis telescopic coefficient is 0, so that electromagnetism noise of the inductance is greatly reduced, the noise of the whole machine is effectively reduced, and the Fe-Si PFC inductance is more energy-saving and environment-friendly.
Description
Technical field
The utility model relates to a kind of inductance, is specifically related to a kind of idle call iron silicon PFC inductance.
Background technology
Inductance (Inductance of an ideal inductor) is a kind of attribute of closed-loop path.After coil passes through electric current, in coil, form magnetic field induction, induced field can produce induced current again and resist by the electric current in the coil.The interaction relationship of this electric current and coil is called the induction reactance of electricity, just inductance.The English full name of PFC is " Power Factor Correction ", the meaning is " power factor correction ", power factor refers to the relation between effective power and the total power consumption (apparent power), and just effective power is divided by the ratio of total power consumption (apparent power).When the power factor (PF) value is more big, it is more high to represent its electric power utilance.Present PFC has two kinds, a kind ofly also claims active formula PFC for passive PFC (also claiming passive PFC) and active PFC().The power factor of passive PFC can only reach 0.7～0.8, and it is generally near high-voltage filtering capacitor.And active PFC volume is little, remove to adjust the waveform of electric current by application-specific integrated circuit, and the phase difference between current/voltage is compensated.Active PFC can reach higher power factor--can reach more than 98% usually, but cost is also higher relatively.The PFC inductance is used in convertible frequency air-conditioner Active Power Factor Correction (PFC) circuit, plays the energy storage effect, can effectively suppress harmonic wave, reduces harmonic wave to interference and the harm of electrical network, can also improve the power factor of power supply simultaneously, reduces the loss of electric energy.Existing P FC inductance mainly adopts amorphous band as core material, adds the structure that plastics protect box.There is following defective in this inductance: 1. because non-crystalline material is expensive, manufacture the iron core complex manufacturing simultaneously, cause whole PFC inductance cost higher, be unfavorable for this active PFC technology popularization; 2. because volume is bigger, need in air-conditioning, provide bigger space to install, and its installation process complexity in sky withers.3. certain noise is arranged, be unfavorable for that the level of air conditioner noise promotes.4. because amorphous PFC inductance need be opened air gap in magnetic core, because the air gap loss, there is the problem of local pyrexia in the use, the safe distance certain with this PFC inductance maintenance when needing other device to install.
Summary of the invention
Existing idle call PFC inductance adopts non-crystalline material to make that the PFC inductance is expensive in the background technology in order to solve, and volume is big, the problem of installation trouble, and the utility model provides a kind of idle call iron silicon PFC inductance.
The technical solution of the utility model is: a kind of idle call iron silicon PFC inductance, comprise magnetic core and mounting seat, described magnetic core is provided with enamelled wire, pin on the described enamelled wire passes the through hole on the mounting seat, described pin is used for being connected with pcb board in the air conditioner electric-controlled box, and described magnetic core adopts iron silica flour core material to make.
As a kind of improvement of the present utility model, described enamelled wire is one or more groups, and described every group of enamelled wire is provided with two pins.
As further improvement of the utility model, described magnetic core is annular, U-shaped or EI shape.
As further improvement of the utility model, described magnetic core adopts the moulding of iron silica flour core material compacting sintering.
The beneficial effects of the utility model are, the PFC inductance that adopts iron silica flour core material to make, low price, iron silicon PFC inductance price is more cheap more than 30% than amorphous PFC inductance, reduce production cost greatly, improved and be benefited, increased competitiveness of product, and make small product size diminish after adopting the iron silicon materials, easy for installation, reliable.Because iron silicon magnetic hysteresis coefficient of dilatation is 0, so greatly reduce the electromagnetic noise of inductance, can effectively reduce total noise of centrifuge, more energy-conserving and environment-protective.Iron silicon PFC inductance core material evenly distributes, and need not open air gap in magnetic core with amorphous PFC inductance is the same, so there is not the situation of local pyrexia, has avoided near originally other components and parts can not be installed inductance problem.
