The input of rectifying circuit 10 is AC power AC, can output obtain one direct voltage+V that whole circuit uses is provided and once the rectified wave a(of the full-wave rectification of overdamping shown in Fig. 2-1), the variation of its phase place is identical with alternating current AC in principle.
The input of Schmidt trigger 20 is from the rectified wave a of above-mentioned rectifying circuit 10, can be set in that this rectified wave a rises or when dropping to a certain current potential, make its output b(shown in Fig. 2-2) become high potential (being designated hereinafter simply as " 1 ") or electronegative potential (being designated hereinafter simply as " 0 "), and output b current potential is called original trigger region T1 at this during for " 1 ", each original trigger region T1 is begun by super initial point b1 as seen from the figure, and terminating point b2 finally.
The input of single trigger delay device 30 is from the output b of above-mentioned Schmidt trigger 20, can send just like the output c shown in Fig. 2-3, purpose is to make the starting point of trigger range have modulability, obtain a new trigger region T2 who starts from starting point c1, terminates in terminating point c2 so can export c at this, wherein starting point c1 is later than the starting point b1 of original trigger region T1, terminating point c2 then with terminating point b2 in stopping with the time.
Predetermined pulse is counted generation unit 40 and is comprised a trigger 41, a pulse generator 42, a counter 43, at first be that output c with above-mentioned single trigger delay device 30 sends into trigger 41, so trigger 41 just makes pulse generator 42 work when starting point c1, and send the pulse train d(of a predetermined quantity shown in Fig. 2-4 in during new trigger region T2), wherein this pulse train d is set to 64 pulses that comprise pulse d1～d64 in the present embodiment; Its setting quantity is that 64 mode is: when one by one counter 43 is sent in the pulse that it produced by pulse generator 42, counter 43 is just up counted to binary bit one by one, when count number arrives 64, to make its six outputs 431 all become " 1 ", be admitted to one and door 44 because of this six output 431 this moment, therefore with the output e(of door 44 shown in Fig. 2-5) will become " 1 ", trigger 41 sum counters 43 will be restored simultaneously, and trigger 41 is in case restored, pulse generator 42 just stops to produce pulse, when the next starting point c1 of output c occurred, pulse generator 42 just recovered to send pulse again.
The input of address counting unit 50 is counted the pulse train d of generation unit from above-mentioned predetermined pulse, it has the output of 12 (BITS), wherein Q11 is a lowest order for highest order Q0, so the changing value between the Q11 to Q0 can be by 000000000000 to 111111111111, if being reduced to hexadecimal represents, be 000-FFF.
Memory cell 60 can be by ROM, the EPROM of general use ... or the like design, be designed to have 12 address wire A11～A0 at this, highest order is A11, lowest order A0, that is the total 4K byte (BYTES) of its memory capacity (1K=1024), and the addressing of each address wire input is each output from above-mentioned address counter 50, receives minimum two output line Q1, Q0 respectively with the highest two address wire A11, A10 when it connects, and A9～A0 then receives Q11～Q2 respectively; At this Q11, A10 are received its main cause of Q1, Q0 respectively, it is storage setting for convenient memory cell 60, because, when Q11～Q0 up counts up to FFF by 000, four storage portions that length is the 1K byte in this memory cell 60 of scan flow will successively be taken turns in regular turn, i.e. first storage portions 000～3FF(A11A10=00), second storage portions 400～7FF(A11A10=01), the 4th storage portions of the 3rd storage portions 800～BFF(A11A10=11), and the data content that at every turn scans the addressing gained is just sent by its data wire D7～D0; So among 64 pulse d1-d64 in above-mentioned single pulse train d scope, the time interval that these four storage portions are addressed respectively, to shown in Fig. 2-9, wherein each storage portions all can be addressed 16 times in a pulse train d as Fig. 2-6.
This decoder 70 has the decoding function of 2-4 line, and its input is taken from address wire A11, the A10 of above-mentioned memory cell 60, so the waveform of its Ausgang 1～f4 is same as Fig. 2-6 respectively to shown in Fig. 2-9.
This multi-position switch group 80 has four groups of 8 outputs 81～84, but the Ausgang 1～f4 of the above-mentioned decoder 70 of mat takes turns turntable driving, and the data wire D7～D0 of above-mentioned memory cell 60 can be exported in regular turn in turn on eight output lines respectively organizing output 81～84; And totally 32 output lines of each output 81～84 all can be controlled the trigger angle that triggers a thyratron 91 respectively, and then reaches the power control to each load 92; In principle, because of the power supply of each load 92 be from AC power AC in addition full-wave rectification get, therefore its phase place is identical with rectified wave a in the rectifying circuit, only the amplitude of the two varies in size, so the single rectified wave a of aforementioned usefulness is drawn each accompanying drawing by the time correspondence, in fact also can be corresponding with the power phase of load end.
