Abstract
A kind of peak transform that is used for the triggering of controllable silicon simultaneous phase-shifting, former limit winding technique is provided with magnetic shunt between the closed loop of main magnetic circuit on the closed main magnetic circuit in the thick cross section that magnetic material constitutes, signal winding and phase shift winding are set on the magnetic shunt.Be characterized in that former limit winding can directly insert power frequency supply and use, volume is little, and energy consumption is low, and the environment stray EM field is had good shielding action, can be widely used in the silicon controlled control circuit.
Description
The present invention is a kind of control triggering silicon controlled peak transform that is used for.
According to Shen Shangxian chief editor " industrial electronics ", People's Education Publishing House, in April, 1964 version, the P188 page or leaf.
Soviet Union A.. г openuK work Shen Shangxian etc. translates " industrial electronics " Science and Technology of Shanghai publishing house version in May nineteen sixty, P205 page or leaf.
The structure of the summit transformation of being narrated in two pieces of works is as figure one.Adopt П type thick cross section iron core (1) to put former limit winding (2) and phase shift winding (3) thereon, with permalloy (5) place П sections core openend to be the shape of the mouth as one speaks and in its periphery by putting signal winding (4).One of the peak transform of this structure is venerated can get a pair of positive and negative summit pulse.When its former limit winding directly inserts power frequency supply, former limit winding is burnt because of exciting curent is excessive because when permalloy very fast saturated after, magnetic field increases to the space magnetic resistance that scatters, the induced potential drop-out current increases and is caused in the winding of former limit.If in order to reduce the electric current in the winding of former limit, can regard transformer as the inductance of an open magnetic circuit, the increase inductance value could reduce the electric current in the winding of former limit, and what therefore bring is that no-load loss increases, and power factor (PF) descends, and is bulky.The phase shift winding will obtain certain phase shifting angle by putting on the iron core of thick cross section, is example with the direct current phase shift: very big number of ampere turns must be arranged, the corresponding configuration high-power DC power supply, energy consumption is very big, and whole magnetic circuit direct current composition increases, and makes induced potential decline and increase electric current in the winding of former limit again.Have the structure of peak transform in a word now, it is big to exist energy consumption, and volume is big, the cost height, and for adopting all electronic circuits control triggering silicon controlled technology at present in a large number, obviously more harm than good, on the verge of being replaced, do not setting foot in a lot of works.
The objective of the invention is to:
In order to overcome above-mentioned difficulties, provide a kind of improved peak transform.
The scheme of peak transform of the present invention is to manage to set up a main flux by the power frequency supply intake, sets up some minutes magnetic circuits that it is reached capacity between main magnetic circuit and obtains some summit pulse signals.Its specific design is: constitute the closed main magnetic circuit in thick cross section with magnetic material, with magnetic material the magnetic shunt that one or more have thin section is set between the closed loop of main magnetic circuit.The former limit of coiling winding is provided with signal winding and phase shift winding on each magnetic shunt on main magnetic circuit.Here said thick cross section and thin section are comparatively speaking, and promptly the cross section of main magnetic circuit should be far longer than the cross section of magnetic shunt, and this is that the pulse of formation summit is necessary.
Peak transform of the present invention has following advantage:
1. Shu Chu signal pulse and phase shift winding and former limit winding mutual insulating are isolated, and former limit winding can directly insert power frequency supply.
2. main magnetic circuit is closed fully, and magnetic resistance is little, so no-load loss is little, and volume is little.
3. signal winding and phase shift winding are set in place on the branch magnetic circuit between the main magnetic circuit closed loop, constitute " shell-type " structure, and the interference of environment stray EM field is had the decay shielding action.
4. transformer is provided with a magnetic shunt and comprises that three windings just can be finished the low simultaneous phase-shifting that triggers power controlled silicon is triggered, this is in all electronic circuit, usually finish, thereby can simplify circuit structure by sync signal, phase shift, trigger impulse three part circuit.
5. a transformer is provided with more than one magnetic shunt and corresponding signal winding and phase shift winding, just can satisfy the needs of multichannel complete machine.
6. this transformer does not need to add in addition quarantine measures and just can control triggering to controllable silicon for the low controllable silicon that triggers power of high-tension circuit, and triggering power controlled silicon for height only need increase power amplifier.And pulse can be arrived greater than 10 ° in broadening.
7. not only volume is little for this transformer, and simple in structure firm, and cost is low, has wide practical value.
Peak transform of the present invention can be widely used in the silicon controlled simultaneous phase-shifting and trigger for example acquisition of the power supply peak value sync signal in the YAG repetition-rate laser power supply.The application of aspects such as single-phase and three-phase controlled rectifier circuit.
Sets forth in detail embodiments of the invention in conjunction with the accompanying drawings.
Figure one is the structure chart of existing peak transform.
The structure of peak transform of the present invention is shown in figure two.
(6) are closed main magnetic circuit among the figure, and its shape can be different shape, as rectangular frame, and square frame, garden rings etc. have the thick cross section that the electro permanent magnetic material constitutes, and its cross sectional shape also can be different shape, as rectangle, square, garden shape etc.Can adopt CD type series silicon steel core for being fit to batch process.The former limit of coiling winding (7) on closed main magnetic circuit.The magnetic shunt (8) of thin section is set between the closed loop of main magnetic circuit, coiling signal winding (9) and phase shift winding (10) on magnetic shunt, the cross sectional shape of magnetic shunt also can be different shape, and as square, garden shape or rectangle etc. adopt the permalloy sheet usually.The sectional area of main magnetic circuit should be far longer than the sectional area of magnetic shunt.While coiling signal winding and phase shift winding on magnetic shunt, it is provided with said signal winding and phase shift winding variety of way can be arranged, preferably phase shift winding (10) is tightly enclosed outside signal winding (9), with anti-interference and the minimizing power frequency modulating signal amplitude that increases the signal winding.A peak transform also can be provided with more than one magnetic shunt, is another magnetic shunt and corresponding signal winding and phase shift winding as what dotted line among the figure was represented, satisfies the needs of complete machine to the multiplex pulse signal to adapt to a transformer.Another feature of peak transform of the present invention be said magnetic shunt and on signal winding and the surrounding of phase shift winding by put the main magnetic circuit that is closed as far as possible, form " shell-type " shielding construction.
The pulse signal that this transformer is exported can directly be controlled without the electronics power amplifier and trigger 3CT-20 type controllable silicon, when the size and Orientation that changes the direct current dephased current can obtain 0～60 ° phase shifting angle, the excursion of its direct current dephased current is ± 0～300 milliamperes.
