Gate control circuit and predetermined voltage circuit working process are in Fig. 5 circuit:
As external control circuit F 011Output terminal is a noble potential, passes through R 11Make C 8Last voltage becomes noble potential, then F 5Output terminal is an electronegative potential, F 6Output terminal is a noble potential, with F 5The F that output terminal joins 12An input end also become electronegative potential, work as F 6The F that output terminal joins 14Input end becomes noble potential, satisfies left passage gating condition.Circuit working is when the ratio conducting state, and passage vibration and transfer process are: work as C 6Last voltage is high level, F 3Output terminal is a low level, F 12Two input ends are electronegative potential, and output terminal also becomes electronegative potential, C 6On electric charge pass through R 16, W 2Mid point, A end, D 7To F 12The output terminal discharge, meanwhile, F 14An input end is a noble potential, and another is an electronegative potential, and then output terminal is an electronegative potential, D 9Oppositely end.Work as C 6Power on to depress and drop to lower limit triggering level V 0［ 1-(R 12+ R 13)/R 13/ 2 ］ time, F 3Output terminal becomes noble potential, then F 14Two input ends are noble potential, and then output terminal also becomes noble potential, and then electric current is from F 14Output terminal passes through D 9, W 2B end, mid point, R 16To C 6Charging.Meanwhile, F 12An input end is a noble potential, and another is an electronegative potential, F 12Output terminal is a noble potential, D 7Oppositely end.Work as C 6Last level rises to upper limit triggering level ［ (R 12+ R 13)/R 13V 0/ 2 o'clock F 3Output terminal becomes electronegative potential again ... vibrate so repeatedly.
When left passage gating, right passage F 13Two input ends do not have the chance that becomes electronegative potential simultaneously, and then output terminal keeps noble potential, D always 8Oppositely end; F 15Two input ends do not become the chance of noble potential simultaneously, and output terminal keeps electronegative potential, D always 10Oppositely end, so right gate blocking.
When external control circuit makes C 8Last voltage becomes electronegative potential, F 5Output terminal becomes noble potential, F 6Output terminal is the right passage gating of electronegative potential, works as C 6Last level is a noble potential, F 3Output terminal is an electronegative potential, F 13Two input ends are electronegative potential, and then output terminal is an electronegative potential, C 6Pass through R 16, W 3Mid point, C end, D 8To F 13The output terminal discharge; Meanwhile, F 15Two input ends can not be noble potential simultaneously, and then output terminal is an electronegative potential, D 10Oppositely end; Work as C 6Last level is an electronegative potential, F 3Output terminal is a noble potential, F 13Two input ends can not be electronegative potential simultaneously, and then output terminal is a noble potential, D 8Oppositely end.F meanwhile 15Two input ends are noble potential, and then output terminal is a noble potential, and electric current is from F 15Output terminal passes through D 10, W 3D end, mid point, R 16To C 6Charging.
When right passage gating, F 12Two input ends do not become the electronegative potential chance simultaneously, and output terminal keeps noble potential, D always 7Oppositely end F 14Two input ends do not become the chance of noble potential simultaneously, and output terminal keeps electronegative potential, D always 9Oppositely end left gate blocking.
The predetermined voltage circuit provides the course of work of voltage signal to be to executive circuit: work as F 3Output terminal is a noble potential, F 4Output terminal provides voltage signal to executive circuit during for electronegative potential.During left side passage gating, potentiometer W 2Mid point is many more to A end sliding distance, and dutycycle is big more, to capacitor C 6Duration of charging is short more, and discharge time is long more, and the output voltage numerical value that provides to executive circuit is high more; Otherwise, potentiometer W 2Many more to B end sliding distance by mid point, dutycycle is more little, and the output voltage numerical value that provides to executive circuit is low more.The right passage course of work is identical with left passage.
Phase modulation ratio conducting transfer process is: work as K 2-1, K 2-2Disconnect, circuit working is in the phase modulation state, and synchronizing signal is from BG 3Collector passes through R 4To F 4Input end, behind zero crossing, BG 3Current collection is noble potential very, then F 1Output terminal is an electronegative potential, D 4Oppositely end; When zero crossing, BG 3Current collection is electronegative potential very, F 1Output terminal is a noble potential, D 4Forward conduction, F 1Output terminal passes through D 4To C 6Charging makes circuit become the phase shift state from free-running operation, because K 2-2Disconnect shift capacitor equivalence C 6, C 7Series connection, the requirement when just in time satisfying phase modulation work.
Work as K 2-1, K 2-2Closed circuit works in the ratio conducting state, enters F 1The synchronous voltage signal of input end passes through K 2-1To power positive end bypass, then F 1Output terminal keeps electronegative potential, D always 4Oppositely end, circuit working is in free-running operation, because K 2-2Closure, oscillating capacitance becomes C 8, satisfy the requirement of circuit.
