Such as the circuit theory diagrams of voltage source circuit on the basis of Fig. 2, stabilivolt VD1, audion Q1 and the big electricity of resistance R1 composition
The mu balanced circuit of stream, make the voltage difference between VCC and Q1 emitter stage stable 5.6V(VCC-VREF=6.2V 0.6V=
5.6V), this is multi resonant oscillating circuit below and voltage comparison resistance provides stable reference voltage source.
Such as the circuit theory diagrams of overvoltage crowbar that Fig. 3 is output pipe, power output tube uses high performance reaching
Islington pipe, resistance to high back-pressure and big electric current.Meanwhile, the overvoltage crowbar using R21, R22 and D4 composition limits power tube Q9 two
The high back-pressure of end.It is as follows: R21 and R22 forms potential-divider network, when the voltage difference on R22 more than 51+0.7=51.7V(because of
Pressure drop for D4 is 51V) time, power tube Q9 turns on, that is to say that the primary coil of ignition coil turns on rapidly, and electric current is let out rapidly
Putting, backward voltage rapidly disappears.Now, corresponding on power tube backward voltage is: 51.7 * (R21+R22)/R22=
334.3(V).

The output pin of humorous oscillating circuit, the time (corresponding to the turn-off time of power tube) of its high level, by C3 and R6 decision, is one
Individual definite value.Approximate 0.7*C3 * R6.Its low level time (correspond to the ON time of power tube, namely ignition coil
The charging interval of primary coil) it not fixed value, its maximum is determined by C4 and R9, but in real work, leading of power tube
The logical time is also subject to the comparator being made up of Q4 and Q5 to control, namely by flowing through the electric current control of the primary coil of ignition coil
System.When electric current reaches the restriction electric current Ip set, Q5 ends, and Q4 turns on, and the base voltage of Q2 declines, and Q2 quickly reaches saturated
State.Q2 colelctor electrode output high level, makes Q7 end, thus causes power tube Q9 to end.Another one aspect, Q2 turns on it
After, Q3 ends rapidly, starts a new cut-off charging cycle process.
The potential-divider network that the threshold voltage of Q4 and Q5 composition comparator is made up of R10 and R12, R13 forms.According to schematic diagram
In numerical value, the pressure drop at R10 two ends is 0.6V, say, that when the pressure drop of current-limiting resistance R2 is more than 0.6V, the colelctor electrode of Q4
By output low level signal (relative to quiescent voltage value), causing Q2 to turn on rapidly, Q7, Q9 end rapidly.If relating to current limliting
Resistance is 160 milliohms, corresponding restriction electric current Ip=0.6/0.16=3.75A.
