Though the present invention allows various modifications and alternative form, shown specific embodiment by the example mode in the accompanying drawings, and will here be described in detail.Yet, should be appreciated that the present invention is not limited to particular forms disclosed.On the contrary, the present invention falls into all modifications, the equivalence of the spirit and scope of the present invention that limit as claims with covering and substitutes.
The specific embodiment
The present invention the most general aspect, it relates to the electronic igniting circuit that is used for oil or gas burner.The invention particularly relates to the high voltagehigh frequency firing circuit, it comprises power supply, noise inhibiting wave filter, resonator, current control circuit, reset diode and the high frequency transformer on the magnetic core.
With reference now to Fig. 1,, noise suppression circuit is made up of element L1, R1, C3, C4 and C5.Power supply is made up of half-wave rectifying circuit D1 and D2.This power supply is with half-wave voltage and the follow-up oscillator of electric current supply.Electronic igniting circuit also comprises the oscillating circuit that is limited by element R2, R3, DZ1, TR1, C1 and transformer T1.This transformer and feedback winding are connected to the grid of TR1, to provide oscillator required feedback.The main winding of this transformer T1 and capacitor C1 form resonance circuit.Element R2, R3 and DZ1 form the biasing circuit that is used for transistor T R1.Preferably, transistor T R1 is an igbt transistor.Electronic igniting circuit also comprises Zener diode DZ2 and DZ3, with protection TR1, prevents the high voltage spikes on the grid.Current control circuit is made up of element X1, C6, R4 and R5, and wherein R5 is the current measurement divert shunt resistor.
Use above-mentioned current control circuit, the energy charge of resonance circuit (T1 and C1) will always be fixed as preset value.This preset value is defined by the triggering level of current measurement divert shunt resistor R5 and X1.The preset value that is used for the energy charge of resonance circuit is chosen as on the output of firing circuit and produces the required value of spark (spark) with appropriate energy.Like this, only, just can change the power output of firing circuit easily by changing the value of R5.
In output, produce the appropriate required energy of spark because only fill, so very high according to the efficient of electronic igniting circuit of the present invention to resonance circuit.By using this technology can reach about 90% efficient.And, very short because the current control circuit that combines with igbt transistor has guaranteed to be used for the deadline of igbt transistor, so this current control circuit makes that also producing this high efficiency circuit becomes possibility.
This electronic igniting circuit also comprises reset diode D2, inserts as the flyback diode that is used for protective transistor usually.Yet in electronic igniting circuit according to the present invention, reset diode D2 is as reset diode work.
For the electronic ignition unit, need circuit and transformer whole loads promptly output to (open circuit output) situation that do not have load fully from short circuit under, to work.When using fixed energies with the burst charging resonance circuit of phase 50-60KHz weekly, and the load on the output needs reset (discharge) of resonance circuit when not consuming that energy.If lack reset diode D2, and not discharge (resetting) in each cycle of resonance circuit, will reach the triggering level of current control circuit never so, and the charging of resonance circuit is out of hand.If the charging of resonance circuit is out of hand, then according to the loading condition of reality, in the circuit all may take place in principle.
Under different loading conditions, offer among the charging current of resonance circuit such as Fig. 2-5 institute and describe.
When the output short-circuit of resonance circuit, see Fig. 2, reset diode will discharge energy with its same amount that is charged from resonance circuit.Fig. 2 shows two curve-curves " 1 " and curve " C ".Curve " C " is that amplify in the cross section of curve " 1 ", and it is with the hunting of frequency of 50KHz.Therefore, curve " 1 " is the charging current burst of the 50KHz in the positive half-wave (10ms) of supply voltage.With reference now to curve " C ",, the charging of resonance circuit takes place during positive half period, and discharge during negative half-cycle.Because the output short circuit, so the necessary balance of the charging of resonance circuit and discharge promptly, removes the energy that offers resonance circuit once more at interdischarge interval.In Fig. 2, the area of positive half period equals the area of negative half-cycle, i.e. discharge equals charging.
See Fig. 3, when normal load imposed on output, reset diode will be only from resonance circuit discharge energy seldom.Energy remaining is by load consumption.This can see clearly that in Fig. 3 wherein greater than the area of negative half-cycle, that is, the charging of resonance circuit is higher than the discharge by reset diode D2 to the area of positive half period significantly.
Under special situation, it is inoperative that reset diode will become.When this situation occurs in all energy from resonance circuit and is all consumed by the bypass load.Described this example among Fig. 4, it has also shown the current spike pulse at the first bruss of each positive half period.These current spike pulses relate to the charging of the capacitor in the resonance circuit.
Fig. 5 shows does not have load to be connected to the situation of lead-out terminal.Because load does not have energy to consume, so the discharge of resonance circuit only can take place by reset diode D2.
It is very low that its characteristics of the combination of current control circuit and reset diode are to make high efficiency, cost, and the igniter of observing whole loading demands becomes possibility.Yet, be noted that in load to have under the situation of clear and definite and the characteristic known, can ignore reset diode, this is owing to knowing under the situation of load, charging that can be by the load balance resonance circuit is with the discharge of coupling resonance circuit.And, can use with all high frequency ferrite core high voltage transformer according to electronic igniting circuit of the present invention.
This electronic igniting circuit can also comprise aforesaid high frequency ferrite core high voltage transformer T1.These parts are not only the part of resonance circuit and oscillator, and will be voltage transformation low relatively on the main winding high pressure (20KV) on the output.
The output of this electronic igniting circuit is connected to spark point (spark electrode).