The phase modulation course of work is as follows: circuit working is in left passage, when zero crossing, and F 1Output terminal becomes noble potential, and electric current is from F 1Output terminal passes through D 4With C 6Be charged to supply voltage, behind the zero crossing, F 1Output terminal becomes electronegative potential, D 4Oppositely end, at this moment F 12Output terminal is an electronegative potential, C 6On electric charge pass through R 16, W 2Mid point, A end, D 7To F 12C is worked as in the output terminal discharge 6Power on and depress when dropping to the lower limit triggering level F 3Output terminal becomes noble potential, F 4Output terminal provides trigger voltage signal for electronegative potential to executive circuit.Work as W 2Mid point slides to A end, then C more 6The velocity of discharge is fast more, F 4It is fast more that output terminal becomes the electronegative potential time, and phase shift is more little, and the output voltage numerical value that provides to executive circuit is high more, works as W 2Slide to B end, then C more by mid point 6The velocity of discharge is slow more, F 4It is slow more that output terminal becomes the electronegative potential time, and phase shift is big more, and the output voltage numerical value that provides to executive circuit is low more.
In like manner, during right passage gating, potentiometer W 3Many more by mid point to C end sliding distance, provide output voltage numerical value high more to executive circuit, W 3Many more to D end sliding distance by mid point, the voltage value that provides to executive circuit is low more.
Synchronizing pulse waveform transformation process is: after the power-on, sinusoidal voltage passes through R 1To BG 1, BG 2Base stage, positive half cycle BG 1Conducting, electric current passes through R from power positive end 2To BG 1The collection emitter-base bandgap grading is gone into ground, negative half period BG 2Conducting, electric current passes through R from power positive end 2To BG 2Emitter-base bandgap grading, collector are gone into ground, BG 3No base flow and end BG 3Current collection is noble potential very.BG during zero crossing 1, BG 2End, electric current passes through R from power positive end 2To BG 3Base stage is gone into ground, BG 3Conducting is electronegative potential, thereby realizes being transformed into from sine wave the waveform transformation process of burst pulse.
The course of work of zero cross fired during the ratio conducting: work as F 4Output terminal is a noble potential, circuit no-output, D 3Forward conduction flows through R 5Synchronizing signal pass through D 8To F 4The output terminal bypass, F 2Output terminal is an electronegative potential always, D 13Oppositely end.Electric current passes through R from the ground end 22To C 11Charging, F 9Input end becomes electronegative potential, and output terminal is a noble potential, D 6Forward conduction.Work as F 4Output terminal becomes electronegative potential suddenly, and then electric current is from F 4Output terminal passes through R 17, D 6To F 9The output terminal bypass, circuit triggerless voltage signal output, only when zero crossing, F 2Output terminal passes through D 13With C 11Be charged to noble potential, F 9After output terminal became electronegative potential, trigger pulse just was added to BG 4Base stage is to guarantee F 4Output terminal provides the zero cross fired signal to executive circuit in electronegative potential and noble potential alternation procedure.
Finishing of trigger pulse limit for width process: the limit for width of trigger pulse adopts RC chronotron, capacitor C 11, resistance R 22, R 18, F 9The width of the threshold voltage decision trigger pulse of input end.For example when phase modulation is worked, at zero crossing place, C 11By F 2Output terminal passes through D 13Discharge once F 9Output terminal becomes electronegative potential, D 6Oppositely end, at F 4Output terminal does not also become during the electronegative potential, and electric current passes through R from the ground end 22To C 11F is worked as in charging 4When output terminal became electronegative potential, electric current was again from D 5, R 18, another loop is to C 11C is worked as in charging 11Power on to depress and drop to when being lower than 1/2 supply voltage F 9Output terminal becomes noble potential, will flow through R 17Electric current pass through D 6, F 9The limit for width process is finished in the output terminal bypass, works as R 18, R 22, C 11The big more then time-delay of time constant is long more, and then Shu Chu pulse is wide more.RC chronotron time constant also will be subjected to F 4The influence of output terminal duty is for example as the more little F of phase shifting angle 4It is fast more that output terminal becomes the electronegative potential time, and it is wide more then to export pulse, when phase shifting angle big more, F 4It is slow more that output terminal becomes the electronegative potential time, and it is narrow more then to export pulse.
Embodiment: the effect of external control circuit is that the responsive control of timing voltage is compared, and removes to control gate control circuit by output terminal then.
External control circuit is by amplifier F 011Coaxial doubly-linked potentiometer R 7, R 10, plug-type potentiometer W 1And K switch 1-1, resistance R 8, R 9, R 11, capacitor C 5, C 8, socket CZ 1, CZ 2Form.
