Description
Technical Field
The invention belongs to the technical field of generator control circuits, and particularly relates to a single-phase gasoline generator control circuit.
Background
The control circuit of the single-phase gasoline generator generally generates a sufficient high voltage at a proper rotation angle in each period during the operation of the generator, and the compressed high-temperature and high-pressure combustible mixture is ignited by spark plug flashovers of each cylinder to complete the work process.
In the prior art, as shown in fig. 1, a primary coil L5 (i.e., a magneto stator) of an ignition coil induces a set of electromotive force pulse waveforms (e.g., hand-cranking a magneto rotor); when the L5 induced electromotive force negative pulse front arrives, the C22 end discharges to become a negative level, so that after the L5 induced electromotive force positive pulse front arrives, the triode Q221 cannot be conducted before the triode Q223 due to the voltage division effect of the resistor R106 and the resistor R107, and after the triode Q223 is conducted, the triode Q192 and the triode Q222 are conducted. After the triode Q222 is conducted, the induced electromotive force induced by the primary coil L5 of the ignition coil forms loop conduction through the primary coil L5, the resistor R110 and the C, E pole of the triode Q222.
Then the voltage drop on the resistor R110 increases along with the increase of the current, when the voltage drop on the resistor R110 is larger than the voltage drop of the resistor C22 and exceeds 0.7V, the triode Q220 is conducted to charge the capacitor C22 (at this time, the circuit formed by connecting the triode Q220 and the capacitor C22 in series is equivalent to connecting a resistor in parallel with the resistor R106), the triode Q221 is cut off, the voltage on the capacitor C22 increases along with the rising of the pulse front, the voltage of the pole B of the triode Q220 is lower than the voltage on the capacitor C22 after the induced electromotive force reaches the pulse peak value, the triode Q220 is cut off (the electric quantity charged on the resistor C22 is released through the triodes Q220 and Q221), at this time, the voltage drop on the resistor R107 also increases to enable the triode Q221 to be conducted, so that the triodes Q223, Q192 and Q222 are cut off accordingly, at this time, the voltage on the primary coil L5 is self-induced by a voltage of hundreds of volts due to the abrupt current change, the voltage is boosted through the secondary coil L6, the voltage above 10KV is output on the secondary coil to the spark plug, and the mixture in the engine cylinder is ignited.
The ignition control circuit can provide high enough voltage to ignite the mixture in the cylinder of the engine through the spark plug when the engine needs to be ignited, so that the ignition combustion of the mixture in the cylinder of the gasoline engine is realized.
However, the discrete device scheme has simple structure and circuit and poor consistency and temperature characteristics. Because the BE junction voltage drop of the NPN tube is-2 mV/DEG C, if the normal-temperature current is 3A, the low temperature-30 ℃ can BE 3.3A, and the high temperature 85 ℃ is 2.7A. The control circuit of the single-phase gasoline engine generator is a discrete device scheme, and has poor reliability and high cost.

In this embodiment, the primary coil L1 of the ignition coil induces a set of electromotive force pulse waveforms, and the pulse voltage supplies power to the control unit through the R1 resistor, and when the pulse voltage rises from 0V to about 1.5V, the internal reference function module Vref slowly rises from 0V to 1.25V, and finally stabilizes at 1.25V.
The whole working principle of the circuit is divided into three states according to the voltage V1 on R6:
In the first state V1<200mV, I1 outputs a high level, Q1 outputs a low level, i.e., I3 outputs a constant low level, and I4 outputs a low level due to the negative terminal level Vref (1.25V), Q3 is not conductive, and I5 is not triggered. Therefore, in the first state, the circuit is in a protection state, and false triggering of I2 and I3 is prevented.
When V1 is less than or equal to 1.25V in the second state, I1 outputs low level, and Q1 is in a cut-off state. I2, I3 are in standby state, detect V1's withdrawal signal, when V1 changes from rising to falling, when the decline amplitude reaches about 15mV, I2, I3 function trigger, I3 output high level, Q2 switches on, trigger I5 for Q4 switches on, and output darlington pipe closes. The second state of the circuit corresponds to manual gasoline ignition, and because the rotation speed of the coil is low and the induced electromotive force on the induction coil is low during manual ignition, the voltage on V1 can not reach 1.25V, and therefore the peak current in the process of generating the induced electromotive force needs to be ignited.
