Make of low cost, a phase winding, which does not work not, in the middle influences the normal work of other phase windings, and fault-tolerance is strong, has wide answer
Use foreground.
Switched reluctance machines are generally symmetrically distributed in by multiple phase windings in stator salient poles, and each phase winding is divided into mostly again
Two branch windings are symmetrically distributed in different stator salient poles, are determined according to the relative position of salient pole between rotor and groove specific
The phase winding of energization, it is different as the on-position of generator and motor rule, but identical is each phase winding according to relatively
Rotor position information timesharing work respectively；When as generator operation, excitation and power generation are generally divided into when work per phase winding
In two big stages, be powered excitation first before and after winding inductance maximum region, and excitation stage motor phase windings absorb external excitation electricity

The magnetic energy stored in group is converted into electric energy output, and electric current is down to zero completion work when into winding inductance Minimum Area；As
When electric motor operation, per phase winding, the main body of work is the excitation stage, when winding inductance Minimum Area or inductance rise beginning
Energization excitation, the front and back shutdown excitation of winding inductance maximum region to be entered are completed work, are provided after excitation when necessary continuous
Road is flowed back to discharge the remaining magnetic energy in winding.
The operation control that the excitation of switched reluctance machines, power generation will surround the translation circuit for connecting its winding realizes do not have
There is winding translation circuit, the operation of switched reluctance machines is not just known where to begin, so converter is significant.
Since the branch winding that same phase winding as mentioned above is often divided into two or more even numbers is symmetrical with different salient stators
Distribution on extremely, based on the needs to enhanced excitation performance, industry is existing for example to increase the pattern of two branch winding parallels
Add excitation voltage twice (opposite conventional serial pattern), the excitation stage is in parallel, power generating stage series connection, but, this pattern in addition to
Single twice of excitation of reinforcing is outer without other advantages, still can be along exporting all the way when power generating stage exports.
When being run as switch reluctance generator, low-voltage DC is directly exported, is generally required by directly handing over straight DC/DC
Exported again after converter to load or it is grid-connected, so as can design can boost and save portion link simple DC/DC transformation
Device structure certainly will be then development trend and important advance.
When under complicated switch reluctance generator operating condition, such as variable-speed wind-power field, MPPT and maximum generation effect
Rate control must face, in order to promote its performance, often it is contemplated that by change excitation voltage and generating voltage, and power
It is the basis that higher performance obtains if converter itself has the hardware condition of pressure-variable.
Same set of power inverter, if indiscriminate can be used when as generator and motor running, gesture
It must can improve the adaptability and cost performance of system.
No matter switch reluctance generator or motor, accumulator is often needed, also tend to need manually to participate in
Accumulator charges or replaces accumulator, increases manual maintenance workload, reduces intelligent level, as can carrying as needed
Self-charging function, then such power inverter certainly will increase the intelligent level of system.

(3) secondary side winding the number of turns of two transformers of rectifying output circuit is more than first side winding the number of turns, in addition
Rectifying output circuit outlet side is that rectification is connected in series with after the output of two transformers, to realize that two-stage is boosted, is realized simultaneously
It is isolated, saves the three zones such as inverter, and be not necessarily to switching device in this, is not necessarily to the participation of controller, simplifies structure
With control complexity, reliability is improved.
(4) excitation can close after pipe is closed through eighteenmo and charge a battery, be greatly saved people with charging circuit
Work improves intelligent level；When 19th switching tube is closed conducting, excitation electricity can be become by adjusting the 17th switching tube and realizing
Enhanced excitation can be achieved in pressure output naturally, meanwhile, the outlet side electric current of the excitation and charging circuit is in the 17th switching tube PWM
It is always continuous when control, is more advantageous to subsequent charging and the raising of excitation stability；In short, excitation and charging circuit,
It provides and becomes excitation voltage, Qiang Li, excitation, four big function of automatic charging, it is significant.
(5) when overlap coefficient rationally (be more than 0 be less than 0.5), when rated condition, two transformer input side electric currents alternatings are defeated
Enter uninterruptedly, it is efficient；Also, in response to the needs of system performance control, when non-specified, by controlling third switching tube/4th
The switching tube of the switching tube of switching tube, the 7th switching tube/the 8th, the 11st switching tube/the 12nd, the 15th switching tube/sixteenmo
The switch time of pipe is closed, it can be achieved that phase shift is adjusted, the generating voltage value of adjusting final 9th capacitor and the tenth capacitor-side is wrapped
Power is included, it is significant to greatly enhance controllability, the flexibility of system.
(6) since excitation and charging circuit export the adjustability of the wider range of excitation voltage and aforementioned generating voltage
Adjustability greatly enhances the adaptability of system, such as in complicated variable-speed wind-power field and High speed SRM fortune
Row field.
(7) it under structure and control methods of the invention, when as motor running, can all be applied in structure, no wave
Take, hardware will not be increased, control method is identical, when unique difference is the switch of excitation when being run as switched reluctance motor
Carve with difference as switch reluctance generator, and power generating stage when as generator is in this as stage of releasing and can be real
Existing energy regeneration.