More than be the explanation of the control device square frame circuit of these a plurality of thyratrons with different trigger angles, as follows as for its entire combination action specification:
At first, observe in address counting unit 50 preceding 64 countings (being that Q11～Q0 counts up to 000000111111 by 000000000000), the variation of each address wire A11～A0 and data wire D7～D0 in the memory cell 60 during each counting, as shown in Figure 3, because in preceding 64 countings, Q11～Q6 remains " 0 ", promptly the address wire A9 of memory cell 60～A4 is " 0 " entirely, therefore for asking simple and clear, A9～A4 is not shown in figure; And 8 bit data of data wire D7～D0 gained in the memory cell 60, can design in advance and write in the memory cell 60, addressing each time just can obtain predefined 8 bit data, and as seen from the figure only when pulse d1, d7, d34, d48, can send effective triggering; Variation with each state is described as follows one by one again:
(1) when pulse d1: because of memory cell 60 is addressed at first storage portions, D7=1 only in the data wire of obtaining, again because of A11A10=00, so the Ausgang 1 of decoder 70 will drive multi-position switch group 80, and make data wire D7～D0 send from output 81, so the 8th line of output 81 triggers the thyratron 91 of its control, and makes this thyratron 91 conductings.
(2) when pulse d7: because of memory cell 60 is addressed at the 3rd storage portions, D3=1 only in the data wire of obtaining, again because of A11A10=10, so the Ausgang 3 of decoder 70 will drive multi-position switch group 80, and make data wire D7～D0 send from output 83, so the 4th line of output 83 triggers the thyratron 91 of its control, and makes this thyratron 91 conductings.
(3) when pulse d34: because of memory cell 60 is addressed at second storage portions, D0=1 only in the data wire of obtaining, again because of A11A10=01, so the Ausgang 2 of decoder 70 will drive multi-position switch group 80, and make data wire D7～D0 send from output 82, so first line of output 82 triggers the thyratron 91 of its control, and makes this thyratron 91 conductings.
(4) when pulse d48: because of memory cell 60 is addressed at the 4th storage portions, D1=1 only in the data wire of obtaining, again because of A11A10=11, so the Ausgang 4 of decoder 70 will drive multi-position switch group 80, and make data wire D7～D0 send from output 84, so first line of output 84 triggers the thyratron 91 of its control, and makes this thyratron 91 conductings.
More than be in address counting unit 50 preceding 64 gate times, the accessible trigger angle state of a control of control device of these a plurality of thyratrons with different trigger angles, again in per 64 gate times, each thyratron 91 that triggered by output 81～84 all has the chance that is triggered 16 times, whether be triggered as for each thyratron 91, the data that write in advance on memory cell 60 (D7～D0) decide then, yet, though each thyratron 91 has the chance that is triggered 16 times, but have only primary triggering really effective, because of thyratron 91 be at AC power source of sine wave each half wave cycles conducting in the time (no matter its whether by full-wave rectification all with), as long as just can keep conducting once triggering, till this half wave cycles finishes (this characteristic is the general characteristic of such circuit element); And the conducting situation (four thyratrons 91 have different trigger angle) of four thyratrons 91 when different time is subjected to triggering that be above-mentioned state 1 to the state 4 shown in Figure 4, wherein each oblique line part zone of being triggered conducting for thyratron 91.
In the foregoing description, each thyratron 91 is to be example with silicon controlled rectifier (SCR), so the power supply of each load 92 end must be earlier through over commutation, but each thyratron 91 is if adopt two-way thyratron (TRIAC), and then the power supply of load 92 ends can directly be sent into AC power; And, though each thyratron 91 only needs once to trigger and gets final product conducting in every half period of sine wave, but also can make continuous several times if necessary in half wave cycles triggers, as shown in Figure 5, it is the data output of gained in 64 addressing of another time period, 16 bytes that first storage portions is addressed and obtains wherein only are shown, and as seen from the figure, D7 is all " 1 " in 16 times addressing, all the other D6～D0 also send " 1 " more than once, so multi-position switch group 80 outputs 81 each line 811～818 also all trigger its thyratron of controlling 91 more than once, and the conducting state schematic diagram that is these eight thyratrons that triggered shown in Figure 6; This kind continuous several times triggering mode does not more need ohmic load (as bulb), but then comparatively needs for the control of inductive load (as motor), because this mode can be improved the discontinuous shortcoming of electric current possibility.
In addition in the present embodiment, the capacity of memory cell 60 has the 4K byte, that is address counting unit 50 to count up to 111111111111 by 000000000000 be a cycle period, so control device of these a plurality of thyratrons with different trigger angles, can organize rich variation of trigger electrode that thyratron 91 is done to each, not only can select to trigger wherein one group of output 81～84, more can do to trigger respectively each eight line organizing output.
When enlarging as if the capacity with address counting unit 50 and memory cell 60, its cycle period will be elongated thereupon, and this only is the equivalent structure variation of present embodiment, pardons not superfluous stating.
Take a broad view of above-mentioned, structure of the present invention, feature can provide a kind of control device of a plurality of thyratrons with different trigger angles really, but the setting in advance of its mat, and reach the sequence variation of controlling each trigger angle of load on several thyratrons simultaneously respectively, reached the purpose of invention really.
