Background technology
Compensating pulse electric generator is a kind of pulse power supply that utilizes inertia energy storage, utilizes electromagnetic induction and magnetic flux contraction principle to reduce the inductance of generator, makes it export the pulse current of amplitude.This generator energy collecting storage, energy converting between mechanical and pulse shaping have energy density and power density height, stability and reliability advantages of higher in one.Compensating pulse electric generator can be divided three classes according to compensation way: passive, select passive and initiatively.The Active Compensation mode needs the outside electric current that affords redress; Passive compensating form utilizes the aluminium alloy compensating cylinder that armature winding is realized full compensation; This moment, the armature winding inductance kept steady state value, the output sinusoidal current waveform, and these two types of compensation ways are difficult to the modulation ratio of power; Select passive compensated pulsed alternator then to utilize the compensation winding to realize the selecting type compensation, the armature winding inductance is done sinusoidal variations.
" a kind of compensating pulse electric generator " (Liu Kefu etc., CN 1253406A, on May 17th, 2000 are openly) introduced compensating pulse electric generator, but do not propose effective power modulation method.Existing passive compensated pulsed alternator compared with techniques is in selecting passive compensation way to have following defective: the pulse power modulator approach is single, can only realize the modulation of power output through increasing the armature winding number of phases or CSET; The power-supply system volume and weight is big, and CSET and increase winding will inevitably increase the volume and the quality of power-supply system, the decrease of power density and power density; Application is limited, because the power modulation difficulty is difficult to adjust according to the variation of loading demand, can only be applied to when really using in the specific field of part.
Summary of the invention
The objective of the invention is to overcome the shortcoming of above-mentioned prior art, a kind of selection passive compensated pulsed alternator is provided, it has improved the output performance of compensating pulse electric generator, has expanded application.
The objective of the invention is to solve through following technical scheme:
This selection passive compensated pulsed alternator is made up of rotating shaft, rotor, excitation winding, self-closing compensation winding, armature winding, non-groove stator, casing, front and rear cover and brush and collector ring; Said excitation winding is installed in and realizes rotating excitation in the rotor; Said self-closing compensation winding is fixed on the rotor, and armature winding is fixed on the inner surface of non-groove stator; Stator is fixed in interior; Front and rear cover is installed in the casing two ends; Rotor and end cap axle center are passed in rotating shaft, play a supporting role; In roller end brush and collector ring are installed simultaneously, the exciting current that outside exciter provides is introduced excitation winding.
Above-mentioned rotor is opened in the axial groove on the rotor outer peripheral face for symmetry.
Above-mentioned self-closing compensation winding is fixed on the outer surface of rotor through epoxy casting.
Selection passive compensated pulsed alternator of the present invention adopts outside constant-current source to realize excitation, in the generator steady state operation, according to electromagnetic induction principle; In air gap armature winding, induce the unloaded electromotive force of sinusoidal variations, when armature winding is connected load, flow through pulse current in the armature winding; Pulse current goes out the magnetic field of variation at the generator internal motivation; The self-closing compensation winding that is fixed in rotor outer surface must be passed in this magnetic field, when compensating the flux change of winding encirclement, just goes out electric current to offset the variation of magnetic flux at the winding internal induction; The eddy current that the armature winding internal induction goes out can be compressed in the magnetic field that the armature winding electric current produces in the air gap between stator and rotor; Thereby effectively increase magnetic circuit, improve magnetic resistance, finally reduce the inductance of armature winding.Because the compensation winding is installed in rotor outer surface; Compensation effect to armature winding is done sinusoidal variations with the rotation of rotor; When planes that armature winding and compensation winding surround separately, compensation effect is best, and compensation effect was the poorest when two planes were vertical each other.Therefore, select structure that passive compensated pulsed alternator can be through control compensation winding and armature winding self and cooperatively interact the purpose of realization power modulation.

Embodiment
Below in conjunction with accompanying drawing the present invention is done and to describe in further detail:
Referring to Fig. 1 and Fig. 2, selection passive compensated pulsed alternator of the present invention is made up of rotating shaft 7, rotor 6, excitation winding 5, self-closing compensation winding 4, armature winding 3, non-groove stator 2, casing 1, front and rear cover and brush and collector ring.Excitation winding 5 is installed in and realizes rotating excitation in the rotor, and rotor is opened in the axial groove on rotor 7 outer peripheral faces for symmetry.Self-closing compensation winding 4 is fixed on the outer surface of rotor 6 through epoxy casting.Armature winding 3 is fixed on the inner surface of non-groove stator 2; Stator 2 is fixed in casing 1 inside, and front and rear cover is installed in casing 1 two ends, and rotor 6 and end cap axle center are passed in rotating shaft 7, play a supporting role; At rotating shaft 7 ends brush and collector ring are installed simultaneously, the exciting current that outside exciter provides is introduced excitation winding.
Selection passive compensated pulsed alternator of the present invention rotating shaft 7 is connected with external prime mover, and the exciting current of excitation winding 5 is supplied with by outside exciter.Prime mover drives rotating shaft 7 makes rotor 6, excitation winding 5,4 rotations of compensation winding until rated speed, flows through the constant excitation megnet electric current in the excitation winding 5, therefore can in armature winding 3, induce unloaded electromotive force, and the mode of connection of armature winding 3 is shown in accompanying drawing 4.In conjunction with accompanying drawing 3; Exchange the unloaded electromotive force that voltage source V 0 replaces armature winding 3 to induce with ideal; When the output of armature winding 3 and nonlinear resistance load R2 connected, the desirable 0 couple of ohmic load R2 of voltage source V that exchanges carried out pulsed discharge, and flow through pulse current in the armature winding 3 this moment; Two groups of compensation windings 4 replace with the closed-loop path that resistance R3, R4 and armature winding self-induction L2, L3 constitute respectively, and the self-induction L1 of armature winding 3 and resistance R 1 are also contained in the circuit; Because two groups of compensation windings 4 are with rotor 6 rotation, so mutual inductance M2, M3 between compensation winding 4 and the armature winding 3 do sinusoidal variations, but between the group of two groups of compensation windings 4 mutual inductance M1 only with group between phase difference γ relevant.The pulse current that flows through armature supply 3 induces eddy current through acting in the compensation winding 4 of mutual inductance M2, M3; This eddy current is oppositely offset the magnetic field that armature supply produces again; When ideal interchange voltage source V 0 certain amplitude constantly is low; But this moment, compensation effect was good, so the inductance of armature winding 3 is lower, caused the current amplitude meeting of output higher; When ideal voltage source V0 amplitude constantly is higher, but the compensation effect of compensation winding 4 is relatively poor, and the inductance of armature winding 3 is higher, and this moment, the current amplitude of output on the contrary can be low.This shows, regulate the compensation effect of 4 pairs of armature winding 3 of compensation winding and can regulate electric current and power.Phase difference is δ between compensation winding 4 and the excitation winding 5, and two groups of phase differences that compensate between the winding 4 are γ.δ can regulate the compensation effect that compensates 4 pairs of armature winding 3 of winding to a certain extent through the adjustment angle, realizes the modulating action to the output pulse power; In addition, the assembly angle γ that changes compensation winding 4 can realize the compensation effect that 4 pairs of armature winding of two groups of compensation windings 3 are different, adjusts the same modulating pulse power of this angle.Therefore, the action rule according to angle δ and γ paired pulses power carries out fit adjustment, can realize selecting the flexible modulation of passive compensated pulsed alternator power output.
