Abstract
The utility model discloses an inducer for the inverter of a digital generator. The inducer comprises a magnetic core; and the magnetic core is formed by convoluting and notching iron base amorphous materials or nano-crystalline materials. Coils are wound around the iron core, the number of the coil groups is two, and the direction of the magnetic force line of each group of the coils is identical. Because the two groups of the coils are wound around one iron core, the inducer has the advantages of large inductance quantity compared with the traditional inducer; at the same time, the loading capacity is strong, and the use demands can be satisfied by one such inducer required for each inverter.
Description
Technical field
The utility model relates to the inductance in the used inverter of a kind of digital electricity generating group.
Background technology
Digital electricity generating group (claiming inversion motor, frequency conversion generator again) is a kind of generator of AC-DC-AC.The three-phase alternating current elder generation rectification that permanent magnet generator sends is a direct current, and another mistake becomes stable 50Hz of voltage or 60Hz sinusoidal ac, and rectification, inversion, voltage stabilizing etc. are all finished by inverter.Inverter is the part of the most critical of digital electricity generating group, and its performance height has directly determined the performance height of whole generating unit.The principle of inverter inversion is that switching device carries out break-make control, makes output obtain that a series of amplitudes equate and pulse (PWM) that width does not wait, replaces sine wave with these pulses.Filter inductance is all arranged in inverter, and it is used for leaching the high-frequency harmonic in the alternating current of switch controlled output.The performance of this inductance is to the waveform of the output AC electricity of this inverter, and the load capacity of inverter has been played crucial effects.Two inductance of the normal use of inverter controller at present, each inductance has only a winding, connects two output lines of interchange respectively, and inductance adopts FERRITE CORE, has cut air gap on the magnetic core, and the inductance inductance value of this structure is relatively all smaller.For obtaining output waveform preferably, have to improve the switching tube frequency, this consequence of bringing makes output current be difficult to strengthen, the power of restriction inverter, and HF switch has been brought bigger electromagnetic interference.
The utility model content
At the prior art above shortcomings, the purpose of this utility model provides the digital generator inverter inductance that a kind of inductance value is big, load capacity is strong.
The technical solution of the utility model is achieved in that the digital generator inverter inductance, comprise ring-shaped magnetic core, magnetic core is provided with breach logical and interior ring, breach is embedded with non-magnetic filling supporter, be wound with coil on the magnetic core, it is characterized in that: described coil is two groups, and the magnetic line of force direction of every group of coil is identical.
Further, described magnetic core is Fe-based amorphous or nanocrystalline material.
Described two groups of coils all adopt the coiling of multiply enamelled wire, to solve the skin effect of electric current.
Two groups of coils are having two kinds of coiling modes on the magnetic core: 1, stack coiling: wherein one group of coil winding is organized coil winding on last group of coil with another again on magnetic core earlier, and two groups of coil rotation directions are opposite; 2, separately coiling: two groups of coils are wound on the magnetic core independently of one another, respectively account for magnetic core half, two groups of coil rotation directions are identical.
The utility model is compared traditional inductor owing to be wound with two groups of coils on a magnetic core, and this inductance has the big characteristics of inductance value, and load capacity is strong simultaneously, and each inverter only needs such inductor just can satisfy user demand.

Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, as can be seen, digital generator inverter inductance of the present utility model comprises ring-shaped magnetic core 1 from the figure, and magnetic core 1 adopts Fe-based amorphous or nanocrystalline material coiling, otch and make.Magnetic core 1 is provided with breach logical and interior ring and forms air gap thus, and breach is embedded with non-magnetic filling supporter 2.Be wound with coil 3 on the magnetic core 1, described coil 3 is two groups, and the magnetic line of force direction of every group of coil 3 is identical.
Two groups of coils are having two kinds of coiling modes on the magnetic core: 1, stack coiling: wherein one group of coil winding is wound on another group coil stack on the last group of coil on magnetic core more earlier, and this moment, two groups of coil rotation directions were opposite, saw Fig. 2 and Fig. 3.Because the inconvenience of this coiling mode reflects on same figure, so it is divided into two figure; 2, separately coiling: two groups of coils are wound on the magnetic core independently of one another, respectively account for magnetic core half, this moment, two groups of coil rotation directions were identical, saw Fig. 1.
Fig. 1, Fig. 2 and breach shown in Figure 3 are one, and in fact magnetic core also can leave two breach, promptly are made up of two semicircular ring, as shown in Figure 4.
In order to solve the skin effect of electric current, described two groups of coils all adopt the coiling of multiply enamelled wire.
During use, the A of two windings end, promptly illustrated A1 and A2 follow the output of inverter switching device pipe, and the B end of two windings, promptly illustrated B1 and B2 be as the single phase alternating current (A.C.) output of inverter, externally output AC.
