Abstract
The invention relates to a high-specific-energy direct/alternating (flat wave) public (dual-purpose) (high-voltage) generator with a distortionless waveform, which is a direct/alternating public (dual-purpose) generator with a direct-current generating winding using a direct-current winding drum type coil.
Description
Technical field
The distortionless high specific energy of waveform is handed over straight (flat ripple) to be total to (two) and is used high-voltage generator.
Background technology
The DC-AC two-use generator of using in independent place such as restricted clearance such as aircraft, military vehicle, submarine, warship oceangoing ship, offshore platform before this all is to overlap three phase windings with two.One cover is exclusively used in alternative electric generation, another set of or with a plurality of three-phase declinate degree distribute 12 equate windings, again through bridge rectifier (12 phases or string or also) acquisition direct current.Shortcoming is that bridge rectifier produces wave distortion, the direct current fluctuation is also big, but also has influence on the another set of waveform that exchanges special-purpose (3 phase winding) electricity on the stator that coexists.
Summary of the invention
Schematic diagram 1 is in I invent multi before this ' on brushless no control, the basis with the flat ripple DC generator (number of applying for a patent 201110312986.2) of reverse parallel connection diode circuit switching-over; On its stator, add special-purpose 3 phase windings of a cover alternative electric generation, and (two) altogether that realized the distortionless high specific energy of waveform, the peaceful ripple high voltage direct current of exportable interchange simultaneously are with generator (specific energy is higher during a pair of utmost point)! Undistorted because of having eliminated the bridge rectifier waveform, reduced interference to greatest extent near accurate electrical equipment.Also solved 5 generations opportunity of combat generating problem.
Excitation can adopt various ways.Considering in conjunction with the motor specific energy, because the DC generation coil can be multiturn, can send high-tension electricity, is again flat ripple, so it is the simplest to become the resistance self-excitation.
About specific energy relatively: though dual-purpose generator before this, especially 12 be in parallel rectification the fluctuation that makes reduce to some extent, all inequality for parallelly connected rectification, in office one wave amplitude (voltage, electric current) instantaneous, each phase.This battery that battery just as a plurality of different voltages is connected in parallel, voltage is high will charge to the low battery of voltage.And for polyphase ac winding parallel connection rectification, if there is not the existence of diode, that problem that just just waste and specific energy are low, but the high phase current of voltage will be through the low phase winding short circuit of voltage.According to having only Kirchhoff's law, this moment a phase output current that current potential is high.That is to say the external output current that forces down mutually this moment, waste is very big, specific energy is low.And partly adopted the direct current that shows by schematic diagram 2 just to make a world of difference at the DC generation winding of dual-purpose generator here around the drum-type winding, (can consult invention before this ' specification of flat wave height straightening current generator, the number of applying for a patent 201110312986.2).If the magnetomotive force that when neutral (void) line position switching-over of the physics of schematic diagram 2, because of the commutating coil short circuit current, produces with brush and resultant magnetic field direction fully on the contrary, cause demagnetize bigger, cause DC generator magnetomotive force (voltage) reduction.And be that brushless switching-over, commutating coil do not have short circuit current, the above-mentioned magnetomotive force situation that weakens does not take place here.
Also haveUsed direct current around drum-type here for can be thought of as single-phase alternator armature winding around the drum-type winding, in schematic diagram 2.The physics neutral line overlaps with normal neutral plane is instantaneous during current maxima.Want to remain such maximum, must make two neutral coincidence faces, two output line points just, transfer coil displacement one by one at random.Combine the diode reverse parallel circuits to accomplish (still consulting the number of applying for a patent 201110312986.2 specifications) around the drum-type winding.As long as commutating coil has electromotive force, no matter have or not lagging current, will be connected by electric potential of branch, and through its seek from be in maximum potential end line and string on the physics neutral line on this end line the rectifier diode derived current and realized that the flat wave height of brushless no control presses the output of (multiturn) direct current.And the reverse potential of having inducted from these coils between brush to the physics neutral line when not had to have the brush DC generator is to the counteracting of output potential; And keep the basic ripple disable of electromotive force maximum, efficient also is higher than three-phase synchronous generator during simple DC generation.The specific energy of this invention thus " the distortionless high specific energy of waveform is handed over straight (flat ripple) to be total to (two) and used generator " is much higher than all before this DC-AC two-use generators!