When the voltage of V1 is always in the rising state and reaches 1.25V when the voltage of V1 is more than or equal to 1.25V in the third state, I1 and I3 are both in the output low level state, Q2 is in the off state, I4 starts to overturn, the output becomes high level, and Q3 is conducted. And triggering I5, conducting Q4, and closing an output Darlington pipe. The third state corresponds to an ignition state corresponding to 3000 turns of the coil rotating speed after the ignition of the gasoline igniter.
The output darlington tube composed of Q5 and Q6 is turned on when the pulse voltage reaches about 1.2V, and a voltage difference starts to be generated on the current detection resistor R6. When pulse voltage continues to rise, the output current of the output Darlington tube formed by Q5 and Q6 is larger and larger, namely the current flowing through R6 is continuously increased, when the voltage drop on R6 reaches 1.25V, an ignition signal is triggered, an internal comparator I4 acts, the I4 output drives the Q3 tube, the I5 triggers, the I5 output enables the Q4 to be conducted, and accordingly the voltage of the input end of the output Darlington tube is pulled down, and the effect of turning off the Darlington tube is achieved. The output Darlington pipe composed of Q5 and Q6 is suddenly turned off, so that the current on the primary coil L1 is suddenly changed to induce a voltage of hundreds of volts, the voltage is boosted through the secondary coil L2, and the voltage of more than 10KV is output to a spark plug through the secondary coil, so that the mixed gas in an engine cylinder is ignited.
In the process of rising the pulse voltage, the pressure difference on R6 can rise along with the rising of the pulse voltage, and when the pulse voltage reaches a peak value and the pressure difference on R6 does not reach 1.25V yet, the I2 and I3 peak ignition functions of the circuit are started. The I2 comparator performs a follower function, and the I2 output voltage Vt rises as the sampling terminal voltage (the voltage difference across R6) rises. When the voltage of the sampling end drops, the voltage of the Vt end is slower than the voltage of the sampling end due to the energy storage function of the C2 capacitor, so that the voltage of the sampling end is smaller than the voltage of the Vt end, when the voltage difference reaches 15mV, the I3 outputs a high level, so that the Q2 works until the I5 is triggered, and the Darlington tube is cut off. The comparator I1 is used as delay trigger, and when the voltage of the sampling end is smaller than 200mV, the Q1 is in a conducting state, so that the input signal of the Q2 is constantly low level. So that I5 is not triggered.
In one embodiment, r1=3kΩ, r2=100deg.kΩ, r3=20kΩ, r4=1kΩ, r5=500Ω, r6=0.6Ω. These parameters are just a specific example, and a person skilled in the art can adjust a part of resistance according to an actual experimental result, for example, the working current can be changed by adjusting R6, when the resistance is larger, the on current is small, and when the resistance is off, the induced voltage of L1 is too low to ignite; when the resistance value is smaller, the L1 induction voltage is too high in cut-off, and the device can be damaged.
In another embodiment, in the control unit, a zener diode DZ is further connected between the second pin and the fourth pin. In the embodiment, the voltage stabilizing tube is added, the rated voltage of the subsequent element is reduced, and the variable part of discrete devices is changed from external to internal.
Preferably, the third comparator I3 is a comparator with built-in offset voltage, that is, positive and negative channels in the I3 comparator are asymmetrically arranged, so that the offset voltage is artificially offset to be a predetermined voltage, and the offset voltage in the embodiment is 15mV, so that false triggering can be prevented when the Vt terminal voltage is reduced slower than the sampling terminal voltage due to the energy storage function of the C2 capacitor. The specific value of the offset voltage can be set through an actual experiment, and will not be described here again.
The control circuit of the single-phase gasoline generator adopts an integrated circuit chip to replace discrete elements in the prior art circuit, adopts a Darlington tube to bear high voltage, and is externally connected with only 2 resistors (R1 and R6). The working current can be changed by adjusting R6, when the resistance value is larger, the on current is small, and when the resistance value is cut off, the L1 induced voltage is too low to ignite; when the resistance value is smaller, the L1 induction voltage is too high in cut-off, and the device can be damaged. The voltage reference unit is adopted for peak protection, the peak current detection is more accurate, and the detection point does not change along with the temperature change.
It should be noted that, the resistance of the resistor is only one specific embodiment, and the specific data of the resistance of the resistor is not limited in the present application, and the voltage dividing effect needs to be satisfied.
The above examples illustrate only a few embodiments of the application, which are described in detail and are not to be construed as limiting the scope of the application. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the application, which are all within the scope of the application. Accordingly, the scope of protection of the present application is to be determined by the appended claims.
